TinyLogic UHS 1-of-2 Non-Inverting Demultiplexer
with 3-STATE Deselected Output
General Description
The NC7SZ18 is a 1-of-2 non-inverting demultiplexer. The
device will buffer the data on the A pin and pass to either
output Y₀ or Y₁ dependent on whether state of the select
pin (S) is LOW or HIGH respectively. The deselected out-
put will be placed into a high impedance state. 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.
Features
s Space saving SC70 6-lead surface mount package
