DIAGNOSTIC LOGIC INDUSTRIAL 8-DIGITAL-INPUT SERIALIZER (SN65HVS882)

Is there a standard way to force logic /logic 0 to the above mentioned product line to ensure correct operation in high rel system. Or is there any alternative way to ensure the above product line is not suffering from stuck at failures?

For our application it is necessary to ensure that the data being received is correct. For that traditionally we used optocoupler for level translation from 24V to 5V/3.3V and used external forcing logic 1/0 to check the integrity of the channel and basically to detect stuck at faults.Is there a provision to provide an integrity check for the digital input channels where we can check for stuck at failures in the device ?

Hi Anindya,

There is no internal integrity check mechanism in serializer parts.
But you should be able to check the integrity by the traditional method of externally forcing the logic.
