74ACT240SCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACT240SCX is an octal buffer and line driver belonging to the 74ACT logic series. It features eight inverting outputs with three-state capability, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8.5 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 4 uA, with a maximum operating temperature of +85 C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's official datasheet to confirm the SOIC-20 package and tape-and-reel orientation. Ensure the order matches the exact 74ACT240SCX designation, as minor variations may exist. Confirm RoHS compliance status directly from the latest product documentation before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal inverting buffers with three-state control. It is suitable for applications needing 5 V operation with moderate speed requirements around 8.5 ns. Compare against non-inverting variants like the 74ACT244 if signal inversion is not required. Ensure the PCB layout supports the SOIC-20 footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT family of CMOS logic integrated circuits manufactured by onsemi. It serves as a standard solution for digital buffering tasks in industrial and consumer electronics. The AC series offers higher speed performance compared to legacy HC or HCT families while maintaining compatibility with standard 5 V logic interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74ACT240MTCX (TSSOP-20 package) and other 74ACT240 variants from different manufacturers. Verify pinout compatibility and package dimensions before swapping. Non-inverting equivalents such as the 74ACT244SCX share similar electrical characteristics but lack signal inversion.
