June 1989
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
