TC7WHU04FK,LJ(CT

Inverter Gates Overview

The TC7WHU04FK is a triple inverter CMOS digital integrated circuit manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 V to 5.5 V and features balanced propagation delays with a typical value of 3.5 ns at 5.0 V. The device supports high-speed operation, low power dissipation with a maximum quiescent current of 2.0 µA, and high noise immunity. Inputs are tolerant up to 5.5 V. The component is available in the US8 package (SOT-765).

Inverter Gates Feature Summary

• Compliant with AEC-Q100 reliability requirements.
• Features wide operating temperature ranges extending to 125 °C for standard versions or 85 °C for J(CT) suffix variants.
• Provides high noise immunity with minimum input noise voltages defined as 10% of VCC.

Inverter Gates Applications

• Automotive electronic systems requiring AEC-Q100 compliance.
• High-speed signal inversion in digital logic circuits.

Inverter Gates Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range. Devices ending in J(CT) operate between -40 °C and 85 °C, while other suffixes support -40 °C to 125 °C. Confirm package type US8 availability and ensure design adherence to absolute maximum ratings to prevent performance deterioration.

Inverter Gates Selection Notes

Select this component when AEC-Q100 automotive qualification is required alongside high-speed inverting functions. The 5.5 V tolerant inputs allow interfacing with various logic levels without level shifting. Ensure the application utilizes the US8 package constraints and verify that the extended temperature range matches the environmental conditions of the target system.

Inverter Gates Part Context

This part belongs to the TC7WH series of L-MOS logic ICs from Toshiba. It serves as an unbuffered triple inverter designed for general-purpose digital applications. The series emphasizes low power consumption and high speed, making it suitable for modern embedded systems where efficiency and signal integrity are critical.

Inverter Gates Replacement Considerations

The datasheet notes identical pin assignment and function with the TC7WU04. Verify if the legacy TC7WU04 meets the specific AEC-Q100 and temperature range requirements before substitution.

Inverter Gates FAQ

What is the difference in operating temperature between the standard TC7WHU04FK and the TC7WHU04FK,LJ(CT variant?

Devices with the ordering part number ending in J(CT) have an operating temperature range of -40 °C to 85 °C. Other devices in the series support a wider range of -40 °C to 125 °C.

How does the TC7WHU04FK handle unused inputs?

Unused inputs must be tied to either VCC or GND to ensure normal operation and prevent undefined states.
