74HCT125TELL-E

Overview

The 74HCT125TELL-E is a non-inverting quad bus buffer manufactured by Renesas Electronics Corporation. It features four independent 1-bit buffers with three-state outputs, designed for high-speed operation within the HCT logic family. The device operates on a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 125°C (TA). It provides LSTTL output logic level compatibility alongside CMOS output compatibility. The component utilizes a 14-pin SOIC package.

Feature Summary

• Non-inverting quad bus buffer architecture with four independent elements
• Three-state output capability allowing high-impedance control
• LSTTL output logic level compatibility for mixed technology systems
• High-speed operation suitable for demanding digital applications

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Transceiver buses for data transmission
• I/O port expansion in embedded systems

Procurement Notes

Verify the specific suffix 'ELL' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match project requirements. Ensure the operating temperature grade aligns with environmental conditions. Cross-reference the package marking with official Renesas documentation to authenticate the component source and prevent counterfeit risks during acquisition.

Selection Notes

Select this component when a non-inverting function with three-state control is required for 5V logic interfaces. It is appropriate for designs needing LSTTL compatibility with CMOS inputs. Consider the thermal performance limits up to 125°C for industrial environments. Evaluate the 14-pin SOIC footprint against available PCB space constraints before finalizing the design integration.

Part Context

This part belongs to the HD74HCT125 series, a standard line of 5V drive bipolar general-purpose logic ICs from Renesas. The series has established market penetration and reliability over decades. The 74HCT125 variant specifically provides non-inverting buffering, distinguishing it from the inverting HD74HCT126 counterpart within the same functional family.

Replacement Considerations

HD74HCT125FP-EL serves as a verified alternative offering identical logical functionality and pin configuration. Both components share the HCT series specifications and three-state output capabilities. Verify package dimensions and marking codes to ensure mechanical compatibility during substitution.
