HD74LS253
Dual 4-line-to-1-line Data Selectors / Multiplexers
(with three-state outputs)
REJ03D0468–0300
Rev.3.00
Jul.15.2005
This data selector / multiplexer contains inverters and drivers to supply fully complementary, on-ship, binary decoding
data selection to 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 high-
impedance state) the low-impedance of the single enabled output will drive the bus line to a high or low logic level.
