description

This data selector/multiplexer contains inverters and drivers tosupply full binary decoding data selection to the AND-OR-invertgates. Separate output-enable () inputs are provided for each of the two 4-linesections.

The 3-state outputs can interface with and drive data lines ofbus-organized systems. With all but one of the common outputsdisabled (at the high-impedance state), the low impedance of thesingle enabled output drives the bus line to a high or low logiclevel. Each section has its own output enable. The output is disabledwhen is high.

The SN74ALS353B is characterized for operation from 0°C to70°C.

Select inputs A and B are common to both sections.
