74F5381-of-8 decoder (3-State)

DESCRIPTION

PIN CONFIGURATION

The 74F538 decoder/demultiplexer accepts three address (A0 - A2) input signals and decodes them to select one of eight mutually exclusive outputs. A Polarity control (P) input determines whether the outputs are active Low or active High. The 74F538 has 3-State outputs, and a High signal on the Output Enables (OE
n) inputs will force all outputs to the high impedance state. Two active High (E2, E3) and two active Low (E
0, E1) inputs 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.

Definitions

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook. Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
