-Binary to 1-of-16 Decoder
-1-to-16 Line Demultiplexer Fanout (Over Temperature Range) 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 (A0A3) as addresses. This E input also serves as a chip select …
