UHS 1-of-2 Non-Inverting Demultiplexer
with 3-STATE Deselected Output
General Description
The NC7SZ18 is a 1-of- 2 non-invert ing demultipl exer. The
device will buffer the data on the A pin and pass to either
output Y
or Y1 dependent on whethe r state of the select
0
pin (S) is LOW or HIGH respecti vely. The deselected output will be placed into a high impedance state. The device
is fabricated with a dvanced CMOS technolo gy to achieve
ultra high speed with high outpu t drive while maintaining
low static power dissipati on over a broad V
range. The device is s pecified to operate over the 1.6 5V to
5.5V V
operating range. The inputs and outputs are high
CC
impedance when V
5.5V independent of V
is 0V. Inputs tolerate voltages up to
CC
operating range.
