Overview
The SN74HC03DRG4 is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the HC logic series and features open-drain outputs, distinguishing it from standard push-pull variants. The device operates within a supply voltage range of 2 V to 6 V and supports propagation delays as low as 8 ns. It is housed in a 14-pin SOIC package with a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Contains four independent 2-input NAND gates within a single package.
- Features open-drain output configuration for wired-AND capabilities.
- Operates across a broad supply voltage range from 2 V to 6 V.
- Designed for surface-mount installation in compact electronic assemblies.
Applications
- Digital logic signal processing
- Wired-OR logic implementation
- Interface circuits requiring open-drain outputs
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the package type is SOIC-14 and ensure the open-drain output characteristic matches the design requirements, as this differs from standard push-pull logic gates. Cross-reference the full part number against official Texas Instruments databases to confirm current production status and availability.
Selection Notes
Select this component when an open-drain NAND function is required rather than standard push-pull outputs. The HC series offers compatibility with standard CMOS logic levels while providing flexibility for interfacing with different voltage domains due to the wide supply range. Ensure the application can accommodate the pull-up resistor requirement inherent to open-drain configurations.
Part Context
This part is a variant of the SN74HC03 series, specifically the SN74HC03DRG4. The 'D' denotes the SOIC package, while 'R' indicates tape-and-reel packaging. The 'G4' suffix typically signifies environmental enhancements such as lead-free composition. It is distinct from the SN74HC00, which uses push-pull outputs instead of open-drain.
Replacement Considerations
Direct substitutes include other SN74HC03 variants with compatible packages, such as SN74HC03N (PDIP) or SN74HC03PW (TSSOP), provided the pinout and electrical characteristics match. Verify that alternative sources maintain the open-drain output specification.
