Name
Description
1
V_DD
Nominal 3 V supply connection. A by-
pass capacitor (100 pF) to the ground
plane should be placed as close as pos-
sible to the pin
2
CTRL
CMOS or TTL logic level:
High = RFC to RF1 signal path
Low = RFC to RF2 signal path
3
GND
Ground connection. Traces should be
physically short and connected to ground
plane for best performance.

RFC
Common RF port for switch (Note 1)
5

RF2 port (Note 1)
6
GND
Ground connection. Traces should be
physically short and connected to ground
plane for best performance.
7
GND
Ground connection. Traces should be
physically short and connected to ground
plane for best performance.
8
RF1
RF1 port (Note 1)
Note 1: All RF pins must be DC blocked with an external
series capacitor or held at 0 V_DC.

Absolute Maximum Ratings are those values
listed in the above table. Exceeding these values
may cause permanent device damage.
Functional operation should be restricted to the
limits in the DC Electrical Specifications table.
Exposure to absolute maximum ratings for
extended periods may affect device reliability.
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 in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.

Control Logic
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.)
