SN74F153D

Overview

The SN74F153D is a dual 1-of-4 data selector/multiplexer from the Texas Instruments F/FAST logic series. It integrates two independent multiplexers within a single 16-pin SOIC package. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V. It supports four inputs per multiplexer and provides true outputs. The component is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates two independent 4-to-1 multiplexers in a compact package
• Provides true output signals for direct interfacing
• Compatible with standard TTL logic families

Applications

• Data routing in digital systems
• Address decoding circuits
• Sequential control logic

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC surface-mount package and commercial temperature grade. Confirm RoHS compliance status via the manufacturer's current documentation, as manufacturing processes may update environmental declarations over time. Ensure the ordering part number matches the required pin configuration and lead finish specifications.

Selection Notes

Select this component when dual independent multiplexing is required within the F/FAST speed class. Verify that the 4.5 V to 5.5 V supply range aligns with the system power rails. Consider the 16-pin SOIC footprint for PCB layout constraints. Compare propagation delays against system timing requirements if high-speed switching is critical.

Part Context

This device belongs to the 74F series, known for high-speed performance compared to standard 74LS logic. It serves as a functional equivalent to other industry-standard dual 4-to-1 multiplexers. The SN74F153D is designed for general-purpose digital applications requiring reliable signal selection and routing capabilities.

Replacement Considerations

Check for SN74F153DRG4 or SN74F153DR as potential variants offering identical functionality with different packaging or environmental certifications. Verify pin compatibility before substitution.
