MC74HC126ADTR2G-Q

Overview

The MC74HC126ADTR2G-Q is a quad 3-state non-inverting buffer manufactured by onsemi. It operates within a voltage range of 2.0 to 6.0 V and features four separate active-high output enables. The device utilizes high-performance silicon-gate CMOS technology, providing an output drive capability of 15 LSTTL loads. It includes low input current characteristics and high noise immunity. The component is qualified under AEC-Q100 standards and supports PPAP requirements for automotive applications.

Feature Summary

• Features four independent non-inverting buffers with active-high output enables
• Provides direct interface compatibility with CMOS, NMOS, and TTL logic families
• Includes high noise immunity characteristic of CMOS devices
• Complies with JEDEC standard No. 7A requirements

Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented systems

Procurement Notes

Verify the presence of the -Q suffix to confirm AEC-Q100 qualification and PPAP capability. Ensure the ordering code matches the TSSOP-14 package configuration. Confirm RoHS compliance and Pb-free status as specified in the datasheet documentation before finalizing procurement specifications.

Selection Notes

Select this component when active-high output enable control is required for bus management. It serves as a pin-compatible alternative to LS126 devices. Verify that the operating voltage falls within the 2.0 to 6.0 V range. Consider the HC series for broader voltage flexibility compared to HCT variants.

Part Context

This part belongs to the MC74HC126A family of quad 3-state non-inverting buffers. It shares identical pinouts with LS126 equivalents. The -Q suffix indicates specific site and control change requirements suitable for automotive environments. It is distinct from the MC74HC125A which utilizes active-low enables.
