产品介绍
说明
ISO7420x and ISO7421x provide galvanic isolation up to 2500 VRMS for 1 minute per UL and 4242 VPK per VDE. These devices have 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, these devices prevent 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 1). E-grade devices have no integrated noise filter and thus have fast propagation delays. CC-grade devices have integrated 10ns-filter for harsh environments where short noise pulses may be present at the device input pins. 特性
