Data sheet acquired from Harris Semiconductor
SCHS280C
November 1997 - Revised July 2003
High-Speed CMOS Logic 4- to 16-Line
Decoder/Demultiplexer with Input Latches
Description
The CD54HC4514, CD74HC4514, and CD74HC4515 are
high-speed silicon gate devices consisting of a 4-bit strobed
latch and a 4- to 16-line decoder. The selected output is
enabled by a low on the enable input (E). A high on E inhibits
selection of any output. Demultiplexing is accomplished by
using the E input as the data input and the select inputs (A0-
A3) as addresses. This E input also serves as a chip select
when these devices are cascaded.
When Latch Enable (LE) is high the output follows changes
in the inputs (see truth table). When LE is low the output is
isolated from changes in the input and remains at the level
(high for the 4514, low for the 4515) it had before the latches
were enabled. These devices, enhanced versions of the
equivalent CMOS types, can drive 10 LSTTL loads.
