MC74ACT244DWG

Overview

The MC74ACT244DWG is an octal buffer and line driver manufactured by onsemi, belonging to the AC logic series. It features eight non-inverting input lines and three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 8 uA, with a maximum operating supply current of 80 uA. Propagation delay is 9 ns at 3.3 V and 7 ns at 5 V. The component supports surface mount installation and functions reliably across an industrial temperature range from -40 C to +85 C.

Feature Summary

• Provides octal buffering and line driving capabilities with non-inverting signal paths.
• Features three-state outputs for effective bus line management and isolation.
• Operates within a wide 2 V to 6 V power supply range for flexible system integration.

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific suffix 'DWG' against the manufacturer's official datasheet to confirm the SOIC-20 package type and tape-and-reel or tube packaging configuration. Ensure compliance with RoHS directives as indicated in the product specifications. Confirm moisture sensitivity levels and recommended storage conditions prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this component when an octal buffer with three-state outputs is required for systems operating between 2 V and 6 V. It is suitable for applications needing non-inverting signal transmission with moderate drive strength. Consider the propagation delay characteristics at the specific operating voltage to ensure timing requirements are met for the target digital circuit design.

Part Context

This part belongs to the MC74AC244 family of octal buffers and line drivers. It shares functional similarities with other devices in the AC logic series but is distinguished by its specific voltage range and package configuration. The MC74ACT244DWG serves as a standard solution for interfacing between different logic families or driving high-capacitance loads in digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative octal buffers such as the MC74AC244 or MC74ACT244 variants from the same manufacturer, ensuring pinout and electrical specifications match the original design requirements.
