Overview
The SN74HC03DT is a quadruple 2-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and features open-drain outputs capable of sourcing up to 5.2mA in the low state. The device utilizes CMOS technology, ensuring a maximum quiescent current of 2µA. It is housed in a 14-SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates four independent 2-input NAND logic gates within a single package
- Features open-drain output configuration for flexible interfacing
- Operates with low power consumption due to CMOS construction
Applications
- Digital logic signal processing circuits
- Interface adapters requiring open-drain pull-up compatibility
- General-purpose binary logic control systems
Procurement Notes
Verify the specific suffix 'DT' confirms the 14-SOIC package variant. Confirm the active status as distribution channels may list this part as discontinued or obsolete. Ensure the application environment remains within the specified -40°C to +85°C temperature limits. Validate that the open-drain output requirement matches the circuit design needs.
Selection Notes
Select this component when a quad NAND gate with open-drain capability is required. The HC series offers standard CMOS performance suitable for general digital applications. Consider the 14-SOIC package constraints for PCB layout. Verify input voltage levels align with the 2V to 6V supply range requirements.
Part Context
This part belongs to the SN74HC00 series family of high-speed CMOS logic devices. It shares functional similarities with other NAND gates but distinguishes itself through its open-drain output structure. The DT suffix specifically denotes the small-outline integrated circuit package type used in surface-mount assemblies.
Replacement Considerations
Check for SN74HC03 equivalents from other manufacturers offering identical pinouts and electrical characteristics. Verify if alternative packages such as TSSOP are available if space constraints change.
