HD74HC154 - 4-to-16-line Decoder/Demultiplexer

General 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 (G 1 and G 2) are provided to ease cascading of decoders with little or no external logic.

Key Features

  • High Speed Operation: tpd (A, B, C, D to Y) = 19 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) HD74HC154 Function Table Inputs G1 L L L L L L L L L L L L L L L L L H H X : G2 L L L L L L L L L L L L L L L L H L H D L L L L L L L L H H H H H H H H X X X C L L L L H H H H L L L L H H H H X X X B L.
