The control logic input pin (CTRL) is typically
driven by a 3-volt CMOS logic level signal, and
has a threshold of 50% of V
DD
. For flexibility to
support systems that have 5-volt control logic
drivers, the control logic input has been designed
to handle a 5-volt logic HIGH signal. (A minimal
current will be sourced out of the V
DD
pin when the
control logic input voltage level exceeds V
DD
.)

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 rating specified in Table 3.
Note 1: All RF pins must be DC blocked with an external
series capacitor or held at 0 V
DC
.
