Characteristic Unit Max Typ Min Symbol Pins PHASE A OUTPUT Output Low Voltage (IOA = 8.0 mA) 11 VOLA − − 0.4 Vdc Off State Leakage Current (VOHA = 16.5 V) IOHA − − 100 mA POWER SUPPLY Power Supply Current (IOD = 0 mA, IBS = − 300 mA) (L1 = VOHD, L2 = VOLD, L3 = VOHD, L4 = VOLD) (L1 = VOHD, L2 = VOLD, L3 = Hi Z, L4 = Hi Z) (L1 = VOHD, L2 = VOLD, L3 = VOHD, L4 = VOHD) 16 IMW IMZ IMN − − − − − − 70 40 75 mA BIAS/SET CURRENT To Set Phase A 6 IBS − 5.0 − − mA 2. Algebraic convention rather than absolute values is used to designate limit values. 3. Current into a pin is designated as positive. Current out of a pin is designated as negative. 4. DVOD = ⎥VOD1,2 − VOD3,4⎥ where:VOD1,2 = (VOHD1 − VOLD2) or (VOHD2 − VOLD1), and VOD3,4 = (VOHD3 − VOLD4) or (VOHD4 − VOLD3).
