MAX4561EUT+-MAX4561EUT+T-MAX4568EUK+T
±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 70Ωat 5V (120Ωat 3V) on-resistance is
matched between channels to 2Ωmax, 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.

Applications Information

Do not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always sequence V+ on first, fol-
lowed by the logic inputs, NO/NC, or COM.
Operating Considerations for
High-Voltage Supply

The MAX4561/MAX4568/MAX4569 are capable of
+12V single-supply operation with some precautions.
The absolute maximum rating for V+ is +13V (refer-
enced to GND). When operating near this region,
bypass V+ with a 0.1µF min capacitor to ground as
close to the device as possible.
