ULP 2-Input Non-Inverting Multiplexer
General Description
The NC7SP157 is a single 2-Input Non-Inverting Multiplexer from Fairchild’s Ultra Low Power (ULP) Series of
TinyLogic
. Ideal for applications where battery life is criti-
cal, this product is design ed for ultra low power cons umption within the V
The internal circ uit is composed o f a minimum of inverter
stages, including the output buffer, to enable ultra low static
and dynamic power.
The NC7SP157, for lower drive requirements, is uniquely
designed for optimi zed po wer and speed, and is fab ri cat ed
with an advanced CMOS technology to achieve best in
class speed operation while maintaining extremely low
CMOS power dissipation.
