SN74HC03PW

Overview

The SN74HC03PW is a quadruple 2-input positive-NAND gate from the Texas Instruments HC logic family. It features open-drain outputs and operates within a supply voltage range of 2 V to 6 V. The device provides low-level output current of 5.2 mA and high-level output current of -5.2 mA, with a propagation delay of 8 ns. It is housed in a TSSOP-14 package and supports surface-mount installation across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Quadruple 2-input NAND logic function
• Open-drain output configuration
• Wide supply voltage operation
• Surface-mount TSSOP-14 packaging

Applications

• Digital signal processing circuits
• Microcontroller interface logic
• General-purpose switching applications

Procurement Notes

Verify the specific part marking against the official datasheet to confirm the SN74HC03PW designation. Ensure the open-drain output requirement matches the system design, as this differs from standard push-pull outputs. Confirm the TSSOP-14 package dimensions align with the PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when a quad NAND gate with open-drain capability is required for wired-OR logic or level shifting. The HC series offers compatibility with standard CMOS logic levels. Verify that the 2 V to 6 V supply range suits the target application power rails and that the 8 ns propagation delay meets the timing constraints of the circuit design.

Part Context

This component belongs to the SN74HC03 series of quadruple 2-input NAND gates. It shares the same logical function as other variants but utilizes the TSSOP-14 package format. The HC series is designed for high-speed CMOS operations, providing performance comparable to standard TTL while maintaining lower power consumption typical of modern CMOS technologies.

Replacement Considerations

Direct substitutes include SN74HC03DR and SN74HC03D, which offer identical logical functions and pinouts in alternative packages.
