NC7SZ3157
TinyLogic™ Low Voltage UHS Analog Switch 2-Channel
Multiplexer/Demultiplexer (Preliminary)
General Description
The NC7SZ3157 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.

Note 1:
Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 2:
The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3:
Control input must be held HIGH or LOW, it must not float.
