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.

Exposed Solder Pad Connection
The exposed solder pad on the bottom of the package
must be grounded for proper device operation.
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
rate specified in Table 3.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Switching Frequency
The PE94302 has a maximum 25 kHz switching rate.
