MSI
1-of-16 decoder/demultiplexer with input latches
last data present at An 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 A0 to
A3 are the address inputs.
DESCRIPTION
The HEF4514B is a 1-of-16 decoder/demultiplexer, having
four binary weighted address inputs (A0 to A3), a latch
enable input (EL), and an active LOW enable input (E).
The 16 outputs (O0 to O15) are mutually exclusive active
HIGH. When EL is HIGH, the selected output is
determined by the data on An. When EL goes LOW, the
