74HC237-Q100 - 3-to-8 line decoder/demultiplexer

General Description

The 74HC237-Q100 is a 3-to-8 line decoder, demultiplexer with latches at the three address inputs (An).

The 74HC237-Q100 essentially combines the 3-to-8 decoder function with a 3-bit storage latch.

When the latch is enabled (LE = LOW), the 74HC237-Q100 acts as a 3-to-8 active LOW decoder.

Key Features

  • Automotive product qualification in accordance with AEC-Q100 (Grade 1).
  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C.
  • Combines 3-to-8 decoder with 3-bit latch.
  • Multiple input enable for easy expansion or independent controls.
  • Active HIGH mutually exclusive outputs.
  • Wide supply voltage range from 2.0 V to 6.0 V.
  • CMOS low power dissipation.
  • High noise immunity.
  • Latch-up performance exceeds 100 mA per JE.

74HC237-Q100 3-to-8 line decoder, demultiplexer with address latches Rev. 3 — 11 January 2024 Product data sheet 1. General description The 74HC237-Q100 is a 3-to-8 line decoder, demultiplexer with latches at the three address inputs (An). The 74HC237-Q100 essentially combines the 3-to-8 decoder function with a 3-bit storage latch. When the latch is enabled (LE = LOW), the 74HC237-Q100 acts as a 3-to-8 active LOW decoder. When the latch enable (LE) goes from LOW-to-HIGH, the last data present at the inputs before this transition, is stored in the latches. Further address changes are ignored as long as LE remains HIGH. The output enable input (E1 and E2) controls the state of the outputs independent of the address inputs or latch operation.
