Product Summary
The ISO7520CDW is a Low-Power 5 KV(rms) Dual Digital Isolator. The ISO7520CDW provided double galvanic isolation of up to 5KVrms for 1 minute per UL. The ISO7520CDW has two isolated channels with uni-directional channel configurations. Each isolation channel has a logic input and output buffer separated by a silicon oxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The applications of the ISO7520CDW are (1)Medical Applications for IEC 60601-1 5KVrms Rated; (2)Industrial Field-Bus; (3)ProfiBus; (4)ModBus; (5)DeviceNetTM Data Buses; (6)Servo Control Interface; (7)Motor Control; (8)Power Supply; (9)Battery Packs.
Parametrics
ISO7520CDW 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: 150℃.
Features
ISO7520CDW features: (1)Highest Signaling Rate: 1 Mbps; (2)Propagation Delay Less Than 20 ns; (3)Low Power Consumption; (4)Wide Ambient Temperature: –40 to 105℃; (5)Safety and Regulatory Approvals; (6)50 kV/μs Transient Immunity Typical; (7)Operates From 3.3V or 5V Supply and Logic Levels.
