MC74AC138, MC74ACT138  
1−of−8  
Decoder/Demultiplexer  
The MC74AC138/74ACT138 is a highspeed 1of8  
decoder/demultiplexer. This device is ideally suited for highspeed  
bipolar memory chip select address decoding.  
The multiple input enables allow parallel expansion to a 1of24  
decoder using just three MC74AC138/74ACT138 devices or a  
1of32decoder using four MC74AC138/74ACT138 devices and one  
inverter.
