74HC238; 74HCT238  
3-to-8 line decoder/demultiplexer  
Rev. 7 — 2 September 2021  
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 VCC  
.
2. Features and benefits  
Wide supply voltage range from 2.0 to 6.0 V  
CMOS low power dissipation  
High noise immunity  
Demultiplexing capability  
Multiple input enable for easy expansion  
Ideal for memory chip select decoding  
Active HIGH mutually exclusive outputs  
Input levels:  
For 74HC238: CMOS level  
For 74HCT238: TTL level  
Complies with JEDEC standards  
JESD8C (2.7 V to 3.6 V)  
JESD7A (2.0 V to 6.0 V)  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
