74HCT237 - High-Speed CMOS Logic 3 to 8-Line Decoder/Demultiplexer

This page provides the datasheet information for the 74HCT237, a member of the 74HC237 High-Speed CMOS Logic 3 to 8-Line Decoder/Demultiplexer family.

Description

Both circuits have three binary select inputs (A0, A1 and A2) that can be latched by an active High Latch Enable (LE) signal to isolate the outputs from select-input changes.

A “Low” LE makes the output transparent to the input and the circuit functions as a one-of-eight decoder.

Features

  • Select One of Eight Data Outputs - Active Low for CD74HC137 and CD74HCT137 - Active High for ’HC237 and CD74HCT237.
  • l/O Port or Memory Selector.
  • Two Enable Inputs to Simplify Cascading.
  • Typical Propagation Delay of 13ns 15pF, TA = 25oC (CD74HC237) at VCC = 5V,.
  • Fanout (Over Temperature Range) - Standard Outputs.
  • 10 LSTTL Loads - Bus Driver Outputs.
  • . . . 15 LSTTL Loads.
  • Wide Operating T.
