74ACT244SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT244SJX is an octal buffer and line driver belonging to the ACT logic series. It features eight non-inverting inputs and outputs housed in a SOP-20 package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 8 ns at 5 V. Output drive capability includes ±24 mA for both high and low states. Static current is specified at 4 uA, while operating power consumption reaches 40 uA. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix SJX against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status through official documentation before integration. Check for obsolescence notices as this part may be subject to lifecycle changes. Ensure ESD handling protocols are followed during storage and assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 5 V CMOS systems requiring high-speed buffering with significant load driving capabilities. The ACT series offers faster performance than standard LS or HC logic families. Consider the SOP-20 package constraints for PCB layout. Evaluate thermal dissipation requirements if multiple units operate simultaneously under heavy loads.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader 74ACT244 family of octal buffers produced by onsemi. It shares functional similarities with other ACT-series logic components but is distinct from LVX or HCT variants due to its specific voltage and speed characteristics. The SOP-20 packaging distinguishes it from TSSOP or SOIC alternatives within the same logical function category.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with MC74ACT244SCX for potential pin-compatible alternatives. Verify electrical parameters match exactly before substitution. Consult onsemi documentation for any updated revisions that may affect mechanical or electrical specifications.
