74HC03DB,118

Overview

The Nexperia 74HC03DB,118 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 a 14-lead SO plastic small outline package (SOT108-1). Static characteristics include a low-level output voltage of 0.26 V max at 5.2 mA and 6.0 V supply. Dynamic performance specifies a propagation delay of 20 ns max at 6.0 V with 50 pF load capacitance.

Feature Summary

• Quad configuration providing four independent 2-input NAND logic functions
• Open-drain output architecture enabling wired-AND connections and voltage level shifting
• Input clamp diodes allowing interface to voltages exceeding the supply rail using current limiting resistors

Applications

• General-purpose digital logic processing in CMOS systems
• Voltage level translation between different logic families
• Wired-AND bus configurations requiring open-drain topology

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead-free soldering compatibility requirements for your assembly process. Ensure the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for interfacing or bus applications. Verify that the input voltage levels match the CMOS standards defined for the HC series. Ensure the design accommodates the open-drain nature by including appropriate pull-up resistors on the output lines to achieve high logic states.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard 74HC03 equivalents but offers specific packaging and reliability characteristics defined by Nexperia. The DB suffix indicates the SSOP/SOIC package variant, distinct from other package options like TSSOP available in the same logical family.

Replacement Considerations

Check for direct pin-compatible alternatives such as the 74HCT03D variants if TTL input levels are needed instead of CMOS. Verify that any substitute maintains the open-drain output characteristic and the 14-lead SO package dimensions.
