Ground Connection. Traces should be
physically short and connected to the
ground plane. This pin is connected to
the exposed solder pad that also must
be soldered to the ground plane for best
performance.

Table 4. Absolute Maximum Ratings
Exceeding absolute maximum ratings may cause
permanent damage. Operation should be
restricted to the limits in the Operating Ranges
table. Operation between operating range
maximum and absolute maximum for extended
periods may reduce reliability.
Control Logic Input
The control logic input pin (CTRL) is typically
driven by a 3-volt CMOS logic level signal. For
flexibility to support systems that have 5-volt
control logic drivers, the control logic input has
been designed to handle a standard 5-volt TTL
control signal. This TTL control signal input must
not exceed 5-volts or damage to the switch could
result.

Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the rating specified in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
