HD74HC153
Dual 4-to-1-line Data Selectors/Multiplexers
Description
Information on the data inputs of each multiplexer is selected by the address on the A and B inputs, and is
presented on the Y outputs. Each multiplexer possesses a strobe input which enables it when taken to a low
logic level. When a high logic level is applied to a strobe input, the output of its associated multiplexer is
taken low.
Features
⢠High Speed Operation: tpd (D to Y) = 13 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)
