DM74LS153N

Overview

The DM74LS153N is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi in a 16-lead Plastic Dual-In-Line (PDIP) package. It integrates inverters and drivers for binary decoding to AND-OR-invert gates, featuring separate strobe inputs for each section. Common select inputs A and B control both sections. Recommended operating conditions specify a supply voltage of 4.75V to 5.25V and an operating temperature range of 0°C to +70°C. Typical propagation delays are 14ns from data, 19ns from strobe, and 22ns from select.

Feature Summary

• Performs parallel-to-serial conversion
• Provides high fan-out, low impedance, totem pole outputs
• Includes strobe lines for cascading N lines to n lines

Applications

• Multiplexing from N lines to 1 line
• Parallel-to-serial data conversion
• Cascading configurations for expanded multiplexing

Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and reel options. The 'N' designation indicates a PDIP package; ensure compatibility with existing PCB footprints. Confirm availability status as this component may be subject to lifecycle changes or obsolescence notices.

Selection Notes

Select this component when dual independent 4-line multiplexing is required within a single package. Ensure the application operates within the 0°C to +70°C temperature range and utilizes a 5V logic supply. Verify that the TTL-compatible input levels meet system requirements for HIGH and LOW voltage thresholds.

Part Context

This device belongs to the 74LS series of logic integrated circuits, designed for Low-power Schottky applications. It serves as a standard digital logic component for data routing and selection tasks in general-purpose electronic systems requiring reliable switching performance.

Replacement Considerations

Compatible substitutes include SN74LS153N and MC74LS153N. Verify pinout compatibility and electrical characteristics match before integration.
