SN74AS244ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS244ADW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the AS logic series. It features eight non-inverting inputs organized into two independent four-bit sections, each equipped with a separate three-state output enable control. The device utilizes bipolar technology and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with a green plastic construction. Key electrical characteristics include a maximum low-level output current of 64 mA and a load capacitance rating of 50 pF.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-20 package variant when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the operating temperature range aligns with system requirements before integration. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed buffering with bipolar drive strength. Compare against LVC or ABT series alternatives if lower power consumption or different voltage compatibility is required. Verify that the 5V-only supply constraint fits the target system architecture. Consider thermal dissipation capabilities within the SOIC-20 package for dense layouts.
