NOTE:

(1) This device is ESD sensitive. Use of standard ESD handling precautions is required.

(2) Low duty cycle pulse testing with Kelvin connections required.

(3) Defined as the input to output differential at which the output voltage drops 100mV below the value measured

at a differential of 2V.

(4) Guaranteed by design.
