Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SC' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel or tube packaging details. Ensure the ordering part number matches the required moisture sensitivity level and RoHS compliance status for your manufacturing process. Cross-reference the pinout diagram with your PCB layout to prevent orientation errors during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing 5 V CMOS logic interfaces requiring high-speed buffering with significant drive strength. The ACT series offers superior speed compared to standard AC devices while maintaining compatibility with TTL input levels. Consider the SOIC-20 footprint constraints and thermal dissipation requirements relative to the total channel count and ambient operating conditions.
