Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers  
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor  
product management systems do not have the ability to manage part nomenclature that utilizes an underscore  
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain  
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated  
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please  
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74LCX138  
Low Voltage 1-of-8 Decoder/Demultiplexer  
with 5V Tolerant Inputs  
General Description  
Features  
5V tolerant inputs  
The LCX138 is a high-speed 1-of-8 decoder/demultiplexer.  
This device is ideally suited for high-speed memory chip  
select address decoding. The multiple input enables allow  
parallel expansion to a 1-of-24 decoder using just three  
LCX138 devices or a 1-of-32 decoder using four LCX138  
devices and one inverter.  
2.3V to 3.6V VCC specifications provided  
6.0 ns tPD max (VCC = 3.3V), 10 µA ICC max  
Power down high impedance inputs and outputs  
±24 mA output drive (VCC = 3.0V)  
The 74LCX138 is fabricated with advanced CMOS technol-  
ogy to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
ESD performance:  
Human body model > 2000V  
Machine model > 200V

Functional Description  
The LCX138 high-speed 1-of-8 decoder/demultiplexer  
accepts three binary weighted inputs (A0, A1, A2) and,  
when enabled, provides eight mutually exclusive active-  
LOW outputs (O0–O7). The LCX138 features three Enable  
inputs, two active-LOW (E1, E2) and one active-HIGH (E3).  
All outputs will be HIGH unless E1 and E2 are LOW and E3  
is HIGH. The LCX138 can be used as an 8-output demulti-  
plexer by using one of the active LOW Enable inputs as the  
data input and the other Enable inputs as strobes. The  
Enable inputs which are not used must be permanently tied  
to their appropriate active-HIGH or active-LOW state.
