SN74HC05PWRG4

Overview

The SN74HC05PWRG4 is a hex inverter integrated circuit from Texas Instruments, belonging to the 74HC CMOS 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 an operating temperature range from -40°C to +85°C. Packaged in a 14-pin TSSOP (TSSOP-14) surface-mount case, it offers low static power consumption and robust noise immunity typical of HC technology.

Feature Summary

• Hex inverter configuration with open-drain output structure
• CMOS technology ensuring low power dissipation
• Wide supply voltage compatibility from 2 V to 6 V

Applications

• General-purpose digital signal inversion
• Open-drain bus interfacing
• Level shifting between different voltage domains

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and manufacturing origin. Ensure the TSSOP-14 package matches your PCB footprint requirements. Confirm that the open-drain output characteristic aligns with your circuit design, as pull-up resistors are required for proper high-state operation. Check current sourcing capabilities against load specifications.

Selection Notes

Select this component when a hex inverter with open-drain outputs is required for wired-AND configurations or level translation. The HC series provides a balance of speed and power efficiency suitable for general digital logic. Consider the 2 V to 6 V operating range for flexibility in various supply environments. The TSSOP-14 package is appropriate for space-constrained surface-mount designs.

Part Context

This component is part of Texas Instruments' extensive 74HC logic portfolio, which standardizes digital functions across multiple manufacturers. The 'G4' suffix indicates Green/RoHS-compliant manufacturing. As a hex inverter, it serves as a fundamental building block for signal conditioning and logic manipulation in digital systems, distinct from buffered drivers or non-inverting gates.
