RS422/RS485接口电路
凌力尔持提供了众多可供用户选择的工业标准、低功率 CMOS RS485 和 RS422 接口收发器,并具有适合严酷环境的高 ESD 防护、故障保险、高速和高电压版本。我们最新推出的 RS485/RS422 收发器具有一个 -40℃ 至 125℃ 的扩展工作温度范围,从而有助于在苛刻的环境条件 (常常由汽车应用造成) 中确保可靠的数据传输。选择具转换速率限制功能的型号以降低 EMI,而其他型号则包括一个可利用接收逻辑电路来选择的 120Ω 终端。所有器件均专为在采用 3.3V 或 5V 电源的系统中运作而设计,拥有一个 20Mbps 的最大数据速率,并保持一个能够支持多达 256 个节点的高输入阻抗。此外,增强型 ESD 保护可保证在高达 ±15kV HBM 的条件下不会发生损坏或闭锁现象。上述特点再加上一个很宽的操作窗口,使得这些产品成为诸多汽车应用的合适之选,包括电平变换、背板收发和低功率 RS422/RS485 收发。(39)
