description

Each of these data selectors/multiplexers contains inverters anddrivers to supply full binary decoding data selection to the AND-ORgates. Separate output control inputs are provided for each of thetwo four-line sections.

The three-state outputs can interface with and drive data lines ofbus-organized systems. With all but one of the common outputsdisabled (at a high-impedance state), the low-impedance of the singleenabled output will drive the bus line to a high or low logic level.Each output has its own strobe (G\). The output is disabled when itsstrobe is high.

The 54AC11253 is characterized for operation over the fullmilitary temperature range of - 55°C to 125°C. The74AC11253 is characterized for operation from - 40°C to85°C.

Address inputs A and B are common to both sections.
