54LS352/DM74LS352 Dual 4-Line to
1-Line Data Selectors/Multiplexers
General Description
Each of these data selectors/multiplexers contains invert-
ers and drivers to supply fully complementary, on-chip, bi-
nary decoding data selection to the AND-OR-invert gates.
Separate strobe inputs are provided for each of the two
four-line sections.
