General Description

The MAX4561/MAX4568/MAX4569 are low-voltage,

ESD-protected 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

Ω at 5V (120Ω at 3V) on-resistance is

matched between channels to 2

Ω max, and is flat (4Ω

max) over the specified signal range. The switches can

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,

and the MAX4568/MAX4569 are available in 5-pin

SOT23 packages.
