NC7SB3157
TinyLogic 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 VCC
operating range. The control input tolerates voltages up to
5.5V independent of the VCC operating range.
Features
s Useful in both analog and digital applications
s Space saving SC70 6-lead surface mount package
s Low on resistance; < 10Ω on typ @ 3.3V VCC
s Broad VCC operating range; 1.65V to 5.5V
s Power down high impedance control input
s Overvoltage tolerance of control input to 7.0V
s Break before make enable circuitry
