3 Description
The SN54SC8T151-SEP data selector/multiplexer
provides full binary decoding to select one of eight
data sources. The strobe (G) input must be at a low
logic level to enable the inputs. A high level at the
strobe terminal forces the standard output (Y) low and
the inverted output (W) high.
