SN74HC03NSR

Overview

The SN74HC03NSR is a quad 2-input positive NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features open-drain outputs. The device supports surface-mount installation in a 14-SOIC package with a width of 3.90 mm. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Contains four independent 2-input NAND logic gates
• Features open-drain output configuration for wired-AND capabilities
• Compatible with standard CMOS logic families

Applications

• General-purpose digital logic processing
• Bus driver applications requiring open-drain signaling
• Interface circuits between different logic voltage domains

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the component matches the required pinout and electrical characteristics for your design implementation.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required. Verify that the 2 V to 6 V supply range aligns with system power rails. Confirm that the 14-SOIC package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices. It provides standard NAND functionality with enhanced switching speeds compared to legacy LS series components while maintaining low static power consumption typical of CMOS technology.

Replacement Considerations

Check for SN74HC03DR or SN74HC03DRE4 as potential substitutes. Verify pin compatibility and electrical parameters before substitution.
