SN74F153DR

Overview

The SN74F153DR is a dual 1-of-4 data selector/multiplexer from Texas Instruments, belonging to the 74F logic family. It integrates two independent multiplexers within a single 16-pin SOIC package. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0 °C to 70 °C. Each multiplexer features four data inputs, two select lines, and one enable input, providing a high-speed bipolar solution for digital signal routing applications.

Feature Summary

• Integrates two independent 4-line to 1-line data selectors in a compact surface-mount package
• Utilizes high-speed bipolar (74F) technology for rapid signal switching
• Includes dedicated enable inputs for precise control over data path activation

Applications

• Digital data routing and selection circuits
• Address decoding systems
• Parallel-to-serial data conversion interfaces

Procurement Notes

Verify the specific suffix 'DR' confirms the tape-and-reel packaging format and standard commercial grade temperature rating. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the ordering part number matches the exact pinout and electrical specifications required by the design.

Selection Notes

Select this component when high-speed switching performance is required compared to standard 74 series logic. The dual configuration reduces board space compared to using separate single multiplexers. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power rails and that the bipolar technology characteristics fit the noise immunity requirements.

Part Context

This part belongs to the Texas Instruments 74F series, known for fast propagation delays. The SN74F153 provides dual multiplexing capabilities, contrasting with single-channel variants like the SN74F151. It serves as a core building block for complex digital logic designs requiring efficient data path management within industrial and commercial electronic systems.
