MAXIM MAX4561, MAX4568, MAX4569 Technical data
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 70Ω at 5V (120Ω at 3V) on-resistance is
matched between channels to 2Ω max, and is flat (4Ω
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,
and the MAX4568/MAX4569 are available in 5-pin
SOT23 packages.

(Notes 2, 3)
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.
