1 / 19 page SN54HC253, SN74HC253 DUAL 4LINE TO 1LINE DATA SELECTORS/MULTIPLEXERS WITH 3STATE OUTPUTS SCLS133E − DECEMBER 1982 − REVISED SEPTEMBER 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 3-State Version of ’HC153 D Wide Operating Voltage Range of 2 V to 6 V D High-Current Inverting Outputs Drive Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 9 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Permit Multiplexing From n Lines to One Line D Perform Parallel-to-Serial Conversion description/ordering information Each of these data selectors/multiplexers contains inverters and drivers to supply full binary decoding data selection to the AND-OR gates. Separate output-control 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 (in the high-impedance state), the low impedance of the single enabled output drives the bus line to a high or low logic level. Each output has its own output-enable (OE) input. The outputs are disabled when their respective OE is high.
