The SN74AHCT245-EP can be used to drive signals over relatively long traces or transmission lines. To reduce ringing caused by impedance mismatches between the driver, transmission line, and receiver, a series damping resistor placed in series with the transmitter’s output can be used. The figure in the Application Curve section shows the received signal with three separate resistor values. Just a small amount of resistance can make a significant impact on signal integrity in this type of application.
