SN74HC03D

Overview

The SN74HC03D is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features open-drain outputs. The device supports surface-mount installation in a 14-SOIC package with a width of 3.90mm. Maximum propagation delay is specified at 23ns when operating at 6V with a 50pF load. Static current consumption is limited to 2µA, while output drive capability reaches 5.2mA for both high and low states. Operating temperature spans from -40°C to 85°C.

Feature Summary

• Quad configuration providing four independent 2-input NAND logic functions
• Open-drain output architecture suitable for wired-OR applications
• CMOS technology ensuring low static power consumption

Applications

• General-purpose digital logic processing
• Bus driver implementations requiring open-drain characteristics
• Interface circuits between different logic families

Procurement Notes

Verify the manufacturer part number SN74HC03D against official Texas Instruments documentation to confirm authenticity. Ensure the component matches the 14-SOIC package specification and RoHS compliance status. Cross-reference datasheet parameters such as propagation delay and supply voltage ranges with your specific design requirements before procurement.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for 2V to 6V systems. Consider the 14-SOIC surface-mount package for PCB layout constraints. Verify that the 23ns propagation delay meets timing requirements at the target supply voltage. Ensure compatibility with the -40°C to 85°C operating temperature range.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices produced by Texas Instruments. The 74HC family is designed for general-purpose digital applications, offering performance comparable to standard TTL logic but with lower power consumption. The SN74HC03 variant specifically provides open-drain outputs, distinguishing it from push-pull output variants within the same logic family.
