TC7WH34FU,LJ(CT

Overview

The TC7WH34FU,LJ(CT is a triple non-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 3.8 ns at 5.0 V and 15 pF load. The device supports an operating temperature range of -40°C to 85°C, distinguishing it from the standard -40°C to 125°C variant. Key electrical characteristics include a maximum quiescent current of 2.0 µA and high noise immunity defined by minimum input noise voltages of 28% VCC.

Feature Summary

• Triple non-inverter logic function providing three independent buffer channels in a single package.
• High-speed operation capability with balanced low-to-high and high-to-low propagation delays.
• Robust noise immunity ensuring stable signal integrity under dynamic conditions.
• Low power dissipation design suitable for battery-operated or energy-efficient applications.

Applications

• General-purpose buffering and signal conditioning in digital logic circuits.
• Level shifting and interface driving between different logic families.
• Signal routing and distribution in embedded systems requiring isolated non-inverted outputs.

Procurement Notes

Verify that the ordering suffix J(CT) corresponds to the restricted -40°C to 85°C operating temperature range, as opposed to the wider industrial range available in other variants. Confirm package authenticity matches the SM8 (SOT-505) specification. Ensure compliance with RoHS directives and export control classifications before procurement.

Selection Notes

Select this component when a triple non-inverter configuration is required with specific temperature constraints limited to -40°C to 85°C. It serves as a functional and pin-compatible replacement for the TC7W34 series. Consider the 5.5 V tolerant inputs and wide supply voltage range for versatile integration into various power domains.

Part Context

This part belongs to the TC7WH series of L-MOS logic ICs, designed for high-speed and low-power applications. It shares identical pin assignments and functions with the older TC7W34 model, facilitating direct upgrades or replacements in existing designs while offering improved performance metrics such as faster propagation delays.

Replacement Considerations

The TC7WH34FU is functionally and pin-compatible with the TC7W34. Designers replacing legacy components should verify that the application temperature does not exceed 85°C, as the J(CT) suffix restricts the upper limit compared to the standard TC7WH34FU variant which supports up to 125°C.

FAQ

What is the difference in operating temperature between TC7WH34FU and TC7WH34FU,LJ(CT?

The TC7WH34FU,LJ(CT variant has a restricted operating temperature range of -40°C to 85°C. In contrast, the standard TC7WH34FU without the J(CT) suffix supports a wider industrial range of -40°C to 125°C.

Is the TC7WH34FU compatible with the TC7W34?

Yes, the TC7WH34FU has identical pin assignments and logical functions to the TC7W34, allowing for direct substitution in most designs while providing enhanced speed and lower power consumption.
