DESCRIPTION  
The M54/74HC138 is a high speed CMOS 3 TO 8  
LINE DECODER fabricated in silicon gate C2MOS  
technology.  
PIN CONNECTIONS (top view)  
It has the same high speed performance of LSTTL  
combined with true CMOS low power consumption.  
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 high.  
Three enable inputs are provided to ease cascade  
connection and application of address decoders for  
memory systems. All inputs are equipped with pro-  
tection circuits against static discharge and tran-  
sient excess voltage.
