CD74HC03M

Inverter Gates Overview

The CD74HC03M is a quad 2-input NAND gate manufactured by Harris Corporation, belonging to the HC/UH CMOS logic series. It features open-drain outputs and operates within a supply voltage range of 2V to 6V. The device is housed in a 14-SOIC surface-mount package with 14 terminals. Key electrical parameters include a maximum output current (Iol) of 0.004 A and a load capacitance (CL) of 50 pF. Propagation delay is specified at 39 ns at nominal supply, with a maximum of 165 ns. It supports an operating temperature range from -40°C to 85°C.

Inverter Gates Feature Summary

• Quad configuration providing four independent 2-input NAND gates in a single package
• Open-drain output structure suitable for wired-AND applications and level shifting
• CMOS technology ensuring low power consumption and high noise immunity

Inverter Gates Applications

• Digital logic circuits requiring NAND functionality
• Wired-OR/Wired-AND bus configurations utilizing open-drain outputs
• Interface circuits for voltage level translation between different logic families

Inverter Gates Procurement Notes

Verify component authenticity as Harris Corporation assets were acquired by Renesas Electronics. Confirm manufacturing date codes and lot traceability against original specifications. Ensure the SOIC package matches the required footprint and pinout. Check for RoHS compliance status if required by modern assembly standards, noting that older Harris production may not meet current environmental directives.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for HC-speed performance. The 14-SOIC package is appropriate for surface-mount assembly processes. Consider the 2V to 6V supply range compatibility with the target system voltage. Verify that the open-drain nature meets the pull-up requirements of the specific application circuit design.

Inverter Gates Part Context

The CD74HC03M is part of the standard 74HC series of high-speed CMOS logic devices originally produced by Harris Corporation. This series was widely adopted for general-purpose digital logic applications due to its speed and power efficiency. Harris Corporation's logic division later became part of Renesas Electronics following corporate acquisitions, affecting long-term sourcing channels for these legacy components.

Inverter Gates Replacement Considerations

Equivalent parts include SN74HC03N or SN74HC03D from Texas Instruments, which offer identical logical function and pinout. Other compatible alternatives from manufacturers like ON Semiconductor or STMicroelectronics should be verified for matching supply voltage ranges and package dimensions.
