TC7SH34FS(TPL3)

Overview

The TC7SH34FS(TPL3) is a single non-inverting buffer from Toshiba's L-MOS SHS series, designed for low-voltage portable applications. It operates within a supply voltage range of 0.9 V to 3.6 V and features input tolerance compatible with 5-V systems. The device utilizes the SOT-953 (fSV) surface-mount package, measuring 1.0 mm x 1.0 mm x 0.48 mm with five pins. It provides high-speed signal buffering while maintaining low power consumption, making it suitable for battery-powered devices requiring level shifting between different logic families.

Feature Summary

• L-MOS technology enables operation at ultra-low voltages down to 0.9 V.
• Input pins are tolerant to 5-V signals, allowing direct interfacing with higher voltage logic.
• Compact SOT-953 package supports dense PCB layouts in space-constrained designs.

Applications

• Level shifting buffers between 1.8-V or 3.3-V logic and 5-V interfaces
• Signal buffering in mobile phones and handheld devices
• Portable equipment requiring low-power signal transmission

Procurement Notes

Verify the exact suffix (TPL3) against the manufacturer datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the required RoHS compliance status. Cross-reference the SOT-953 footprint dimensions with your PCB design library before finalizing procurement to avoid assembly errors.

Selection Notes

Select this component when a single-channel non-inverting buffer is needed for low-voltage logic conversion. It is appropriate for designs requiring 5-V input tolerance with a 3.6-V maximum supply. Consider the SOT-953 package size constraints and thermal requirements relative to other L-MOS buffers in the Toshiba portfolio.

Part Context

This part belongs to Toshiba's L-MOS SHS series, which offers performance comparable to industry-standard HCX logic but optimized for lower voltage operation. The series focuses on reducing power consumption in portable electronics while maintaining signal integrity across varying supply conditions.

Replacement Considerations

Check for direct equivalents such as the TC7SZ34AFS or 7UL1G34FS,LF, ensuring pin compatibility and electrical characteristics match the specific application requirements.
