VBIAS (VCC, VBS) = 15 V, CL = 1000 pF and TA = 25 ° C unless otherwise specified.

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

The i nput/ o utput logic timing diagram is shown in Fig. 1. For proper operation the device should be used within the recommended conditions. The VS offset rating is tested with all supplies biased at a 15 V differential.

Note 1: Logic operational for V S of -5 V to +600 V. Logic state held for V S of -5 V to -V BS . (Please refer to the Design Tip DT97-3 for more details).
