DM74ALS151MX

Overview

The DM74ALS151MX is a 1-of-8 line data selector/multiplexer manufactured by onsemi in a 16-lead SOIC package. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial temperature range of 0°C to +70°C. The device features complementary Y and W outputs with propagation delays ranging from 3ns to 24ns depending on the signal path. It includes full on-chip decoding for three-bit binary selection and utilizes an Advanced Schottky TTL process.

Feature Summary

• Provides full on-chip decoding to select one of eight data sources based on a unique three-bit binary code at the Select inputs.
• Features two complementary outputs that provide both inverting and non-inverting buffer operation simultaneously.
• Includes a Strobe input that disables all data inputs when high, forcing the Y output low and the W output high.
• Incorporates internal overlap features in the Select input buffers to prevent invalid output transients during state changes.

Applications

• High-performance memory-decoding systems
• Data-routing applications requiring multiplexing
• Digital logic circuits requiring parallel-to-serial conversion
