说明

MAX14770E为半双工、具有±35kV HBM高压ESD保护的收发器,用于PROFIBUS-DP®和RS-485应用。此外,该器件还可用于RS-422/V.11通信。MAX14770E设计满足IEC 61158-2、TIA/EIA-422-B、TIA/EIA-485-A、V.11以及X.27标准。

MAX14770E采用+5V供电,具有真失效保护电路,可确保接收器输入开路或短路时输出逻辑高电平。

MAX14770E接收器输入阻抗为1/4标准单位负载,允许总线上挂接多达128个1/4单位负载的收发器。驱动器具有短路电流限制,并具有热关断电路,可防止过度的功率损耗。

MAX14770E采用8引脚SO封装和8引脚µMAX®封装,工作在扩展级(-40°C至+105°C)温度范围;器件还提供微型TDFN (3mm x 3mm)封装,工作在汽车级(-40°C至+125°C)工作温度范围。
