HD74AC539 Product details

Description

The HD74AC539 contains two inpedendent decoders.

Each accepts two Address (A 0, A1) input signals and decodes them to select one of four mutually exclusive outputs.

A polarity control input (P) determines whether the outputs are active HIGH (P = L) or active LOW (P = H).
