TC7WH34FU(TE12L)

Overview

The TC7WH34FU(TE12L) is a CMOS digital integrated circuit featuring three non-inverter gates. 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 provides high-speed operation with a typical propagation delay of 3.8 ns at 5.0 V and low power dissipation with a maximum quiescent current of 2.0 µA. Inputs are tolerant up to 5.5 V, ensuring compatibility with various logic families.

Feature Summary

• High-speed signal processing with balanced propagation delays
• Low power consumption suitable for battery-operated applications
• Wide operating temperature range extending to 125°C
• 5.5 V tolerant inputs for flexible interfacing

Applications

• General-purpose logic buffering and inversion
• Signal routing in mixed-voltage systems
• Data bus isolation and driving

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range. Devices ending in J(CT) support -40°C to 85°C, while other suffixes support -40°C to 125°C. Ensure the package type matches the SM8 (SOT-505) specification. Confirm RoHS compliance status with the supplier prior to purchase.

Selection Notes

Select this component when three independent non-inverting buffers are required in a compact surface-mount package. It is suitable for designs needing wide temperature tolerance and 5.5 V input compatibility. Consider the SM8 package dimensions for PCB layout constraints. Verify that the load capacitance requirements align with the specified propagation delay characteristics.

Part Context
