74LV138  
3-to-8 line decoder/demultiplexer; inverting  
Rev. 03 — 15 November 2007  
Product data sheet  
1. General description  
The 74LV138 is a low-voltage Si-gate CMOS device that is pin and function compatible  
with 74HC138 and 74HCT138.  
The 74LV138 is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted  
address inputs (A0, A1 and A2) and, when enabled, provides eight mutually exclusive  
active LOW outputs (Y0 to Y7).  
There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3).  
Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.  
This multiple enable function allows easy parallel expansion of the device to a 1-of-32  
(5 lines to 32 lines) decoder with just four 74LV138 devices and one inverter. The  
74LV138 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. Unused  
enable inputs must be permanently tied to their appropriate active HIGH or LOW state.  
2. Features  
Wide operating voltage: 1.0 V to 5.5 V  
Optimized for low voltage applications: 1.0 V to 3.6 V  
Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V  
Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 °C  
Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and  
Tamb = 25 °C  
Demultiplexing capability  
Multiple input enable for easy expansion  
Ideal for memory chip select decoding  
Active LOW mutually exclusive outputs  
ESD protection:  
HBM JESD22-A114E 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
