Power Supply Pin
Notes: 1. Pins 3 through 7 may be tied to ground if desired, but
they are not connected to ground internal to the package
2. All RF pins must be DC blocked with an external series
capacitor or held at 0 VDC.
Exposed Solder Pad Connection
The exposed solder pad on the bottom of the package
must be grounded for proper device operation.

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.
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.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the PE43204 in
the 12-lead 3x3 QFN package is MSL1.
Switching Frequency
The PE43204 has a maximum 25 kHz switching rate.
Switching rate is defined to be the speed at which the
DSA can be toggled across attenuation states.
