SN74LS253 Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs | TI.com

SN74LS253 (ACTIVE) Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

 

Description

Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections.

The three-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (at a high-impedance state) the low-impedance of the single enabled output will drive the bus line to a high or low logic level.
