TC7SZ34FE,LM

Overview

The TC7SZ34FE,LM is a single-channel non-inverting Schmitt trigger buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.65 V to 5.5 V and features push-pull outputs capable of sourcing -32 mA and sinking 32 mA. The device exhibits a maximum propagation delay of 11 ns at 15 pF load and consumes a typical static current of 2 µA. It is designed for surface-mount installation in an SOT-553 package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates Schmitt trigger input characteristics to provide noise immunity and clean signal transitions.
• Features push-pull output stage architecture for robust drive capability.
• Supports low-voltage operation starting at 1.65 V for compatibility with modern logic families.

Applications

• Signal buffering in portable electronic devices
• Clock signal conditioning and distribution
• Noise filtering for digital input lines

Procurement Notes

Verify the specific suffix 'LM' against the manufacturer's official datasheet to confirm pinout and electrical specifications match project requirements. Ensure the component meets AEC-Q100 automotive qualification standards if the application demands such reliability. Cross-reference the RoHS compliance status with the latest environmental declarations before finalizing procurement.

Selection Notes

Select this component when a single-channel buffer with hysteresis is required for noisy environments. The wide supply voltage range allows flexibility in system design across different power rails. Consider the SOT-553 package size for space-constrained printed circuit board layouts requiring minimal footprint.

Part Context
