PCA9544A | 4-channel IC multiplexer with interrupt logic DESCRIPTION The PCA9544A is a 1-of-4 bi-directional translating multiplexer, controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four SCx/SDx downstream pairs, or channels. Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control registe | PHILIPS 飞利浦 |   | |

PCA9544A | 具有中断和电压转换的 4 通道 2.3V 至 5.5V I2C/SMBus 多路复用器 PCA9544A 是一款由 I2C 总线控制的 4 通道双向转换多路复用器。SCL/SDA 上行对扩展到四个下行对，或者通道。根据可编程控制寄存器的内容，每次可选择任一 SCL/SDA 对。提供四个中断输入 (INT3-INT0)，每个中断输入针对一个下行对。一个中断输出 (INT) 是四个中断输入的与运算结果。\n\n 上电复位功能使寄存器处于缺省状态，并初始化 I2C 状态机，无需选择任何通道。\n\n 由于开关上有导通栅极，因此 VCC 引脚可用于限制将由 PCA9544A 传递的最大电压。这允许在每个对上使用不同的总线电压，以便 1.8V，2.5V 或 3.3V 部件可以在没有任何额外 • 4 选 1 双向转换开关\n• 与 I2C 总线和 SMBus 兼容\n• 四个低电平有效中断输入\n• 低电平有效中断输出\n• 三个地址引脚，I2C 总线上最多支持八个器件\n• 通过 I2C 总线选择通道\n• 加电时所有开关通道取消选定\n• 低 RON 开关\n• 支持在 1.8V、2.5V、3.3V 和 5V 总线间进行电压电平转换\n• 加电时无干扰\n• 支持热插入\n• 低待机电流\n• 工作电源电压范围为 2.3V 至 5.5V\n• 5.5V 耐压输入\n• 0 至 400kHz 时钟频率\n• 闩锁性能超过 100mA，符合 JESD 78 规范\n• ESD 保护; | TI 德州仪器 | | |
