SN74LS125ADR2

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS125ADR2 is a quadruple bus buffer belonging to the Texas Instruments SN74LS125A series, manufactured by Motorola. It features four non-inverting buffers with three-state outputs and low-power Schottky (LS) logic technology. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial operating temperature range of 0°C to +70°C. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels for signal transmission.
• Features three-state outputs that allow connection to shared data buses without electrical interference.
• Utilizes low-power Schottky (LS) logic technology to reduce power consumption while maintaining high-speed performance.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and register systems
• Clock drivers and buffered outputs
• Bidirectional bus transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation on the component marking, as this part number indicates production by Motorola rather than the typical Texas Instruments origin for the SN74LS125A series. Confirm the specific suffix 'ADR2' corresponds to the required tape-and-reel packaging format and ensure compatibility with the intended application's voltage and thermal specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing digital circuits requiring isolated signal buffering or multi-drop bus architectures. The LS logic family offers a balance of speed and power efficiency suitable for general-purpose TTL applications. Ensure the design accommodates the standard 5V supply requirements and the specific pinout configuration of the SOIC-14 package.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the widely adopted 74LS logic family, which serves as a standard for digital logic functions in industrial and consumer electronics. The SN74LS125 variant specifically addresses the need for controlled signal flow in complex digital systems where multiple devices share common communication lines.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74LS125AD from Texas Instruments and the MC74LS125 from ON Semiconductor. Verify that alternative packages match the physical footprint and that electrical characteristics align with the original design constraints.
