CD74HCT126M96G4

Overview

The CD74HCT126M96G4 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 narrow variant measuring 0.154 inches (3.90 mm) in width. This component belongs to the HCT logic series, ensuring compatibility with standard TTL-driven systems while maintaining low power consumption characteristics typical of CMOS technology.

Feature Summary

• Provides four independent non-inverting buffers with distinct output enable controls for each channel
• Features three-state outputs that allow direct connection to bus-oriented systems without additional pull-up or pull-down resistors
• Designed for high-speed operation compatible with standard TTL input levels

Applications

• Bus-oriented architectures requiring signal buffering and isolation
• Clock distribution networks where controlled drive strength is necessary
• Data acquisition systems utilizing multiplexed signal paths

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to current manufacturer documentation. Confirm the M96 designation aligns with the required tape and reel packaging specifications for automated assembly processes. Cross-reference the full part number against the latest Texas Instruments ordering information to ensure availability and correct manufacturing revision.

Selection Notes

Select this component when interfacing between CMOS logic families and TTL-compatible buses requiring buffered signals. Ensure the system voltage remains strictly within the 4.5 V to 5.5 V operational limits to maintain switching performance. Consider the thermal dissipation capabilities of the SOIC-14 package if multiple channels are actively driving loads simultaneously under maximum temperature conditions.

Part Context

This device is part of the broader CD74HCT family of high-speed CMOS logic integrated circuits produced by Texas Instruments. It shares functional similarities with other quad buffers like the CD74HC126 but offers specific electrical characteristics tailored for HCT logic standards. The M96G4 variant represents a specific manufacturing configuration including packaging and environmental compliance attributes defined by the original equipment manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers include CD74HCT126M96E4 and CD74HCT126M96. Verify pinout compatibility and electrical parameter equivalence before implementation.
