Description
●ISO7420FCC provides galvanic isolation up to 2500 VRMS for 1 minute per UL and 4242 VPK per VDE. This device has two isolated channels. Each channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. The suffix F indicates low-output option in fail-safe conditions (see Table 2). This device has integrated noise filter for harsh environments where short noise pulses may be present at the device input pins.
