74ACTQ240SCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ACTQ240SCX is an inverting octal buffer and line driver featuring 3-STATE outputs. It utilizes Quiet Series technology to reduce simultaneous switching noise and improve dynamic threshold performance. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. Outputs provide source/sink currents of 24mA with propagation delays as low as 1.5ns at 5.0V.

• Bus oriented transmitters or receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'SCX' corresponds to the SOIC-20 package variant. Confirm that the component status aligns with current production requirements, as datasheets may indicate legacy manufacturing origins. Ensure compatibility with existing board layouts regarding the 20-Lead Small Outline Integrated Circuit dimensions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-density PCB designs require octal buffering with minimized electromagnetic interference. The ACTQ series offers faster propagation delays compared to standard ACT devices. Verify input voltage thresholds match the system logic levels, specifically noting the TTL-compatible inputs typical of the ACT family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACQ/ACTQ Quiet Series family of octal buffers. It is designed to replace standard ACT240 devices where lower noise and higher speed are critical. The SCX suffix denotes the SOIC-20 package configuration, distinguishing it from SOP or QSOP variants within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74ACT240 variants in SOIC-20 packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as propagation delay and output drive strength before substitution.
