The MAX4620/MAX4630/MAX4640 are quad 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 four
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 MAX4620/MAX4630/MAX4640 are capable of
+12V single-supply operation with some precautions.
The absolute maximum rating for V+ is 13V (referenced
to GND). When operating near this region, bypass V+
with a minimum 0.1µF capacitor to ground as close to
the IC as possible.
