9312/DM9312 One of Eight Line
Data Selectors/Multiplexers
General Description
These data selectors/multiplexers contain inverter/drivers
to supply full complementary, on-chip, binary decoded data
selection.
The 9312 is a single 8-bit multiplexer with complementary
outputs and a strobe control. When the strobe is low, the
function is enabled. When a high logic level is applied to the
strobe, the output is forced to the logic zero state regardless
of the logic level of the data inputs.
