TC74LCX125FTEL

Overview

The TC74LCX125FTEL is a quad bus driver from the 74LCX series, manufactured by Toshiba Semiconductor and Storage. It features four non-inverting buffers with three-state outputs in a 14-TSSOP package. The device operates on a supply voltage range of 1.65V to 3.6V. It provides high drive capability with output currents of 24mA for both high and low states. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent non-inverting buffer circuits
• Features three-state output control via enable input
• Supports low voltage operation down to 1.65V
• Provides high current drive capability of 24mA

Applications

• Memory bus buffering
• Clock distribution networks
• Data line drivers in portable devices

Procurement Notes

Verify the exact suffix FTEL against manufacturer documentation to confirm the tape and reel packaging configuration. Confirm RoHS compliance status as some sources indicate non-compliance while others list it as compliant. Ensure the supplier provides valid traceability documents for this discontinued or limited-stock item.

Selection Notes

Select this component when a quad buffer with three-state functionality is required for low-voltage logic interfaces. The 1.65V to 3.6V supply range makes it suitable for modern portable electronics. Compare drive strength and propagation delay requirements against alternative LCX family members if higher speed is needed.

Part Context

This part belongs to the Toshiba 74LCX series of CMOS logic integrated circuits. The LCX series is designed for low-voltage applications, offering performance comparable to LVC devices but optimized for 1.8V and 3.3V systems. The TC74LCX125 specifically implements the standard quad buffer function with tri-state outputs.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 74LCX125FT from Toshiba Semiconductor and Storage. Other potential equivalents may exist within the same logic family from different manufacturers, but specific cross-brand substitution requires detailed electrical parameter verification.
