CD74HC154 - 4- to 16-Line Decoder/Demultiplexer

General Description

A High on either enable input forces the output into the High state.

The demultiplexing function is performed by using the four input lines, A0 to A3, to select the output lines Y0 to Y15, and using one enable as the data input while holding the other enable low.

Key Features

  • Two Enable Inputs to Facilitate Demultiplexing and Cascading Functions.
  • Fanout (Over Temperature Range) - Standard Outputs.
  • 10 LSTTL Loads - Bus Driver Outputs.
  • . . . 15 LSTTL Loads.
  • Wide Operating Temperature Range . . . -55oC to 125oC.
  • Balanced Propagation Delay and Transition Times.
  • Significant Power Reduction Compared to LSTTL Logic ICs.
  • HC Types - 2V to 6V Operation - High Noise Immunity: NIL =.
