TC7SZ125FU,LJ(CT

Overview

The TC7SZ125FU,LJ(CT is a single-channel bus buffer with three-state outputs 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 alongside power-down protection. The device utilizes an SMV (SOT-753) package. For the specific ordering suffix J(CT), the operating temperature range is restricted to -40 °C to 85 °C, while other variants support up to 125 °C. It provides high output current capability and super-high-speed operation.

Feature Summary

• Provides bus buffering functionality with three-state output control
• Features 5.5 V tolerant inputs for interfacing with higher voltage logic levels
• Includes power-down protection to prevent excessive current draw during low-power states
• Supports wide operating voltage ranges from 1.65 V to 5.5 V

Applications

• Bus-oriented communications systems
• Clock drivers and buffering
• Memory module data line buffering

Procurement Notes

Verify that the specific part number ending in J(CT corresponds to the -40 °C to 85 °C operating temperature range as specified in the datasheet notes. Confirm the package type is SMV (SOT-753). Ensure compliance with AEC-Q100 requirements if automotive application is intended by contacting the manufacturer directly.

Selection Notes

Select this component when a single-channel buffer with three-state output is required for low-voltage digital applications. It is suitable for designs needing 5.5 V input tolerance and power-down protection. Consider the restricted temperature range of the J(CT suffix variant compared to standard versions which support up to 125 °C.

Part Context

This device belongs to the TC7SZ series of CMOS digital integrated circuits produced by Toshiba Semiconductor and Storage. The series focuses on low-voltage, high-speed logic solutions. The TC7SZ125 specifically functions as a bus buffer, distinct from inverters or gates within the same family.

Replacement Considerations

The datasheet indicates performance matching the TC74LCX series at 3.3 V operation. Verify pinout compatibility and electrical characteristics before substituting with other single-channel bus buffers.
