SN74HC05NG4

Overview

The SN74HC05NG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74HC logic family. It features six independent inverters with open-drain outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. Packaged in a 14-pin PDIP format, it offers low static power consumption and robust noise immunity typical of CMOS technology.

Feature Summary

• Hex inverter configuration with open-drain output structure
• Wide operating voltage range supporting 2 V to 6 V supplies
• High-speed operation with propagation delay characteristics suitable for general-purpose logic
• Low static power consumption inherent to CMOS technology

Applications

• General-purpose digital signal inversion
• Clock signal buffering and shaping
• Interface circuits requiring open-drain pull-down capability

Procurement Notes

Verify the specific package type and tape/reel or tube packaging options available from authorized distributors. Confirm that the G4 suffix indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the selected variant matches the required pin count and thermal performance for your specific PCB layout constraints.

Selection Notes

Select this component when an open-drain output is required for wired-AND configurations or level shifting between different voltage domains. The HC series provides a balance of speed and power efficiency. Consider the PDIP package only if through-hole mounting is necessary; otherwise, evaluate SOIC or other surface-mount alternatives for automated assembly.

Part Context

This part belongs to the SN74HC05 series of hex inverters with open-drain outputs. It is functionally compatible with other industry-standard 74HC05 devices but may differ in specific electrical parameters and packaging. The G4 suffix typically denotes environmental compliance features such as lead-free terminals.
