HD74HC352

HD74HC352 Dual 4-to-1-line Data Selectors/Multiplexers Description Each of these data selectors/multiplexers contains inverters and drivers to supply fully complementary binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs (G) are provided for each of the two four-line sections.
