4 ，输入数字多路复用器 4-Input Digital Multiplexer
General Description
Each of these Schottky-clamped data selectors/multiplexers 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.
