• Memory address and data bus drivers
• Signal isolation between different circuit sections

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm packaging type, as variants exist in tubes, cut tape, and reels. Ensure the order matches the required moisture sensitivity level and RoHS compliance status. Cross-reference the manufacturer part number with distributor codes to avoid substitution errors during procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 5 V CMOS systems requiring high-speed octal buffering with strong drive strength. The ACT series offers faster switching speeds compared to standard AC logic while maintaining compatibility. Consider the TSSOP-20 footprint constraints and thermal dissipation requirements for dense PCB layouts.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader 74ACT240 family of octal buffers. It shares functional similarities with other onsemi logic devices like the 74ACT244 but differs in pinout configuration and specific electrical characteristics. It serves as a standard interface solution for parallel data transmission in general-purpose electronics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include the 74ACT240MTC tube variant or equivalent parts from other manufacturers adhering to the same 74ACT specification and 20-TSSOP package dimensions.
