DESCRIPTION
Each of these data selectors/multiplexers contain inverters and drivers to supply full binary decoding data selection to the AND-OR gates. Separate output-control inputs are provided for each of
the two 4-line sections.
The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (at the high-impedance state), the low impedance of the
single enabled output drives the bus line to a high or low logic level. Each output has its own output-enable (OE\) input. The outputs are disabled when their respective OE\ is high.
The SN54HC253 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC253 is characterized for operation from -40°C to 85 °C
