Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity as this part number is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure the PDIP-20 package matches the target PCB footprint. Check RoHS compliance documentation for specific manufacturing lot requirements before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for 2V to 6V logic systems. The ACQ series offers faster propagation delays compared to standard AC logic while maintaining lower power dissipation than AL variants. Consider the PDIP-20 package constraints for through-hole assembly processes. Evaluate thermal management needs based on the specified operating temperature range of -40°C to +85°C.
