TC7W34FK(TE85L)

Overview

The TC7W34FK(TE85L) is a triple non-inverter buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 V to 6.0 V and features high-speed performance with a typical propagation delay of 6 ns at 5 V. The device provides symmetrical output impedance with a minimum drive capability of 4 mA and supports up to 10 LSTTL loads. It exhibits low power dissipation, drawing a maximum quiescent current of 1 μA at 25°C. The component is housed in an SSOP-8 package (US8) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Triple non-inverting logic configuration
• High noise immunity with defined input thresholds
• Low power consumption design
• Symmetrical output drive characteristics

Applications

• General-purpose digital signal buffering
• Line driver applications for logic signals
• Signal isolation in mixed-voltage systems

Procurement Notes

Verify the specific ordering suffix TE85L against the manufacturer's latest documentation to confirm packaging details such as reel size or tape specifications. Confirm RoHS compliance status directly with the supplier or through official datasheets prior to procurement. Ensure the SSOP-8 footprint matches the target PCB layout requirements.

Selection Notes

Select this component when a triple non-inverting buffer is required for low-power digital circuits. The wide operating voltage range allows compatibility with various logic families. Verify that the required propagation delay meets the system timing constraints, particularly under different load capacitance conditions.

Part Context

This part belongs to the TC7W series of CMOS digital integrated circuits from Toshiba. The series includes various logic gates and buffers designed for general-purpose applications. The FK variant specifically denotes the US8 surface-mount package type, distinguishing it from other physical form factors available within the same logical family.

Replacement Considerations

Check for direct substitutes within the TC7W series or equivalent parts from other manufacturers offering triple non-inverters in SSOP-8 packages. Ensure replacement components match the electrical characteristics, specifically the 2V to 6V operating range and propagation delays.
