TC7SH34FU(T5L,F,T)

Overview

The TC7SH34FU(T5L,F,T) is a single-channel non-inverting buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 2.0 V to 5.5 V and features 5.5 V tolerant inputs. The device supports high-speed operation with a typical propagation delay of 3.8 ns at 5.0 V and 15 pF load. Quiescent supply current is limited to a maximum of 2.0 µA at 25 °C. Input leakage current remains within ±0.1 µA under standard conditions. The component utilizes a USV (SOT-353) surface-mount package.

Feature Summary

• Compliant with AEC-Q100 reliability standards for automotive applications
• Features wide operating temperature range extending up to 125 °C
• Provides high noise immunity with defined input thresholds relative to supply voltage
• Supports 5.5 V tolerant inputs for interfacing with various logic families

Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• General-purpose signal buffering in digital circuits
• Level shifting between different voltage domains
• High-speed data line buffering in consumer electronics

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range, as devices ending in J(CT) are rated for -40 °C to 85 °C, while others support -40 °C to 125 °C. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Confirm package type matches design constraints. Check latest datasheet revisions for any updates to electrical characteristics or marking information before finalizing procurement specifications.

Selection Notes

Select this component when a single non-inverting buffer with high-speed performance and wide voltage tolerance is required. The 5.5 V input tolerance allows direct interfacing with 5 V logic even at lower supply voltages. Consider the extended temperature range capability for harsh environments. Verify that the low quiescent current meets power consumption targets. Ensure the SOT-353 package fits the available PCB space.

Part Context

This part belongs to the TC7SH series of CMOS digital integrated circuits from Toshiba. The series focuses on high-speed, low-power logic functions suitable for portable and automotive applications. The TC7SH34FU specifically provides a single non-inverting buffer function. It shares functional similarities with other buffers in the family but offers specific electrical characteristics tailored for robust signal integrity across varying supply voltages.

Replacement Considerations

Check for pin-compatible alternatives within the Toshiba TC7SH series. Verify that any substitute maintains the same input voltage tolerance and propagation delay specifications. Ensure the replacement part meets the required operating temperature range and AEC-Q100 compliance if applicable. Confirm package dimensions match the existing footprint.
