Control Logic Input
The PE4259 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 4) supporting
a +3-volt CMOS logic input, and requires a
dedicated +3-volt power supply connection on pin
6 (V
number of control lines required and simplifies the
switch control interface typically derived from a
CMOS Processor I/O port.
Complementary-pin control mode allows the
switch to operate using complementary control
pins CTRL and CTRL (pins 4 & 6), that can be
directly driven by +3-volt CMOS logic or a suitable
be used as a potential alternate source for SPDT
RF switch products used in positive control
voltage mode and operating within the PE4259
operating limits.
