MC74AC244DWR2G

Buffers, Drivers, Receivers, Transceivers Overview

The MC74AC244DWR2G is an octal buffer and line driver from the onsemi AC logic series. It features eight non-inverting inputs and three-state outputs housed in a 20-pin SOIC-Wide package. The device operates within a supply voltage range of 2 V to 6 V, with a maximum low-level output current of 24 mA and a high-level output current of -24 mA. Static current is specified at 8 uA, while operating power consumption reaches 80 uA. Propagation delay is 9 ns at 3.3 V and 7 ns at 5 V. It functions reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix DWR2G against the manufacturer's official datasheet to confirm the SOIC-20 wide package and tape-and-reel packaging configuration. Ensure the AC logic family designation matches the design requirements for voltage levels and speed. Confirm RoHS compliance status through the component's material declaration documents prior to final procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for systems operating between 2 V and 6 V. The AC series offers a balance of speed and power consumption suitable for general-purpose digital interfaces. Consider the 20-pin SOIC-Wide package for PCB layout constraints and thermal dissipation needs relative to other available packages in the same logic family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the MC74AC244 family of octal buffers. It serves as a digital interface component designed to drive loads and isolate signals on data buses. The AC series represents a specific performance tier within onsemi's broader logic portfolio, distinct from HC or HCT variants regarding voltage tolerance and switching characteristics.
