The PE4251 is a versatile RF CMOS switch that
supports two operating control modes; single-pin
control mode and complementary-pin control
mode.
Single-pin control mode enables the switch to

operate with a single control pin (pin 2) supporting
a +3.3 or 5.0-volt CMOS logic input, and requires

a dedicated +3.3 or 5.0-volt power supply
connection (pin 1). This mode of operation
reduces the number of control lines required and
simplifies the switch control interface typically
derived from a CMOS μ Processor I/O port.
Complementary-pin control mode allows the
switch to operate using complementary control
pins V1 and V2 (pins 2 & 1), that can be directly
driven by +3.3 or 5.0-volt CMOS logic or a suitable
μ Processor I/O port. This enables the PE4251 to
operate in positive control voltage mode within the
PE4251 operating limits.
