NC7SZ157
TinyLogic UHS 2-Input Non-Inverting Multiplexer
General Description
Features
■ Space saving SC70-6 lead surface mount package
■ Ultra Small MicroPak leadless package
■ Ultra High Speed
The NC7SZ157 is a single, high performance, 2 to 1
CMOS non-inverting multiplexer from Fairchild’s Ultra High
Speed Series of TinyLogic . The device is fabricated with
advanced CMOS technology to achieve ultra high speed
with high output drive while maintaining low static power
dissipation over a broad VCC operating range. The device
■ Broad VCC operating range: 1.65V to 5.5V
■ Power down high impedance input/output
is specified to operate over the 1.65V to 5.5V VCC operat-
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Patented noise/EMI reduction circuitry implemented
ing range. The inputs and outputs are high impedance
when VCC is 0V. Inputs tolerate voltages up to 5.5V inde-
pendent of VCC operating range.
