SN54/74LS138  
1-OF-8 DECODER/  
DEMULTIPLEXER  
The LSTTL/MSI SN54/74LS138 is a high speed 1-of-8 Decoder/  
Demultiplexer. This device is ideally suited for high speed bipolar memory  
chip select address decoding. The multiple input enables allow parallel ex-  
pansion to a 1-of-24 decoder using just three LS138 devices or to a 1-of-32  
decoder using four LS138s and one inverter. The LS138 is fabricated with the  
Schottky barrier diode process for high speed and is completely compatible  
with all Motorola TTL families.
