SN74F253DRG4

Overview

The SN74F253DRG4 is a quad multiplexer from the Texas Instruments 74F series, featuring two independent 4-to-1 data selectors. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 16-SOIC package. The device provides high-speed signal routing with a propagation delay of 7 ns at 5 V. It functions reliably across an industrial temperature range from 0°C to +70°C, ensuring stable performance for digital logic applications requiring efficient data selection.

Feature Summary

• Integrates two independent 4-to-1 multiplexers within a single package
• Provides high-speed data selection capabilities suitable for fast digital systems
• Features three-state outputs for effective bus line driving and isolation

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Signal switching in test and measurement equipment

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green manufacturing status. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm that the operating voltage remains strictly within the 4.5 V to 5.5 V range to prevent device damage or malfunction during operation.

Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required in a compact surface-mount form factor. The 74F series offers faster switching speeds compared to standard 74LS counterparts but consumes more power. Verify that the system can accommodate the higher current draw typical of the F series while maintaining the specified voltage supply stability.

Part Context

This component belongs to the SN74F family of high-speed CMOS logic devices manufactured by Texas Instruments. The 'G4' suffix indicates compliance with RoHS standards and general environmental protection requirements. It serves as a specialized variant within the broader 74F multiplexer lineup, designed for applications demanding rapid data path selection in dense electronic assemblies.

Replacement Considerations

SN74F253DRE4 is a verified equivalent part number offering identical electrical characteristics and functionality.
