The 74LCX138 is a low voltage CMOS 3 to 8 line  
decoder (inverting) fabricated with sub-micron  
silicon gate and double-layer metal wiring C MOS  
technology. It is ideal for low power and high  
speed 3.3V applications; it can be interfaced to  
5V signal environment for inputs.

74 series 138  
Latch-up performance exceeds  
If the device is enabled, 3 binary select inputs (A,  
B and C) determine which one of the outputs will  
go low. If enable input G1 is held low or either  
G2A or G2B is held high, the decoding function is  
inhibited and all the 8 outputs go to high.  
500mA (JESD 17)  
ESD performance:  
– HBM > 2000V  
(MIL STD 883 method 3015); MM > 200V  
Three enable inputs are provided to ease  
cascade connection and application of address  
decoders for memory systems.  
It has same speed performance at 3.3V than 5V  
AC/ACT family, combined with a lower power  
consumption.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.
