SN74HC03NG4

Overview

The SN74HC03NG4 is a quad two-input NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features open-drain outputs capable of sourcing or sinking up to 5.2 mA. The device exhibits a propagation delay of 31 ns at 5 V. It functions reliably across an extended temperature range from -40 °C to +85 °C. The component is housed in a 14-pin DIP package.

Feature Summary

• Open-drain output configuration allows flexible interfacing with various logic families and bus structures.

Applications

• General-purpose digital logic circuits
• Bus driver applications requiring wired-AND connections
• Interface between different voltage domains

Procurement Notes

Verify the specific suffix 'NG4' against official Texas Instruments documentation to confirm the exact package type and RoHS compliance status. Ensure the ordering part number matches the required pin configuration and lead finish specifications for your design.

Selection Notes

Select this component when open-drain NAND functionality is required within the HC series performance envelope. Consider the 2 V to 6 V operating range and the 5.2 mA drive capability. Verify that the DIP package format meets the assembly requirements of the target PCB layout.

Part Context

This part belongs to the SN74HC03 family of quadruple two-input NAND gates. The HC series utilizes silicon-gate CMOS technology, offering high noise immunity and low power consumption compared to older logic standards while maintaining compatibility with standard TTL inputs.

Replacement Considerations

Check for SN74HC03N as a potential equivalent without the green manufacturing suffix. Verify cross-manufacturer equivalents such as those from ON Semiconductor or NXP, ensuring they match the open-drain output specification and DIP-14 package.
