Ultra Low ON-Resistance, +1.1V to +4.5V Single Supply, SPST Analog Switches
The Intersil ISL43L110 and ISL43L111 devices are low ON-resistance, low voltage, bidirectional, single pole/single throw (SPST) analog switches designed to operate from a single +1.1V to +4.5V supply. Targeted applications include battery powered equipment that benefit from low RON resistance, excellent RON flatness, and fast switching speeds (tON = 8ns, tOFF = 5ns). The digital logic input is 1.8V CMOS compatible when using a single +3V supply. Cell phones, for example, often face ASIC functionality limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance. This family of parts may be used to switch in additional functionality while reducing ASIC design risk. The ISL43L11X are offered in a 5 lead SC70 package, alleviating board space limitations. The ISL43L110 has one normally open (NO) switch and ISL43L111 has one normally closed (NC) switch.

Detailed Description
The ISL43L110 and ISL43L111 are bidirectional, single pole/single throw (SPST) analog switches. They offer precise switching capability from a single +1.1V to 4.5V supply with ultra low on-resistance and high speed operation. With a single supply of 4.3V the typical onresistance is only 0.21, with a typical turn-on and turn-off time of: tON = 8ns, tOFF = 5ns. The devices are especially well suited for portable battery powered equipment due to its low operating supply voltage (1.1V), low power consumption (1.8W max), low leakage currents (200nA max), and the tiny SC70 packaging. The ISL43L110 is a normally open (NO) SPST analog switch. The ISL43L111 is a normally closed (NC) SPST analog switch.
Supply Sequencing and Overvoltage Protection
With any CMOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the IC. All I/O pins contain ESD protection diodes from the pin to V+ and to GND (see Figure 6). To prevent forward biasing these diodes, V+ must be applied before any input signals, and the input signal voltages must remain between V+ and GND. If these conditions cannot be guaranteed, then precautions must be implemented to prohibit the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. The following two methods can be used to provided additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the V+ rail. Logic inputs can be protected by adding a 1k resistor in series with the input (see Figure 6). The resistor limits the input current below the threshold that produces permanent

ISL43L110, ISL43L111
damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not acceptable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low RON switch. Connecting schottky diodes to the signal pins as shown in Figure 6 will shunt the fault current to the supply or to ground thereby protecting the switch. These schottky diodes must be sized to handle the expected fault current.
Logic-Level Thresholds
This switch family is 1.8V CMOS compatible (0.5V and 1.4V) over a supply range of 2V to 3.6V (See Figure 15). At 3.6V the VIH level is about 1.1V. This is still below the 1.8V CMOS guaranteed high output minimum level of 1.4V, but noise margin is reduced. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to V+ with a fast transition time minimizes power dissipation.

High-Frequency Performance
In 50 systems, signal response is reasonably flat even past 100MHz (See Figure 16). The frequency response is very consistent over a wide V+ range, and for varying analog signal levels.

FIGURE 6. OVERVOLTAGE PROTECTION
An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch's input to its output. Off Isolation is the resistance to this feedthrough. Figure 17 details the high Off Isolation rejection provided by this family. At 100kHz, Off Isolation is about 65dB in 50 systems, decreasing approximately 20dB per decade as frequency increases. Higher load impedances decrease Off Isolation due to the voltage divider action of the switch OFF impedance and the load impedance.
Power-Supply Considerations
The ISL43L11X construction is typical of most single supply CMOS analog switches in that they have two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL43L11X 4.7V maximum supply voltage provides plenty of room for the 10% tolerance of 4.2V supplies, as well as room for overshoot and noise spikes. The minimum recommended supply voltage is 1.1V. It is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. Refer to the electrical specification tables and Typical Performance curves for details. V+ and GND also power the internal logic and level shiftier. The level shiftier converts the input logic levels to switched V+ and GND signals to drive the analog switch gate terminals. This family of switches cannot be operated with bipolar supplies, because the input switching point becomes negative in this configuration.
Leakage Considerations
Reverse ESD protection diodes are internally connected between each analog-signal pin and both V+ and GND. One of these diodes conducts if any analog signal exceeds V+ or GND. Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either V+ or GND and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the V+ and GND pins constitutes the analogsignal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog signal paths and V+ or GND.
