TCA9802 I2C 电平转换 I2C 总线中继器The TCA9802 is a dual-channel bidirectional buffer intended for I2C bus and SMBus/PMBus systems. It provides bidirectional level shifting (up-translation and down-translation) between low voltages (down to 0.8 V) and higher voltages (1.65 V to 3.6 V). The TCA9802 features an internal current source on the B-side of the device, allowing the removal of external pull-up resistors on the B-side.

通过 I2C 兼容接口提供人机接口器件 (HID) 的低压 8x16 键盘扫描器这个 128 键位扫描器件专门针对操作系统为 Windows 8 的终端设备。 此器件与由已定义的 I2C 技术规范(1.0 版本)(由微软 (Microsoft) 定义)控制的 HID 完全兼容。 此 HID 和报告描述符被固化在器件程序代码中,这样就无需在生产时对它们进行编程。 此器件还有一个预先编程的键盘映射,此映射与大多数标准笔记本/台式机键盘兼容。 然而,也可以提供没有预先设定键盘的器件,这样在生产时可将任何键盘映射写入此器件。
具有中断逻辑和复位功能的 4 通道 I2C 和 SMBus 开关TCA9545A 是一款通过 I2C 总线控制的四路双向转换开关。 串行时钟/串行数据 (SCL/SDA) 上行对分散到四个下行对,或者通道。 根据可编程控制寄存器的内容,可选择任一单独 SCn/SDn 通道或者通道组合。 提供四个中断输入 (INT3-INT0),每个中断输入针对一个下行对。 一个中断 (INT) 输出可作为四个中断输入的与 (AND) 操作。
电平转换 FM+ I2C 总线中继器TCA9617A 是一款专门用于 I2C 总线和 SMBus 系统的 BiCMOS 双路双向缓冲器。 它能够在混合模式应用中提供低压(低至 0.8V)和更高压(2.2V 至 5.5V)之间的双向电压电平转换(上升转换和下降转换)。 电平转换期间,这个器件在不损失系统性能的情况下可扩展 I2C 和相似的总线系统。
