MC74HC126ADR2G

Overview

The MC74HC126ADR2G is a quad bus buffer manufactured by onsemi, belonging to the HC logic series. It features four independent non-inverting buffers with three-state control inputs in a 16-pin SOIC package. The device operates within a supply voltage range of 2.0 V to 6.0 V. Key electrical parameters include a propagation delay of 110 ns, high-level output current of -5.2 mA, and low-level output current of 5.2 mA. It supports surface mount installation and functions across an operating temperature range from -55°C to +125°C.

Feature Summary

• Provides four independent non-inverting buffers with three-state control for flexible signal routing
• Compatible with standard CMOS outputs and LSTTL loads via pull-up resistors
• Offers high noise immunity meeting JEDEC standards for stable operation in noisy environments
• Designed for wide voltage adaptation suitable for various power supply conditions

Applications

• Three-state memory address drivers
• Clock drivers in digital systems
• Bus-oriented system architectures requiring signal isolation

Procurement Notes

Verify the specific suffix ADR2G corresponds to the SOIC-16 package and reel packaging configuration. Confirm RoHS compliance and lead-free status as per manufacturer specifications. Ensure the ordering part number matches the exact logic family (HC) and pinout requirements for your design. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required. The HC series offers compatibility with standard CMOS logic levels. Consider the 2.0 V to 6.0 V operating range for flexibility in power supply design. The SOIC-16 package is suitable for surface mount applications requiring moderate pin density. Verify thermal performance within the specified -55°C to +125°C range for your environment.

Part Context

This component is part of onsemi's extensive portfolio of high-speed CMOS logic integrated circuits. The MC74HC126A variant specifically addresses needs for bus buffering and signal direction control. It belongs to the broader 74HC family, known for balancing speed and power consumption. The device serves as a fundamental building block for digital interface circuits and data transmission lines.

Replacement Considerations

Check for direct pin-compatible substitutes such as MC74HCT126ADR2G if TTL input compatibility is needed instead of CMOS. Verify equivalent packages like TSSOP-16 if space constraints differ. Ensure logical function remains identical with non-inverting quad buffers featuring three-state controls.
