TC7WH126FK,LJ

Overview

The TC7WH126FK,LJ is a dual bus buffer with 3-state outputs manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 to 5.5 V and features balanced propagation delays. The device supports high-speed operation with a typical propagation delay of 3.8 ns at 5.0 V. It includes 5.5 V tolerant inputs and offers low power dissipation with a maximum quiescent current of 2.0 µA. The component complies with AEC-Q100 reliability requirements and is available in the US8 package.

Feature Summary

• Dual bus buffer architecture with 3-state output capability
• Compliance with AEC-Q100 reliability standards for automotive applications
• Wide operating temperature range extending up to 125 °C
• High noise immunity with 5.5 V tolerant inputs

Applications

• Automotive electronic systems requiring high reliability
• High-speed data buffering in consumer electronics
• Industrial control systems operating under wide temperature conditions

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range, as devices ending in J(CT) are rated for -40 to 85 °C while others support -40 to 125 °C. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure that the selected package variant matches the PCB footprint requirements for the US8 housing.

Selection Notes

Select this component when a dual-channel buffer with 3-state control is required for signal isolation or level shifting. The 5.5 V input tolerance allows interfacing with higher voltage logic levels without external protection. Consider the balanced propagation delays for timing-sensitive applications. Verify that the load capacitance and supply voltage align with the specified AC characteristics for the desired performance.

Part Context

This part belongs to the TC7WH series of CMOS digital integrated circuits from Toshiba. The series focuses on low power consumption and high-speed operation suitable for modern portable and automotive electronics. The TC7WH126 specifically provides dual buffering functionality, distinguishing it from single-channel buffers or inverters within the same family.

Replacement Considerations

Consult official Toshiba documentation for confirmed substitute part numbers. Cross-referencing with other manufacturers requires careful verification of pin compatibility, electrical parameters, and package dimensions to ensure functional equivalence.
