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.
