74HC238; 74HCT238

3-to-8 line decoder/demultiplexer

Rev. 4 — 27 January 2016

Product data sheet

1. 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 V

2. Features and benefits
