3-to-8 line decoder, demultiplexer with address latches

Rev. 1 — 14 January 2013

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. All outputs are HIGH unless E1 is LOW and E2 is HIGH.

The 74HC237-Q100 is ideally suited for implementing non-overlapping decoders in

3-state systems and strobed (stored address) applications in bus-oriented systems.

This product has been qualified to the Automotive Electronics Council (AEC) standard

Q100 (Grade 1) and is suitable for use in automotive applications.
