Product Summary

The ISO7221CD is a dual-channel digital isolator. To facilitate PCB layout, the channel is oriented in the same direction in opposite directions in the ISO7221CD. The ISO7221CD 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 ISO7221CD 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

ISO7221CD 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

ISO7221CD 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.
