产品概述
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.
