TC7WH34FK(TE85L)

Overview

The TC7WH34FK(TE85L) is a triple non-inverting buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2V to 5.5V and supports high output currents of 8mA for both high and low states. The device features a propagation delay of 9.3ns at 5V with a 50pF load, ensuring fast signal transmission. It includes 5.5V tolerant inputs and provides power-down protection for outputs. The component is housed in an 8-VFSOP package with a width of 2.30mm and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Triple non-inverting buffer configuration
• High output drive capability
• 5.5V tolerant input structure
• Power-down protection for outputs

Applications

• General-purpose digital signal buffering
• Level shifting between logic families
• Clock distribution networks

Procurement Notes

Verify the specific ordering suffix (TE85L) against the manufacturer's current datasheet to confirm packaging type and reel specifications. Ensure the component designation matches the exact part number required for your bill of materials, as variations may exist within the same logical family. Cross-reference the manufacturer code with official Toshiba Semiconductor and Storage documentation to validate authenticity and production status before procurement.

Selection Notes

Select this component when a triple buffer with high drive strength is required for signals operating up to 5.5V. The 8mA output current makes it suitable for driving moderate capacitive loads or multiple inputs. Consider the 8-VFSOP package dimensions for PCB layout constraints. Verify that the 9.3ns propagation delay meets the timing requirements of the target application circuit.

Part Context

This part belongs to the TC7WH series of L-MOS logic ICs from Toshiba Semiconductor and Storage. The series is characterized by high-speed operation and robust input tolerance. The TC7WH34 specifically provides three independent buffer channels in a compact surface-mount package, designed for applications requiring signal integrity and noise immunity in mixed-voltage systems.

Replacement Considerations

Check for direct substitutes within the TC7WH series or compatible L-MOS logic families from Toshiba. Verify pin compatibility and electrical parameters such as output current and propagation delay. Ensure any replacement maintains the 5.5V input tolerance and package footprint.
