TC7SZ34F(T5L,JF,T)

Overview

The TC7SZ34F(T5L,JF,T) is a single-channel non-inverter 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 125 °C, excluding suffixes ending in J(CT). Key electrical specifications include a typical propagation delay of 2.4 ns at 5.0 V with 50 pF load, minimum output current of ±24 mA at 3.0 V, and input capacitance of 4 pF.

Feature Summary

• AEC-Q100 compliant for automotive reliability requirements
• High output drive capability with ±24 mA minimum current
• Super high-speed operation with low propagation delay
• 5.5 V tolerant inputs and power-down protection

Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• Signal buffering in portable devices operating at low voltages
• Interface circuits between different logic families
• High-speed data line drivers

Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature range. Devices with suffixes ending in J(CT) are rated for -40 °C to 85 °C, while other variants support -40 °C to 125 °C. Ensure compatibility with required packaging formats such as SMV (SOT-753). Confirm RoHS compliance status with the manufacturer prior to procurement.

Selection Notes

Select this component when a single-channel non-inverting buffer with high drive strength is required. It is suitable for applications needing 5.5 V tolerance on inputs while operating at lower supply voltages down to 1.65 V. Consider the extended temperature range (-40 °C to 125 °C) for harsh environments, noting that specific suffixes may limit this range. Compare propagation delays against system timing requirements under specific load conditions.

Part Context

This part belongs to the TC7SZ series of CMOS digital integrated circuits from Toshiba. It is designed as a small-scale logic buffer offering high speed and low power consumption. The series is characterized by its ability to operate across a wide voltage range and its compatibility with various logic standards, making it versatile for modern digital designs.

Replacement Considerations

The datasheet notes performance matching with the TC74LCX series when operated at 3.3 V. Verify pinout and electrical characteristics before substituting with other single-buffer ICs.

FAQ
