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.
Optional External Vss Control (
For proper operation, the Vss
grounded or at the Vss voltage specified in the
Operating Ranges table. When the Vss
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
bypass the internal negative voltage generator to
eliminate the spurs.
Switching Frequency
The PE43703 has a maximum 25 kHz switching rate
when Vss
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.
