TC74LVX125FTELM

Overview

The TC74LVX125FTELM is a quad bus buffer manufactured by Toshiba Semiconductor and Storage. It operates on a supply voltage range of 2.0 V to 3.6 V with inputs capable of accepting 0 V to 5.5 V levels, enabling direct interfacing between 5 V and 3 V systems. The device features balanced propagation delays and low noise characteristics. It utilizes a 14-TSSOP package and functions within an operating temperature range of -40 °C to 85 °C.

Feature Summary

• Provides four non-inverting buffers with three-state outputs controlled by dedicated enable inputs.
• Accepts input voltages up to 5.5 V regardless of the supply voltage level.
• Includes power-down protection on all inputs to prevent excessive current draw during standby.
• Delivers balanced propagation delays for consistent signal timing across channels.

Applications

• Interfacing 5 V logic systems with 3 V microprocessors or memory devices
• Battery-operated equipment requiring low power consumption
• General-purpose buffering in computer and office automation equipment

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet covers multiple variants including SOP and SOL packages. Confirm the component status directly with the manufacturer, as availability may vary. Ensure compliance with export regulations and intended use restrictions outlined in the official documentation before procurement.

Selection Notes

Select this component when a quad buffer with three-state control is required for mixed-voltage environments. It serves as a functional equivalent to the 74HC125 series while supporting lower supply voltages. Consider its input tolerance for applications where signals exceed the system's main supply rail without risking damage.

Part Context

This part belongs to the TC74LVX125 family of high-speed CMOS digital integrated circuits. It is designed for 3 V systems but maintains compatibility with standard 5 V logic levels through its robust input structure. The device is fabricated using silicon gate CMOS technology to achieve high speed alongside low power dissipation.

Replacement Considerations

Direct substitutes include the TC74LVX125FT and TC74LVX125FN from Toshiba. Other manufacturers offer pin-compatible alternatives such as the 74LVX125MTCX from onsemi, which shares similar electrical specifications and functionality.
