74HC03D,653

Overview

The Nexperia 74HC03D,653 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 the SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. Static characteristics include a maximum low-level output voltage of 0.4 V at 4.0 mA load and a typical input leakage current of 1 μA at 6.0 V.

Feature Summary

• Quad 2-input NAND logic gates with open-drain output configuration
• Wide supply voltage compatibility ranging from 2.0 V to 6.0 V
• High noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Input clamp diodes enable interfacing to voltages exceeding VCC using current-limiting resistors

Applications

• General digital logic processing requiring NAND functionality
• Interface circuits utilizing current-limiting resistors for voltage translation
• Systems requiring high noise immunity in CMOS environments

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC03D designation corresponds to the SO14 variant. Confirm that the application environment remains within the specified operating temperature limits of -40 °C to +125 °C. Ensure supply voltage constraints do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for CMOS applications. The wide supply voltage range allows flexibility in system design. Verify that the open-drain nature of the outputs aligns with the pull-up requirements of the target circuit architecture. Consider the SO14 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 74HC03 family provides standard NAND logic functions. The 'D' suffix indicates the SO14 surface-mount package, while ',653' denotes the specific tape and reel packaging format used for automated assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 74HC03 specifications in SO14 packages. Ensure pinout compatibility and electrical parameters match the original design requirements before substitution.
