Units VB High side floating absolute voltage -0.3 625 VS High side floating supply offset voltage VB - 25 VB + 0.3 VHO High side floating output voltage VS - 0.3 VB + 0.3 VCC Low side and logic fixed supply voltage -0.3 25 VLO Low side output voltage -0.3 VCC + 0.3 VIN Logic input voltage (HIN & LIN ) VSS - 0.3 VCC + 0.3 dVS/dt Allowable offset supply voltage transient — 50 V/ns PD Package power dissipation @ TA ≤ +25°C (8 lead PDIP) — 1.0 (8 lead SOIC) — 0.625 RthJA Thermal resistance, junction to ambient (8 lead PDIP) — 125 (8 lead SOIC) — 200 TJ Junction temperature — 150 TS Storage temperature -50 150 TL Lead temperature (soldering, 10 seconds) — 300 Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param- eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. Note 1: Logic operational for VS of -5 to +600V. Logic state held for VS of -5V to -VBS. (Please refer to the Design Tip DT97-3 for more details). V °C °C/W W Recommended Operating Conditions The Input/Output logic timing diagram is shown in figure 1. For proper operation the device should be used within the recommended conditions. The VS and VSS offset rating are tested with all supplies biased at 15V differential.
