5.4 Electrical Characteristics

Unless otherwise noted, VDD = 18 V, TA = TJ = -40°C to 140°C, IN switching from 0 V to VDD, 1-µF capacitor from VDD to GND, f = 100 kHz. Currents are positive into, negative out of the specified terminal. OUTH and OUTL are tied together. Typical condition specifications are at 25°C.
