DUAL 1-OF-4 DECODER/
DEMULTIPLEXER
The LSTTL/MSI SN54/74LS139 is a high speed Dual 1-of-4 Decoder/De-
multiplexer. The device has two independent decoders, each accepting two
inputs and providing four mutually exclusive active LOW Outputs. Each
decoder has an active LOW Enable input which can be used as a data input
for a 4-output demultiplexer. Each half of the LS139 can be used as a function
generator providing all four minterms of two variables. The LS139 is
fabricated with the Schottky barrier diode process for high speed and is
completely compatible with all Motorola TTL families.
