Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer source as this component may be discontinued or subject to lifecycle changes. Confirm that the 24-SOIC package matches the target PCB footprint and soldering profile requirements. Ensure the operating voltage aligns strictly with the 4.5V to 5.5V specification to prevent functional failure. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust octal data buffering with defined drive strength. The ACT series offers faster switching speeds compared to standard LS logic while maintaining CMOS low power consumption. Verify that the load capacitance requirements do not exceed the datasheet limits to maintain signal integrity. Consider the thermal dissipation capabilities of the SOIC package if operating near maximum temperature extremes.
