74HC238; 74HCT238

3-to-8 line decoder/demultiplexer

Rev. 5 — 13 June 2018

Product data sheet

General description

The 74HC238; 74HCT238 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 and E2 and E3). Every output will be 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 '238 ICs and one inverter. The '238 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. This

enables the use of current limiting resistors to interface inputs to voltages in excess of
