Part Number: DS125BR820

Hi team,

1.For the not used channels ,whether float or connect to gnd?

2.For not use EEPROM Case, how about pull up read_en pin to VDD, and float the all_done pin?

Thanks.

    Hi Frank,

    1). In order to reduce noise propagation, it is better to terminate un-used inputs through 50-Ohm Resistor and AC coupling Capacitors.

    2). You are correct. You can pull READ_EN high - through 1K-ohm resistor and leave ALL_DONE floating.
