TC7SH34FU,LJ(CT

Overview

The TC7SH34FU,LJ(CT is a single-channel non-inverting buffer from Toshiba's SH series, housed in a USV (SOT-353) package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature range of -40°C to 85°C for this specific suffix. Key electrical parameters include a typical propagation delay of 3.8 ns at 5.0 V with a 15 pF load, a maximum quiescent current of 2.0 µA at 25°C, and high noise immunity defined as 28% of VCC minimum.

Feature Summary

• Provides non-inverting buffering functionality for digital signals.
• Features high-speed operation with low propagation delay characteristics.
• Designed for low power consumption with minimal quiescent current draw.
• Includes robust noise immunity suitable for noisy environments.

Applications

• Signal buffering in automotive electronic control units.
• Level shifting and signal conditioning in consumer electronics.
• Interface buffering between logic families in industrial equipment.

Procurement Notes

Verify the ordering suffix J(CT) confirms the -40°C to 85°C operating temperature range, distinct from the wider -40°C to 125°C range available for other suffixes. Confirm AEC-Q100 compliance requirements if automotive qualification documentation is needed directly from Toshiba sales representatives. Ensure input pins are tied to VCC or GND when unused to maintain normal operation.

Selection Notes

Select this component for applications requiring a single-channel non-inverting buffer with wide voltage tolerance up to 5.5 V. The USV package offers a compact footprint for space-constrained designs. Consider the specific temperature rating associated with the LJ(CT) suffix versus standard variants when designing for extreme environmental conditions.

Part Context

This device belongs to Toshiba's CMOS Digital Integrated Circuits Silicon Monolithic family, specifically the SH series. Commercial production began in April 2004. It is part of a broader lineup of L-MOS logic gates and buffers designed for general-purpose digital applications requiring high speed and low power dissipation.
