TC7WH125FK

Overview

The TC7WH125FK 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 supports an operating temperature range from -40°C to 125°C. The device features high-speed operation with a typical propagation delay of 3.8 ns at 5.0 V. It includes 5.5 V tolerant inputs, low power dissipation with a maximum quiescent current of 2.0 µA, and high noise immunity. The component is packaged in the US8 (SOT-765) surface-mount format.

Feature Summary

• Dual bus buffer configuration with non-inverting logic and 3-state output capability
• Wide operating voltage range supporting 2.0 V to 5.5 V supply levels
• Extended industrial temperature rating spanning -40°C to 125°C
• High noise immunity with defined dynamic input voltage thresholds

Applications

• Bus-oriented memory and address drivers
• Clock buffering and distribution circuits
• High-speed data transmission line drivers

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range, as devices ending in J(CT) are rated for -40°C to 85°C while others support -40°C to 125°C. Confirm AEC-Q100 compliance requirements if automotive qualification is necessary for the target application environment.

Selection Notes

Select this component when a dual-channel buffer with 3-state control is required for systems operating between 2.0 V and 5.5 V. The wide temperature range makes it suitable for demanding industrial environments. Ensure input signals remain within the specified voltage limits to maintain proper logic threshold performance.

Part Context

This part belongs to the TC7WH series of CMOS digital integrated circuits produced by Toshiba. The series focuses on high-speed, low-power logic functions designed for modern electronic applications requiring reliable signal buffering and driving capabilities across varying voltage and temperature conditions.

Replacement Considerations

Direct substitutes include TC7WH125FUTE12LF and TC7WH125FU,LF. Verify pin compatibility and electrical specifications before substitution.
