The F139 is a high-speed, dual 1-of-4 decoder/demultiplexer. It 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-out- put demultiplexer. Each half of the F139 can be used as a function generator providing all four minterms of two vari- ables.
The document describes the F139, a high-speed integrated circuit featuring two independent decoders. Each decoder accepts two binary weighted inputs and provides four mutually exclusive active LOW outputs. The enable input can function as a data input for demultiplexing applications.
The datasheet includes logic symbols, connection diagrams, truth tables, and gate function descriptions. It also details absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, and physical dimensions for three available package types: SOIC (M16A), SOP (M16D), and PDIP (N16E).
