74HC03DB,112

Overview

The Nexperia 74HC03DB,112 is a quad 2-input NAND gate featuring open-drain outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and high noise immunity. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component complies with JEDEC standards JESD8C and JESD7A and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Quad 2-input NAND logic function with open-drain output configuration.
• Wide operating supply voltage range supporting 2.0 V to 6.0 V applications.
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.
• Integrated input clamp diodes enabling safe interface to voltages above VCC.

Applications

• General-purpose digital logic circuits requiring NAND functionality.
• Interface circuits utilizing current limiting resistors with inputs.
• Systems demanding high noise immunity and low power consumption.

Procurement Notes

Verify the specific ordering suffix '112' against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution channels may list obsolete or discontinued stock. Ensure compliance with RoHS directives and REACH regulations relevant to your region before procurement.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for wired-AND configurations or level shifting. Verify that the load capacitance and propagation delay characteristics meet the system timing requirements at the intended supply voltage. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 'DB' designation indicates a specific SSOP-14 package variant, which was removed from the standard data sheet in later revisions but remains identifiable via the ordering code. It serves as a fundamental building block for combinational logic designs.

Replacement Considerations

Public confirmed substitute part numbers include 74HC03PW,118.
