SN74HC03DG4

Overview

The SN74HC03DG4 is a quad 2-input positive NAND gate manufactured by Texas Instruments. It features open-drain outputs and operates within a supply voltage range of 2V to 6V. The device utilizes CMOS technology and is housed in a 14-SOIC surface-mount package. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Quad 2-input positive NAND logic gates
• Open-drain output configuration
• CMOS technology for low static power consumption

Applications

• General-purpose digital logic circuits
• Signal processing applications requiring open-drain interfaces
• Bus interface systems

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the selected package matches the design footprint requirements. Cross-reference with authorized distributors to validate component authenticity and availability.

Selection Notes

Select this component when open-drain NAND functionality is required for bus sharing or wired-logic configurations. Verify that the load capacitance and pull-up resistor values are compatible with the specified propagation delay and output drive capabilities at the target supply voltage.

Part Context

This part belongs to the SN74HC series, which represents high-speed CMOS logic. It offers performance comparable to the older LS-TTL series but operates at lower voltages. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing standards.
