TC74LCX125FT(EL)

Overview

The TC74LCX125FT(EL) is a low-voltage quad bus buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.65 V to 3.6 V, featuring 5-V tolerant inputs and outputs. The device provides high-speed performance with a maximum propagation delay of 6.0 ns at 3.0 V to 3.6 V. It delivers a minimum output current of 24 mA at 3.0 V and includes power-down protection on all inputs and outputs. The component is housed in a 14-pin TSSOP package.

Feature Summary

• Provides four non-inverting buffers with true output polarity
• Features 5-V tolerant inputs and outputs for mixed-voltage interfacing
• Includes power-down protection circuits on all input and output pins
• Offers pin and function compatibility with standard 74 series logic devices

Applications

• General electronics applications such as computers and personal equipment
• Office equipment and measuring instruments
• Industrial robots and home electronics appliances

Procurement Notes

Verify the specific ordering suffix (e.g., FT, EL) against the manufacturer's datasheet to confirm the exact package type and tape-and-reel specifications. Confirm RoHS compliance status directly with Toshiba Semiconductor and Storage or authorized distributors, as environmental declarations may vary by production batch and region.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.65 V and 3.6 V with interface capabilities to 5-V environments. Ensure the application requires a quad bus buffer with 3-state control and verify that the operating temperature range of -40°C to 85°C meets the system requirements.

Part Context

This part belongs to the TC74LCX125 family of low-voltage CMOS digital integrated circuits. The family includes variants with different packaging options such as SOP, JEITA SOP, and VSSOP. All variants share identical electrical characteristics and functionality, differing only in physical package dimensions and weight.

Replacement Considerations

The device is pin and function compatible with other 74 series 125-type buffers, including 74AC, 74VHC, 74HC, 74F, 74ALS, and 74LS families. Verify voltage levels and drive strength when substituting with these alternatives.
