CD74HCT126M96

Overview

The CD74HCT126M96 is a high-speed CMOS logic quad buffer with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. The device utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package, specifically the SOIC-14 variant. It belongs to the HCT logic series, designed for compatibility with TTL inputs while maintaining CMOS low power consumption characteristics.

Feature Summary

• Provides four independent buffers with true output logic functions
• Features three-state outputs for effective bus line driving and isolation
• Constructed using high-speed CMOS technology for low power operation
• Ensures compatibility with standard TTL input levels

Applications

• Bus-oriented architectures requiring signal buffering
• Clock distribution circuits in digital systems
• Data acquisition systems needing signal isolation
• Memory interface drivers for data lines

Procurement Notes

Verify the specific manufacturer source, as this component has been produced by multiple entities including Texas Instruments, Intersil, Renesas, Harris, and Rochester Electronics. Confirm that the datasheet specifications align with the intended application requirements, particularly regarding electrical parameters and thermal performance. Ensure the package type matches the PCB footprint design before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require buffered signals with controllable output states on shared buses. The HCT series ensures direct interfacing with TTL-compatible logic families without additional level shifting. Consider the wide industrial temperature range if the equipment operates in harsh environments. Verify that the 14-pin SOIC package fits the available board space and manufacturing capabilities.

Part Context

This part is a member of the CD74HCT family of high-speed CMOS logic devices. It shares functional similarities with other quad buffers in the series but is distinguished by its specific three-state output configuration. The 'M96' suffix typically denotes a specific tape-and-reel packaging format or manufacturing revision, though exact definitions vary by original manufacturer documentation.

Replacement Considerations

Compatible substitutes include CD74HCT126M, CD74HCT126M96E4, and CD74HCT126M96G4 from Texas Instruments. Other manufacturers such as Renesas and Harris have produced equivalent parts under the same designation. Cross-reference pinouts and electrical characteristics carefully when substituting between different production sources.
