74AC244SC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC244SC is an octal buffer and line driver belonging to the AC logic family. It features eight non-inverting channels with three-state outputs, housed in a SOIC-20 package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a maximum low-level output current of 24 mA and a high-level output current of -24 mA. Propagation delay is specified at 9 ns at 3.3 V and 7 ns at 5 V. Static current is typically 4 uA, with a maximum operating temperature of +85 C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel options. Confirm RoHS compliance status through manufacturer documentation. Ensure the ordering part number matches the required lead time and moisture sensitivity level specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for 2 V to 6 V logic systems. Compare propagation delays and output drive strengths against system timing requirements. Consider the SOIC-20 package dimensions for PCB layout constraints relative to alternative packages like TSSOP.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the 74AC244 series of octal buffers. Variants such as MC74AC244DWG share similar electrical characteristics but may differ in packaging. The 74ACT244SC represents a related ACT logic family member with different voltage thresholds. These devices serve as standard interface solutions in digital electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

MC74AC244DWG serves as a verified substitute offering identical logical functionality. Verify pin compatibility and thermal performance before substitution. Check for any differences in manufacturing lot codes or updated revision levels.
