TC7SZ34FU,LJ(CT

Overview

The TC7SZ34FU,LJ(CT is a single-channel non-inverting buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.65 V to 5.5 V and features 5.5 V tolerant inputs with power-down protection outputs. The device supports an operating temperature range of -40°C to 85°C. Key electrical parameters include a typical propagation delay of 2.4 ns at 5.0 V, high output current capability of ±24 mA minimum at 3.0 V, and low quiescent supply current.

Feature Summary

• Provides 5.5 V tolerant input levels for compatibility with higher voltage logic interfaces.
• Includes power-down protection on the output to prevent leakage during low-power states.
• Delivers high drive strength suitable for loading demanding bus lines or capacitive loads.

Applications

• Clock signal buffering in portable electronic devices
• Level shifting between different voltage domains
• Driving external loads in automotive infotainment systems

Procurement Notes

Verify that the specific ordering suffix matches the required thermal grade, as the J(CT) designation indicates a restricted operating temperature range compared to standard variants. Confirm AEC-Q100 compliance requirements if the application targets automotive reliability standards. Ensure the package type aligns with the PCB footprint design constraints.

Selection Notes

Select this component when a single-channel non-inverting buffer is required with wide voltage flexibility. It is appropriate for designs needing 5.5 V tolerance without additional level-shifting circuitry. Consider the propagation delay specifications against the system timing budget to ensure signal integrity is maintained across the full operating temperature range.

Part Context

This part belongs to the TC7SZ series of CMOS digital integrated circuits from Toshiba. The series focuses on small-package solutions for portable applications. The USV (SOT-353) package provides a compact form factor suitable for space-constrained printed circuit board layouts.

Replacement Considerations

Check for direct equivalents within the same manufacturer's portfolio that may offer extended temperature ranges or alternative packaging options while maintaining identical pinouts and logical functions.
