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/Demulti-
plexer. The device is fabricated with advanced sub-micron
CMOS technology to achieve high speed enable and dis-
able times and low On Resistance. The break before make
select circuitry prevents disruption of signals on the B

Ports due to the switches temporarily being enabled
during select pin switching. The device is specified to oper-
ate 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.
