DM74125N

Overview

The DM74125N is a quad buffer and line driver manufactured by onsemi, housed in a 14-pin DIP package. It features non-inverting logic with three-state outputs for effective bus management. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to 70°C. Electrical characteristics include a high-level output current of 5.2 mA and a low-level output current of 16 mA, ensuring reliable signal transmission in standard digital logic applications.

Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features three-state outputs to facilitate efficient bus-oriented systems
• Designed for through-hole mounting in standard 14-DIP packages

Applications

• Bus-oriented systems requiring controlled signal driving
• Clock distribution networks for timing signals
• Memory address decoding circuits

Procurement Notes

Verify the specific manufacturer source and document revision when sourcing this component, as legacy logic parts may have varying production histories. Confirm that the 14-DIP package dimensions match your PCB footprint requirements precisely. Ensure the supply voltage provided to the circuit remains strictly within the 4.75 V to 5.25 V range to maintain specified electrical performance and reliability standards.

Selection Notes

Select this component when a quad non-inverting buffer with three-state capability is required for digital logic interfacing. It is suitable for designs needing moderate drive strength with low-level output currents up to 16 mA. Consider the through-hole packaging constraint and ensure the operating environment stays within the specified commercial temperature range for optimal functionality.

Part Context

This part belongs to the standard 74-series logic family, specifically designed for general-purpose digital applications. The DM prefix typically indicates a specific manufacturing variant or series designation from onsemi. As a buffered driver, it serves to isolate stages and improve signal integrity in complex digital circuits without altering the logical state of the input signals.

Replacement Considerations

Direct substitutes include SN74125N from Texas Instruments. Verify pin compatibility and electrical specifications before substitution.
