General Description
Features
The MAX4561/MAX4568/MAX4569 are low-voltage,
ESD-protected analog switches. The normally open
(NO) and normally closed (NC) inputs are protected
against 15ꢀk electrostatic discharge (ESD) without
latchup or damage, and the COM input is protected
against 2.5ꢀk ESD.

These switches operate from a single +1.8k to +12k
supply. The 70 at 5k (120 at 3k) 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-leaꢀage current
is only 0.5nA at +25°C and 5nA at +85°C. The digital
input has +0.8k to +2.4k logic thresholds, ensuring
TTL/CMOS-logic compatibility when using a single +5k
supply. The MAX4561 is a single-pole/double-throw
(SPDT) switch. The MAX4568 NO and MAX4569 NC are
single-pole/single-throw (SPST) switches.
