TC7WH125FU,LJ(CT

Overview

The TC7WH125FU,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 supports inputs tolerant up to 5.5 V. The device features low power dissipation with a maximum quiescent current of 2.0 µA at 25 °C. Propagation delay is typically 3.8 ns at 5.0 V with a 15 pF load. The ordering suffix J(CT) restricts the operating temperature range to -40 °C to 85 °C, while other variants support -40 °C to 125 °C. It is housed in an SM8 (SOT-505) package.

Feature Summary

• Dual bus buffer architecture with independent 3-state control for each channel
• High noise immunity with defined dynamic input voltage limits
• Low noise performance characterized by quiet output maximum dynamic VOL
• Wide operating voltage range compatible with standard logic families

Applications

• Data bus buffering in high-speed digital systems
• Voltage level translation between different logic domains
• Signal isolation in communication interfaces

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range, as the J(CT) suffix indicates a restricted range of -40 °C to 85 °C compared to the wider range available for other suffixes. Ensure compatibility with the required supply voltage and check for RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component when a dual-channel buffer with 3-state capability is required for bus applications. Consider the propagation delay characteristics relative to system clock speeds and ensure the input voltage levels match the source logic family. Verify that the SM8 package dimensions fit the PCB layout constraints and that the thermal requirements align with the specified power dissipation limits under expected operating conditions.

Part Context

This part belongs to the TC7WH series of CMOS digital integrated circuits from Toshiba. The series focuses on wide voltage operation and low power consumption. The TC7WH125 specifically provides dual buffering functionality, distinguishing it from single-channel buffers or inverters within the same product family. It utilizes silicon monolithic technology for robust performance across industrial temperature ranges.

Replacement Considerations

Check for direct pin-compatible alternatives within the Toshiba TC7WH series, such as the TC7WH126, which offers similar buffering but may differ in specific electrical characteristics or package options. Verify functional equivalence regarding 3-state control and voltage tolerance before substituting.
