TC7WH125FK,LJ(CT

Overview

The TC7WH125FK,LJ(CT 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 V to 5.5 V and features 5.5 V tolerant inputs. The device supports a wide operating temperature range of -40°C to 85°C. Key electrical characteristics include a maximum quiescent supply current of 2.0 µA at 25°C and a typical propagation delay of 3.8 ns at 5.0 V with a 15 pF load. It complies with AEC-Q100 reliability standards.

Feature Summary

• Dual bus buffer architecture with non-inverting logic and 3-state output control
• High-speed operation capability with low propagation delay times
• Low power dissipation design with minimal quiescent current consumption
• Robust noise immunity and low output noise voltage characteristics

Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• General-purpose data bus buffering applications
• Signal isolation between different voltage domains
• High-speed digital circuit interfacing

Procurement Notes

Verify the specific ordering suffix J(CT) to confirm the operating temperature range is limited to -40°C to 85°C, as other suffixes may support up to 125°C. Ensure compatibility with US8 (SOT-765) surface-mount packaging requirements during PCB layout. Confirm that input pins are tied to VCC or GND when unused to prevent floating states. Check for RoHS compliance status through official Toshiba channels before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring dual-channel buffering with 3-state functionality in a compact US8 package. It is suitable for automotive applications due to its AEC-Q100 qualification. Consider the 5.5 V input tolerance for interfacing with higher voltage logic levels while operating at lower supply voltages. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity across the operating temperature range.

Part Context

This part belongs to the TC7WH series of CMOS digital integrated circuits from Toshiba. It is functionally similar to other dual bus buffers but distinguished by its specific AEC-Q100 automotive qualification and 5.5 V tolerant input structure. The US8 package provides a small footprint suitable for space-constrained designs. It serves as a silicon monolithic solution for high-speed, low-power buffering tasks.

Replacement Considerations

Direct substitutes include the TC7WZ125FK,LJ(CT, which offers similar buffering functions but may differ in specific electrical parameters or package availability. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength before substitution. Ensure the replacement part meets the same AEC-Q100 requirements if used in automotive contexts.
