DM74S253
Dual 3-STATE 1-of-4 Line Data Selector/Multiplexer
General Description
Each of these Schottky-clamped data selectors/multiplex-
ers contains inverters and drivers to supply fully comple-
mentary, on-chip, binary decoding data selection to the
AND-OR gates. Separate output control inputs are pro-
vided 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.
Features
s 3-STATE version of S153 with same pin-out
s Schottky-diode-clamped transistors
s Permits multiplexing from N lines to 1 line
s Performs parallel-T-serial conversion
s Strobe/output control
s High fan-out totem-pole outputs
s Typical propagation delay
From data to output 6 ns
From select to output 12 ns
s Typical power dissipation 275 mW
