Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities when sourcing this component. Confirm the specific package type matches the 56-SSOP form factor required for your design. Ensure the voltage specifications align with your system's power rails. Check for any obsolescence notices from the original manufacturer or current distributors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed, non-inverting bidirectional data transfer. The FCT series offers faster switching speeds compared to standard HC/HCT logic. Consider the 56-pin SSOP package constraints regarding PCB space and thermal dissipation. Ensure the load capacitance requirements of the driven lines are within the device's specified limits for optimal signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context
