13 / 29 page  IRDM983-025MB, IRDM983-035MB This document is the property of International Rectifier and may not be copied or distributed without expressed consent. 12 Recommended Operating Conditions For proper operation, the device should be used within the recommended conditions. All voltage parameters are absolute voltages referenced to VSS unless otherwise stated in the table. The input/output logic timing diagram is shown in Fig. 1. The VS and VSS offset rating are tested with all supplies biased at a 15 V (VCC) differential / 3.3V (VDD). Power up and down sequences are not dependent on the order of VCC, DCBUS, and VSP for proper operation to start or stop. Symbol Definition Min. Typ Max.
