CD74AC05EG4

Inverter Gates Overview

The CD74AC05EG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74AC logic family. It features six independent inverters with open-drain outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 1.5V to 5.5V and supports an extended industrial temperature range from -55°C to +125°C. Key electrical characteristics include a maximum static current of 4µA and output drive capabilities of ±24mA. Propagation delay is specified at 8.2ns under standard test conditions.

Inverter Gates Feature Summary

• Hex inverter configuration with open-drain output structure
• Wide operating voltage range supporting low-power applications
• High noise immunity with balanced propagation delays
• ESD protection exceeding 2kV per MIL-STD-883 standards

Inverter Gates Applications

• Open-drain bus interface circuits
• Level shifting between different voltage domains
• Driver circuits for LEDs or relays requiring open-collector behavior

Inverter Gates Procurement Notes

Verify the suffix 'G4' indicates lead-free composition and RoHS compliance during sourcing. Confirm the package type matches the required PCB footprint. Ensure the supplier provides traceability documentation for the manufacturing lot. Check for any specific handling requirements related to moisture sensitivity levels despite MSL rating 1.

Inverter Gates Selection Notes

Select this component when a hex inverter with open-drain outputs is required for wired-OR logic configurations. The AC series offers faster switching speeds compared to standard HC counterparts while maintaining CMOS power efficiency. Consider the 14-SOIC package constraints regarding thermal dissipation and board space availability for high-density designs.

Inverter Gates Part Context

This part belongs to the Texas Instruments CD74AC series of advanced CMOS logic devices. The AC series was designed to provide higher speed performance than earlier 74C or 74HC families while retaining compatibility with standard TTL input levels. The EG4 variant specifically denotes a green, lead-free, halogen-free product with copper lead frame construction.

Inverter Gates FAQ

What is the significance of the open-drain output configuration?

The open-drain outputs allow multiple devices to share a common line (wired-OR) and enable level shifting to voltages higher than the supply voltage, provided an external pull-up resistor is used.

Does the G4 suffix change the logical function?

No, the G4 suffix only indicates environmental compliance attributes such as lead-free pins and RoHS certification; it does not alter the internal circuitry or logical operation.
