TinyLogic
UHS 1-of-2 Decoder/Demultiplexer
General Description
The NC7SZ19 is a 1-of-2 decoder with a common output
enable. 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 V
CC
operating range. The device is specified to
operate over the 1.65V to 5.5V V
CC
operating range. The
inputs and outputs are high impedance when V
CC
is 0V.
Inputs tolerate voltages up to 5.5V independent of V
CC
operating range.
