Descriptions
Descriptions of onsemi 74F139SCX provided by its distributors.
2-LINE TO 4-LINE DECODER, F/FAST Series, Inverted Output, TTL, PDSO16
Decoder/Demultiplexer Dual 2-to-4 16-Pin SOIC N T/R
74F139 1x 2:4 2000 74F decoder circuit 9ns 5.5V 1mA 20mA 0C~70C
DECODER/DEMUX DUAL 1-OF-4 16SOIC
ADV SCHOTTKY DUAL 1/4 DECODE/D
The F139 is a high-speed, dual 1-of-4 decoder/demulti-plexer. 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 a4-output demultiplexer. Each half of the F139 can be used as a function generator providing all four minterms of two variables.
