MAXIM MAX4564 Technical data

General Description

The MAX4564 is a low-voltage, dual-supply, singlepole/double-throw (SPDT) analog switch designed to operate from dual ±1.8V to ±6V or single +1.8V to +12V supplies. The low on-resistance (R

ON

= 40Ω at ±5V) and low power consumption (5µW) make this part ideal for audio, video, and battery-powered applications. This switch offers low leakage currents (1nA max) and fast switching speeds (tON= 60ns and t

OFF

= 40ns at ±5V, max).

The MAX4564 is available in 8-pin SOT23 and µMAX packages.

Note 1: Signals on NO, NC, COM, IN, or EN exceeding V+ or V- 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.
