Dual-Supply, Low-On-Resistance, SPST, CMOS Analog Switches
_______________General Description
The MAX4516/MAX4517 are single-pole/single-throw (SPST), CMOS, low-voltage, dual-supply analog switches with very low switch on-resistance. The MAX4516 is normally open (NO). The MAX4517 is normally closed (NC). These CMOS switches can operate continuously with dual supplies between 1V and 6V. Each switch can handle rail-to-rail analog signals. The off-leakage current maximum is only 1nA at +25C or 20nA at +85C. The digital input is referenced to the positive power supply and is CMOS compatible. For pin-compatible parts for use with a single supply, refer to the MAX4514/MAX415.

Voltages exceeding V+ or V- on any 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
The MAX4516/MAX4517 operate with power-supply voltages from 1V to 6V, but are tested and guaranteed only with 5V supplies. Similarly, they will operate with a single +2V to +12V supply, but logic-level inputs can shift with higher voltages. The pin-compatible MAX4514/MAX4515 are recommended for use with a single supply. The MAX4516/MAX4517 construction is typical of most CMOS analog switches, except that they have only two supply pins: V+ and V-. V+ and V- drive the internal CMOS switches and set their analog voltage limits. Reverse ESD-protection diodes are internally connected between each analog-signal pin and both V+ and V-. One of these diodes conducts if any analog signal exceeds V+ or V-. Virtually all the analog leakage current comes from the ESD diodes to V+ or V-. 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 V- 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 Vpins 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 the same or opposite polarity. There is no connection between the analog-signal paths and V+ or V-.
V+ and V- also power the internal logic and logic-level translators. The logic-level translators convert the logic levels to switched V+ and V- signals to drive the analog signal gates.
Logic-Level Thresholds
The logic-level thresholds are CMOS-compatible but not TTL-compatible. Since these parts have no ground pin, the logic-level threshold is referenced to V+. The threshold limits are V+ = -1.5V and V+ = -3.5V for V+ levels between +6V and +3V. When V+ = +2V, the logic threshold is approximately 0.6V. Do not connect the MAX4516/MAX4517's V+ to +3V and then connect the logic-level pins to logic-level signals that operate from a +5V supply. TTL levels can exceed +3V and violate the absolute maximum ratings, damaging the part and/or external circuits.
High-Frequency Performance
In 50 systems, signal response is reasonably flat up to 250MHz (see Typical Operating Characteristics). Above 20MHz, the on response has several minor peaks that are highly layout dependent. The problem is not in turning the switch on; it's in turning it off. The offstate switch acts like a capacitor and passes higher frequencies with less attenuation. At 10MHz, off isolation is about -48dB in 50 systems, decreasing (approximately 20dB per decade) as frequency increases. Higher circuit impedances also cause off isolation to decrease. Off isolation is about 3dB above that of a bare IC socket, and is due entirely to capacitive coupling.
