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

Unlike conventional CMOS devices, UltraCMOS?
devices are immune to latch-up.
Optional External Vss Control ( Vss EXT )
For proper operation, the Vss EXT control must be
grounded or at the Vss voltage specified in the

Operating Ranges table. When the Vss EXT control pin
on the package is grounded the switch FET’s are
biased with an internal low spur negative voltage
generator. For applications that require the lowest
possible spur performance, Vss EXT can be applied to

eliminate the spurs.

Switching Frequency
The PE43703 has a maximum 25 kHz switching rate
when Vss EXT is grounded. Switching rate is defined to
be the speed at which the DSA can be toggled across
attenuation states.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the PE43703 in
the 5x5 QFN package is MSL1.
Exposed Solder Pad Connection
The exposed solder pad on the bottom of the package
must be grounded for proper device operation.
Note: Ground C0.25, C0.5, C1 C2, C4, C8, C16 if not in use.
