TinyLogic Low Voltage UHS SPDT Analog Switch
or 2:1 Multiplexer/Demultiplexer Bus Switch
General Description
The NC7SB3157 or FSA3157 is a high performance, sin-
gle-pole/double-throw (SPDT) Analog Switch or 2:1 Multi-
plexer/Demultiplexer Bus Switch from Fairchild’s Ultra High
Speed Series of TinyLogic. The device is fabricated with
advanced sub-micron CMOS technology 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 Port due to both 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 inde-
pendent of the V_CC operating range.
