Low Voltage UHS Analog Switch 2-Channel
Multiplexer/Demultiplexer
General Description
The NC7SB3157 is a high performance, Analog Switch 2-
channel CMOS multiplexer/demultiplexer from Fairchild’s
Ultra High Speed Series of TinyLogic
. The device is fabri-
cated 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 independent of the V
CC
operating range.
