Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's current datasheet to confirm compliance details and pinout consistency. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements. Confirm that the 4.75V to 5.25V supply voltage range aligns with the system power design specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting bus transceiver with tri-state functionality is required for 5V logic systems. The FCT series offers faster switching speeds compared to standard LS logic. Consider the 20-pin SOIC package for surface-mount assembly constraints. Verify that the 7 ns propagation delay meets the timing requirements of the specific bus interface application.

Buffers, Drivers, Receivers, Transceivers Part Context
