TC7SET125FU,LJ(CT

Overview

The TC7SET125FU,LJ(CT is a single-channel bus buffer from the TC7SET logic family, manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs controlled by an active-low enable input (G). The device supports TTL-compatible input levels with a maximum low-level input voltage of 0.8 V and a minimum high-level input voltage of 2.0 V. It provides 5.5 V tolerant inputs and delivers output currents of ±8 mA. Propagation delay is typically 3.7 ns at 5.0 V with a 15 pF load. The component is housed in a USV package.

Feature Summary

• AEC-Q100 compliant for automotive reliability requirements
• Wide operating temperature range extending up to 125 °C
• High-speed operation with typical propagation delay of 3.7 ns
• Compatible with TTL output levels and 5.5 V tolerant inputs

Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• Bus buffering applications in digital circuits
• Signal isolation between different logic domains
• Data line drivers in 5 V logic environments

Procurement Notes

Verify that the ordering suffix matches the required temperature grade. Devices ending in (CT) support -40 to 85 °C, while other variants may extend to 125 °C. Confirm RoHS status and packaging type directly with the manufacturer or authorized distributors. Ensure design compliance with absolute maximum ratings to prevent performance deterioration.

Selection Notes

Select this component when a single-channel, non-inverting buffer with three-state control is needed for 5 V logic systems. It is suitable for applications requiring TTL compatibility and high noise immunity. Consider the specific temperature range requirement; verify if the standard or extended temperature variant fits the environmental constraints. Ensure the load capacitance does not exceed specifications to maintain signal integrity.

Part Context

This part belongs to the TC7SET series of CMOS digital integrated circuits. It functions as a bus buffer, providing signal buffering and isolation. The series is designed for general-purpose digital applications, offering low power consumption and high-speed operation. The TC7SET125FU specifically addresses needs for single-channel buffering with tri-state capability in 5 V logic environments.

Replacement Considerations

Check for direct pin-to-pin replacements within the TC7SET family, such as the TC7SET126FU for inverted logic. Verify electrical characteristics like propagation delay and output current against the original design requirements. Ensure the replacement part meets the same AEC-Q100 and RoHS standards if applicable.

FAQ

What is the difference in operating temperature between devices with and without the (CT) suffix?

Devices with the ordering part number ending in (CT) have an operating temperature range of -40 to 85 °C. Other devices in the series may support a wider range up to 125 °C.

Is the TC7SET125FU compatible with TTL logic levels?

Yes, it is compatible with TTL outputs. The low-level input voltage is specified at a maximum of 0.8 V, and the high-level input voltage is a minimum of 2.0 V.

What is the function of the G pin?

The G pin is the control input. When G is Low, the buffer is enabled and the output follows the input. When G is High, the output enters a high-impedance state.
