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 rating specified.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.
Switching Frequency
The PE4256 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18=GND).

Notes:
1.
RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do not require
DC blocking capacitors for proper operation if the 0 VDC requirement
is met.
Pins 16 and 17 are the CMOS controls that set the three operating
states.
Connect pin 18 to GND to enable the on-chip negative voltage
generator. Connect pin 18 to V
SS
(-3V) to bypass and disable internal
-3V supply generator.
