1-of-16 decoder/demultiplexer with input latches
HEF4514B
MSI
DESCRIPTION
The HEF4514B is a 1-of-16 decoder/demultiplexer, having
four binary weighted address inputs (A
0
to A
3
), a latch
enable input (EL), and an active LOW enable input (E).
The 16 outputs (O
0
to O
15
) are mutually exclusive active
HIGH. When EL is HIGH, the selected output is
determined by the data on A
n
. When EL goes LOW, the
last data present at A
n
are 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 HEF4514B is
used as a demultiplexer, E is the data input and A
0
to
A
3
are the address inputs.
