This pin supports two interface options:
Single-pin control mode . A nominal 3-
volt supply connection is required.
Complementary-pin control mode . A
complementary CMOS control signal

Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS?
devices are immune to latch-up.
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 specified rating.
Note 3. All RF pins must be DC blocked with an external
series capacitor or held at 0 V DC .
