HD74HC154
4-to-16-line Decoder/Demultiplexer
Description
The HD74HC154 has 4 binary select inputs (A, B, C and D). IF the device is enabled these inputs
determine which one of the 16 normally high outputs will go low. Two active low enables (G₁ and G₂) are
provided to ease cascading of decoders with little or no external logic.
Features
• High Speed Operation: t_pd (A, B, C, D to Y) = 19 ns typ (C_L = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: V_CC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: I_CC (static) = 4 µA max (Ta = 25°C)
