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.
Features
• High Speed Operation: tpd (Data to Y) = 16 ns typ (CL = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
