±15kV ESD-Protected, Low-Voltage,
SPDT/SPST, CMOS Analog Switches
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.
