74HC238PW-Q100J 技术参数

74HC238-Q100; 74HCT238-Q100

3-to-8 line decoder/demultiplexer

Rev. 1 — 19 February 2013

Product data sheet

1. General description

The 74HC_HCT238_Q100 decodes three binary weighted address inputs (A0, A1 and

A2) to eight mutually exclusive outputs (Y0 to Y7). The device features three enable

inputs (E1, E2 and E3). Every output is LOW unless E1 and E2 are LOW and E3 is HIGH.

This multiple enable function allows easy parallel expansion to a 1-of-32 (5 to 32 lines)

decoder with just four 74HC_HCT238_Q100 ICs and one inverter. The

74HC_HCT238_Q100 can be used as an eight output demultiplexer by using one of the

active LOW enable inputs as the data input and the remaining enable inputs as strobes.

Inputs include clamp diodes that enable the use of current limiting resistors to interface

inputs to voltages in excess of V_CC

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

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