description

This data selector/multiplexer contains inverters and drivers to supply full binary decoding data selection to the AND-OR-invert gates. Separate output-enable () 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 section has its own output enable. The output is disabled when is high.

The SN74ALS353B is characterized for operation from 0°C to 70°C.

Select inputs A and B are common to both sections.
