FSA3357 Low Voltage SP3T Analog Switch (3:1 Multiplexer/Demultiplexer)
FSA3357
Low Voltage SP3T Analog Switch
(3:1 Multiplexer/Demultiplexer)
General Description
The FSA3357 is a high performance, single-pole/triple-throw
(SP3T) Analog Switch or 3:1 Multiplexer/Demultiplexer. The
device is fabricated with advanced sub-micron CMOS technol-
ogy to achieve high speed enable and disable times and low On
Resistance. The break before make select circuitry prevents
disruption of signals on the B
0
, B
1
, or B
2
Ports due to the
switches temporarily being enabled during select pin switching.
The device is specified to operate over the 1.65 to 5.5V V
CC
operating range. The control input tolerates voltages up to 5.5V
independent of the V
CC
operating range.
