High-Speed, Low-Voltage, CMOS Analog Multiplexers/Switches
________________General Description
The MAX4617/MAX4618/MAX4619 are high-speed, lowvoltage, CMOS analog ICs configured as an 8-channel multiplexer (MAX4617), two 4-channel multiplexers (MAX4618), and three single-pole/double-throw (SPDT) switches (MAX4619). These CMOS devices can operate continuously with a +2V to +5.5V single supply. Each switch can handle Rail-to-Rail(R) analog signals. The off-leakage current is only 1nA at TA = +25C and 10nA at TA = +85C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.

Note 1: Voltages exceeding VCC or GND on any analog signal terminal are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

__________Applications Information
Power-Supply Considerations
Overview The MAX4617/MAX4618/MAX4619 construction is typical of most CMOS analog switches. They have two supply pins: VCC and GND. VCC and GND are used to drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analogsignal pin and both VCC and GND. If any analog signal exceeds VCC or GND, one of these diodes conducts. During normal operation, these and other reversebiased ESD diodes leak, forming the only current drawn from VCC or GND.
Virtually all the analog leakage current comes from the ESD diodes. 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 VCC 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 VCC and GND pins constitutes the analog-signal-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 either the same or opposite polarity. VCC and GND power the internal logic and set the input logic limits. Logic inputs have ESD-protection diodes to ground.

High-Speed, Low-Voltage, CMOS Analog Multiplexers/Switches
The logic-level thresholds are TTL/CMOS compatible when VCC is +5V. As VCC rises, the threshold increases; as VCC falls, the threshold decreases. For example, when VCC = +3V the guaranteed minimum logic-high threshold decreases to 2.0V
Pin Nomenclature
The MAX4617/MAX4618/MAX4619 are pin compatible with the industry-standard 74HC4051/74HC4052/ 74HC4053 and the MAX4581/MAX4582/MAX4583. In single-supply applications, they function identically and have identical logic diagrams, although these parts differ electrically. The pin designations and logic diagrams in this data sheet conform to the original 1972 specifications published by RCA for the CD4051/CD4052/CD4053. These designations differ from the standard Maxim switch and mux designations found on other Maxim data sheets (including the MAX4051/MAX4052/MAX4053) and may cause confusion. Designers who feel more comfortable with Maxim's standard designations are advised that the pin designations and logic diagrams on the MAX4051/MAX4052/MAX4053 data sheet may be freely applied to the MAX4617/MAX4618/MAX4619.
MAX4617/MAX4618/MAX4619
Power Supply These devices operate from a single supply between +2.5V and +5.5V. All of the bipolar precautions must be observed. At room temperature, they actually "work" with a single supply near or below +2V, although as supply voltage decreases, switch on-resistance becomes very high.
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence VCC on first, followed by the logic inputs and analog signals. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog-signal range to one diode drop below V CC and one diode drop above GND, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between VCC and GND should not exceed 6V. These protection diodes are not recommended if signal levels must extend to ground.

High-Frequency Performance
In 50 systems, signal response is reasonably flat up to 50MHz (see Typical Operating Characteristics). Above 20MHz, the on-response has several minor peaks that are highly layout dependent. The problem is not turning the switch on, but turning it off. The off-state switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off-isolation is about -50dB in 50 systems, becoming worse (approximately 20dB per decade) as frequency increases. Higher circuit impedances also degrade off-isolation. Adjacent channel attenuation is about 3dB above that of a bare IC socket and is entirely due to capacitive coupling.

NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORT AT SOCKET TERMINALS. OFF ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH. ON LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH. CROSSTALK (MAX4618/MAX4619) IS MEASURED FROM ONE CHANNEL (A, B, C) TO ALL OTHER CHANNELS. SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
