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 Y
0
or Y
1
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.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
