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 offset ratings are tested with all supplies biased at

15V differential.

Dynamic Electrical Characteristics

VBIAS (VCC, VBS) = 15V, and CL = 3300 PF and Ta = 25°C unless otherwise specified. The dynamic

electrical characteristics are measured using the test circuit shown in Figure 3 through 6.
