产品说明

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.

ISO7420FCC has TTL input thresholds and operates from 2.7-V to 5.5-V supplies. All inputs are 5-V tolerant when supplied from a 2.7-V or 3.3-V supply.
