54LS153/DM54LS153/DM74LS153 Dual 4-Line to 1-Line Data Selectors/Multiplexers
June 1989
54LS153/DM54LS153/DM74LS153
Dual 4-Line to 1-Line Data Selectors/Multiplexers
General Description
Each of these data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR-invert gates.
Separate strobe inputs are provided for each of the two
four-line sections.
