FEATURES
GENERAL DESCRIPTION
The 74HC/HCT4514 are high-speed Si-gate CMOS
devices and are pin compatible with “4514” of the “4000B”
series. They are specified in compliance with JEDEC
standard no. 7A.

The 74HC/HCT4514 are 4-to-16 line
decoders/demultiplexers having four binary weighted
address inputs (A
(LE), and an active LOW enable input (E). The 16 outputs
(Q
is HIGH, the selected output is determined by the data on
A
stored in the latches and the outputs remain stable. When
E is LOW, the selected output, determined by the contents
of the latch, is HIGH. At E HIGH, all outputs are LOW. The
enable input (E) does not affect the state of the latch.
When the “4514” is used as a demultiplexer, E is the data
input and A
