DM74S153N

Overview

The DM74S153N is a dual 1-of-4 line data selector/multiplexer manufactured by onsemi. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0 °C to +70 °C. The device features two independent four-line sections with common select inputs A and B, and separate strobe inputs for each section. Typical average propagation delay times are 6 ns from data, 9.5 ns from strobe, and 12 ns from select. Power dissipation is typically 225 mW.

Feature Summary

• Performs parallel-to-serial conversion and multiplexing from N lines to 1 line
• Includes inverters and drivers for fully complementary binary decoding
• Features high fan-out, low-impedance, totem-pole outputs
• Provides separate strobe inputs for cascading capabilities

Applications

• Data selection in digital logic circuits
• Parallel-to-serial data conversion systems
• Cascaded multiplexing configurations

Procurement Notes

Verify the component origin as Fairchild Semiconductor, now part of onsemi, due to corporate acquisitions. Confirm the package type matches the 16-Lead Plastic Dual-In-Line (PDIP) specification. Ensure the operating conditions align with the recommended free air temperature range of 0 °C to +70 °C. Check for RoHS compliance status if required for specific manufacturing standards.

Selection Notes

Select this component when a dual 1-of-4 multiplexer with Schottky TTL characteristics is required. Consider the typical propagation delays and power dissipation values for timing and thermal analysis. Verify that the input and output voltage levels match the system requirements. Ensure the PDIP package fits the available board space and assembly methods.

Part Context

This device belongs to the 74S series of logic integrated circuits, known for Schottky technology which provides high speed. The DM74S153N specifically implements dual multiplexer functionality within a single package. It is designed for general-purpose digital applications requiring reliable data routing and selection capabilities.

Replacement Considerations

Direct substitutes may include other 74S153 variants from different manufacturers. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement part meets the same operating temperature and voltage requirements.
