DM74S253 Dual 3-STATE 1-of-4 Line Data Selector/Multiplexer
General 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 3-STATE outputs can interface directly with 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 enable output will drive the bus line to a HIGH or LOW logic level.
