74HC138; 74HCT138  
3-to-8 line decoder/demultiplexer; inverting  
Rev. 8 — 7 April 2020  
Product data sheet  
1. General description  
The 74HC138; 74HCT138 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 will be HIGH 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 '138 ICs  
and one inverter. The '138 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 VCC  
.
2. Features and benefits  
Complies with JEDEC standard no. 7A  
Input levels:  
For 74HC138: CMOS level  
For 74HCT138: TTL level
