9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification, and

TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining

suitability of components for their purposes. Customers should validate and test their design

implementation to confirm system functionality.

9.1 Application Information

The SN74HCS365-Q1 can be used to drive signals over relatively long traces or transmission lines. In order 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 plot 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.

9.2.1 Design Requirements

9.2.1.1 Power Considerations

Ensure the desired supply voltage is within the range specified in the Recommended Operating Conditions. The

supply voltage sets the device's electrical characteristics as described in the Electrical Characteristics.

The positive voltage supply must be capable of sourcing current equal to the total current to be sourced by all

and any transient current required for switching. The logic device can only source as much current as is provided

Absolute Maximum Ratings.
