Power-Supply Sequencing and
Overvoltage Protection
Caution: Do not exceed the Absolute Maximum
Ratings since stresses beyond the listed ratings
may cause permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Improper supply sequencing can
force the switch into latchup, causing it to draw exces-
sive supply current. The only way out of latchup is to
recycle the power and reapply properly. Connect all
ground pins first, apply power to V
CC
, and finally apply
signals to X_, Y_, and common terminals. Follow the
reverse order upon power-down.
