MC74F538 Datasheet

1-of-8 Decoder With 3-state Outputs

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

MC74F538 Overview

A polarity control input (P) determines whether the outputs are active LOW or active HIGH. A HIGH Signal on either of the active LOW Output Enable (OE) inputs forces all outputs to the high impedance state. Two active HIGH and two active LOW input enables are available for easy expansion to 1-of-32 decoding with four packages, or for data demultiplexing to 1-of-8 or 1-of-16 destinations.
