MC74AC05DR2G

Inverter Gates Overview

The MC74AC05DR2G is a hex inverter integrated circuit manufactured by onsemi, belonging to the 74AC logic series. It features six independent channels housed in a 14-SOIC surface-mount package. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a maximum quiescent current of 4 µA, output drive capabilities of ±24mA, and a maximum propagation delay of 6ns at 5V with a 50pF load. Logic low levels are defined between 0.9V and 1.65V, while logic high levels range from 2.1V to 3.85V.

Inverter Gates Feature Summary

• Hex inverter configuration providing six independent signal inversion paths within a single package.

Inverter Gates Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-14 package and tape-and-reel packaging format. Confirm RoHS compliance status and manufacturing origin through official onsemi documentation or authorized distributor declarations prior to integration into production designs.

Inverter Gates Selection Notes

Select this component when a hex inverter with open-drain outputs is required for 2V to 6V CMOS applications. Consider the 6ns propagation delay and ±24mA drive strength for timing-critical signals. Ensure the design accommodates the open-drain nature, which requires external pull-up resistors for proper high-state logic levels.

Inverter Gates Part Context

This part belongs to the MC74AC family of high-speed CMOS logic devices produced by onsemi. The AC series offers performance improvements over standard HC logic, including faster switching speeds and wider operating voltage ranges. The 74AC05 specifically denotes the hex inverter variant with open-drain outputs, distinguishing it from standard push-pull inverters like the 74AC04.

Inverter Gates FAQ

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

Open-drain outputs can only sink current to ground. They require external pull-up resistors to achieve a high logic state, allowing for wired-OR connections and voltage level translation.

How does the propagation delay vary with supply voltage?

The maximum propagation delay is specified as 6ns at 5V. Performance typically improves (delay decreases) at higher voltages within the 2V-6V range, though exact values depend on load capacitance.
