SN74ALS03BD

Overview

The SN74ALS03BD 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, a low-level output current capability of 8 mA, and a high-level output current of -8 mA. It functions reliably across an operating temperature range from 0°C to +70°C and is housed in a SOIC-14 package.

Feature Summary

• Open-collector output configuration allows for wired-OR connections and flexible interface driving capabilities.

Applications

• Digital logic signal processing
• Bus line interfacing
• General-purpose switching applications

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard 5V logic systems and check for RoHS compliance status through manufacturer datasheets before procurement.

Selection Notes

Select this component when open-collector NAND functionality is required for bus structures or level shifting. Consider the 50 ns propagation delay and 8 mA drive strength relative to system timing requirements and load conditions.

Part Context

This part is a member of the Texas Instruments SN74ALS family, designed for advanced low-power Schottky applications. It provides quad 2-input NAND gates with open-collector outputs, offering higher speed than standard LS logic while maintaining lower power consumption.

Replacement Considerations

Check for direct equivalents such as the SN74ALS03BDR for reel packaging variants. Verify pinout and electrical characteristics against other ALS-series NAND buffers before substitution.
