1-of-16 decoder/demultiplexer with input latches
HEF4515B
MSI
DESCRIPTION
The HEF4515B 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
LOW. When EL is HIGH, the selected output is determined
by the data on An. When EL goes LOW, the 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 LOW. At
E HIGH, all outputs are HIGH. The enable input (E) does
not affect the state of the latch. When the HEF4515B is
used as a demultiplexer, E is the data input and A0 to
A3 are the address inputs.
