Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix against official documentation, as variations like SJX or MTC indicate different packages. Confirm availability status, as some variants are discontinued. Ensure the selected part matches the required SOP-20 or TSSOP-20 form factor. Check RoHS compliance details directly from the manufacturer's datasheet before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with three-state control is required. The ACT series offers faster switching speeds compared to standard TTL equivalents. Ensure the design accommodates the 4.5 V to 5.5 V operating voltage range. Verify that the SOP-20 package fits the PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the 74ACT240 family of octal buffers and line drivers. It shares functional similarities with other ACT series devices but is distinguished by its specific pinout and package configuration. The family is designed for high-speed digital applications requiring reliable signal integrity and low power consumption.
