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.
Exposed Solder Pad Connection
The exposed solder pad on the bottom of the package
must be grounded for proper device operation. 
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS"
devices are immune to latch-up.
Switching Frequency
The PE43503 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.
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.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the PE43503 in
the 24-lead 4x4 QFN package is MSL1.
