Product Summary
The ISO7221BD is a dual-channel digital isolator. To facilitate PCB layout, the channel is oriented in the same direction in opposite directions in the ISO7221BD. The ISO7221BD has a logic input and output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4000 VPK. Used in conjunction with isolated power supplies, the ISO7221BD blocks high voltage, isolates grounds, and prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.
Parametrics
ISO7221BD absolute maximum ratings: (1)VCC Supply voltage, VCC1, VCC2: –0.5 V to 6 V; (2)VI Voltage at IN, OUT: –0.5 V to 6 V; (3)IO Output current: ±15 mA; (4)TJ Maximum junction temperature: 170℃.
Features
ISO7221BD features: (1)Low Channel-to-Channel Output Skew; 1 ns max; (2)Low Pulse-Width Distortion (PWD); 1 ns max; (3)Low Jitter Content; 1 ns Typ at 150 Mbps; (4)Typical 25-Year Life at Rated Voltage; (5)UL 1577, IEC 61010-1, IEC 60950-1 and CSA Approved; (6)50 kV/μs Typical Transient Immunity; (7)Operates with 2.8-V (C-Grade), 3.3-V or 5-V Supplies; (8)4 kV ESD Protection; (9)High Electromagnetic Immunity.
