SN74HC05DRG4

Overview

The SN74HC05DRG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74HC series of high-speed CMOS logic devices. It features six independent inverters with open-drain outputs, designed for operation within a supply voltage range of 2 V to 6 V. The component utilizes a 14-pin SOIC surface-mount package and supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 15 ns at 6 V with a 50 pF load, low static current consumption of 1 µA, and output drive capabilities of ±5.2 mA. It complies with RoHS standards and is moisture sensitive level 1.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• Open-drain output structure suitable for wired-OR applications and level shifting
• High-speed CMOS technology ensuring low power consumption and fast switching speeds
• Wide supply voltage compatibility ranging from 2 V to 6 V

Applications

Procurement Notes

Verify the specific ordering suffix DRG4 to confirm the tape-and-reel packaging format and lead-free composition. Ensure the procurement channel sources genuine Texas Instruments components to avoid counterfeit risks. Confirm RoHS compliance status matches current regulatory requirements for your region. Check for any recent product lifecycle notices regarding availability or obsolescence before finalizing purchase orders.

Selection Notes

Select this component when a hex inverter with open-drain outputs is required for flexible load driving or bus sharing applications. The HC series offers a balance of speed and power efficiency suitable for general digital logic. Consider the 14-pin SOIC package constraints for PCB layout. Verify that the input voltage levels are compatible with the driving source across the entire operating temperature range.

Part Context

This device is part of the standard 74HC family of CMOS logic ICs, widely used in digital electronics for basic logic operations. The SN74HC05 variant specifically provides open-drain outputs, distinguishing it from standard push-pull inverters like the SN74HC04. It serves as a fundamental building block for creating complex logic functions, signal routing, and interface circuits in various electronic designs.

Replacement Considerations

Direct substitutes include SN74HC05DR and SN74HC05DT from Texas Instruments. Cross-manufacturer equivalents such as M74HC05RM13TR from STMicroelectronics may be considered if pinout and electrical specifications match exactly.
