Nominal 3 V supply connection. A
bypass capacitor (100 pF) to the ground
plane should be placed as close as
possible to the pin
CMOS logic level:
High = RFCommon to RF1 signal path
Low = RFCommon to RF2 signal path
Ground connection. Traces should be
physically short and connected to ground
plane for best performance.

Electrostatic Discharge (ESD) Precautions
When handling this UTSi 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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UTSi CMOS
devices are immune to latch-up.
