ISO1042-Q1: ISO1042BQDWVRQ1

Part Number: ISO1042-Q1

The operating voltage range for primary side is specified from 1.7V to 5.5V (ABS 6V), does the Vin on signal inputs are 5V tolerated when Vcc1 set to 3.3V or 2.5V?

Best Regards,

Robert

  • Hello Robert, 

    As you have stated the recommended VCC1 range is 1.71V - 5.5V with the absolute maximum at 6V. However, this does not mean that the inputs are 5V tolerant at lower VCCx values. The absolute maximum values for Voltage inputs are specified as VIO = VCC1 + 0.5V. Therefore, the maximum input voltage for a 3.3V supply is 3.8V. 

    I hope this helps. 

    Best,
    Andrew
