9312/DM9312 One of Eight Line Data Selectors/Multiplexers General Description Features 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.
