RF Common
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.

Switching Frequency
The PE4274 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 18 = GND). The rate at which the
PE4274 can be switched is only limited to the
switching time if an external -3 V supply is
provided at (pin 18 = VSS).

Notes:
RF Ground Pad
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 V DC
requirement is met.
2. Pins 16 and 17 are the CMOS controls that set the four operating
states.
3. Connect pin 18 to GND to enable the negative voltage generator.
Connect pin 18 to VSS (-3V) to bypass and disable internal -3V supply
generator. See “Switching Frequency”.
