HD74HC153

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) Function Table Inputs Select B X L L L L H H H H X : A X L L H H L L H H Irrelevant Data C0 X L H X X X X X X C1 X X X L H X X X X C2 X X X X X L H X X C3 X X X X X X X L H Strobe G H L L L L L L L L Outputs Y L L H L H L H L H HD74HC153 Pin Arrangement Strobe Select 1G 1 B 2 1C3 3 1C2 4 1G 1C3 2G 2C3 16 VCC 15 2G Strobe 14 Select A 13 2C3 12 2C2 11 2C1 10 2C0 9 2Y Output Data Inputs 1C2 1C1 B Data Inputs 1C1 5 1C0 6 2C2 B B 2C1 A A 2C0 2Y 1C0 B A 1Y A Output 1Y 7 GND 8 (Top view) 2 HD74HC153 DC Characteristics Ta = 25°C Item Input voltage Symbol VIH Ta = –40 to +85°C Max — — — 0.5 1.35 1.8 — — — — — 0.1 0.1 0.1 0.33 0.33 ±1.0 40 µA µA I OL = 4 mA I OL = 5.2 mA Vin = VCC or GND Vin = VCC or GND, Iout = 0 µA V I OH = –4 mA I OH = –5.2 mA Vin = VIH or VIL I OL = 20 µA V Vin = VIH or VIL I OH = –20 µA V Unit V T...
