±15kV ESD-Protected, Low-Voltage, SPDT/SPST, CMOS Analog Switches
General Description
T h e MAX4561/MAX4568/MAX4569 are low-voltage, E S D - p r o t e c t e d analog switches. The normally open (NO) and normally closed (NC) inputs are protected against ±15kV electrostatic discharge (ESD) without latchup or damage, and the COM input is protected against 2.5kV ESD. These switches operate from a single +1.8V to +12V supply. The 70 at 5V (120 at 3V) on-resistance is matched between channels to 2 max, and is flat (4 max) over the specified signal range. The switches can handle Rail-to-Rail® analog signals. Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The digital input has +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply. The MAX4561 is a single-pole/double-throw (SPDT) switch. The MAX4568 NO and MAX4569 NC are single-pole/single-throw (SPST) switches. The MAX4561 is available in a 6-pin SOT23 package, a n d the MAX4568/MAX4569 are available in 5-pin SOT23 packages.

Note 1: Signals on NO, NC, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward 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.
