SN74ALS03BDR

Overview

The SN74ALS03BDR is a quadruple 2-input positive-NAND buffer with open-collector outputs manufactured by Texas Instruments. It belongs to the ALS logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 50 ns and provides an 8 mA low-level output current. It is housed in a 14-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Integrates four independent 2-input NAND gates with open-collector outputs for flexible wired-logic configurations
• Delivers high-speed performance through a 50 ns propagation delay characteristic typical of the ALS logic family
• Supports robust driving capability with an 8 mA low-level sink current capacity

Applications

• Digital signal processing circuits requiring open-collector NAND logic
• Bus-oriented systems utilizing wired-OR interconnections
• General-purpose logic buffering in industrial control environments

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with standard SOIC-14 footprints during PCB layout. Confirm RoHS compliance status via the latest datasheet before finalizing procurement decisions for regulated assemblies.

Selection Notes

Select this component when open-collector NAND functionality is required for wired-logic applications. The ALS series offers improved speed over standard TTL while maintaining compatible voltage levels. Verify that the 8 mA sink current meets load requirements and that the 50 ns delay fits system timing constraints.

Part Context

This part is a member of the Texas Instruments SN74ALS03A family, designed for high-speed digital applications. It serves as a specialized variant within the broader SN74xx logic portfolio, providing open-collector outputs suitable for interfacing with various logic families and bus structures in electronic designs.

Replacement Considerations

Consult official substitution guides for verified equivalents such as the SN74ALS03AD or SN74ALS03N depending on package requirements.
