TC7SZ34F,LJ(CT

Overview

The TC7SZ34F,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 push-pull outputs capable of ±24 mA minimum current at 3.0 V. The device supports 5.5 V tolerant inputs and includes power-down protection. It utilizes the SMV (SOT-753) surface-mount package. The specific ordering suffix LJ(CT restricts the operating temperature range to -40°C to +85°C, distinguishing it from other variants in the series that support up to +125°C.

Feature Summary

• Provides non-inverting signal buffering with high output drive capability for reliable logic level translation.
• Incorporates 5.5 V tolerant inputs allowing direct interfacing with higher voltage systems while powered at lower levels.
• Includes power-down protection to prevent excessive leakage current when the device is unpowered.

Applications

• Signal buffering in portable consumer electronics
• Level shifting between different voltage domains in embedded systems
• Clock distribution in low-power digital circuits

Procurement Notes

Verify the part number suffix carefully, as the LJ(CT designation specifies an industrial temperature range (-40°C to +85°C). Ensure compatibility with SMV footprint requirements during PCB layout. Confirm RoHS compliance status with the manufacturer prior to final procurement decisions.

Selection Notes

Select this component for applications requiring a compact, single-channel buffer with moderate drive strength. Consider the restricted temperature range compared to standard commercial variants. Evaluate if the 5.5 V input tolerance meets system interface requirements without additional level shifters.

Part Context

This device belongs to the TC7SZ series of CMOS digital integrated circuits. It serves as a fundamental building block for signal conditioning in modern electronic designs. The SMV package offers a small form factor suitable for space-constrained mobile and handheld devices.

Replacement Considerations

Direct substitutes include TC7SZ34FU,LJ(CT which shares identical electrical characteristics but may differ in packaging or reel specifications. Verify pinout and thermal performance before substitution.
