多协议收发器

Analog Devices 的 RS-232/RS-485 多协议收发器是市面上独一无二的器件,它们不仅可提供协议切换,而且还能实现半双工 / 全双工操作切换以及终端电阻器的接通 / 关断切换,这两种功能在重新配置网络时均可最大限度减少实际的用户干预。其特点包括 3.3 V 至 5 V 工作电压、高达 ±26 kV ESD、一个逻辑电源引脚、和小型 LFCSP 封装。由于大规模计算应用所需采用的协议往往不止日常应用中常见的 RS 232 和 RS 485 协议,因此我们支持传统型协议。这些协议包括 V.28 (RS-232)、V.35、RS-449、RS-530、RS-530-A、V.36 或 X.21。软件可选协议、电缆端接以及数据终端设备 (DTE) 或数据通信设备 (DCE) 配置均提供了便捷的灵活性。
