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.
2. Pins 16 and 17 are the CMOS controls that set the three operating
states.
3. Connect pin 18 to GND to enable the on-chip negative voltage generator.
Connect pin 18 to V
SS
(-3 V) to bypass and disable internal -3 V supply
generator. Also, see paragraph “Switching Frequency.”

Electrostatic Discharge (ESD) Precautions
When handling this UTSi 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 PE4280 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18=GND). The rate at which the
PE4280 can be switched is only limited to the
switching time if an external -3 V supply is
provided at pin 18 (V
SS
).
