The MAX4575/MAX4576/MAX4577 are dual SPST
CMOS analog switches with circuitry providing ±15kV
ESD protection on the NO and NC pins. The CMOS
switch construction provides rail-to-rail signal handling
while consuming virtually no power. Each of the two

CMOS Analog Switches
switches is independently controlled by a TTL/CMOS-
level-compatible digital input.
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.
The MAX4575/MAX4576/MAX4577 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 minimum 0.1µF capacitor to ground
as close to the IC as possible.
The MAX4575/MAX4576/MAX4577 are ±15kV ESD pro-
tected (according to IEC 1000-4-2) at the NC/NO termi-
nals. To accomplish this, bidirectional SCRs are
included on-chip between these terminals. When the
voltages at these terminals go Beyond-the-Rail™, the
corresponding SCRs turns on in a few nanoseconds
