具有中断、弱上拉和配置寄存器的 8 位 2.3V 至 5.5V I2C/SMBus I/O 扩展器

INT can be connected to the interrupt input of a microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I2C bus. Thus, the PCA9554 can remain a simple slave device.\n\nTh • I2C 至并行端口扩展器\n• 开漏电路低电平有效中断输出\n• 2.3 V 至 5.5V 的工作电源电压范围\n• 耐受 5V 电压的 I/O\n• 400kHz 快速 I2C 总线\n• 3 个硬件地址引脚可在 I2C/SMBus 上支持最多 8 个器件\n• 输入/输出配置寄存器\n• 极性反转寄存器\n• 内部加电复位\n• 所用通道在加电时被配置为输入\n• 在加电时无毛刺脉冲\n• 针对直接驱动 LED 的具有高电流驱动最大能力的锁存输出\n• 锁断性能超过 100mA，符合 JESD 78 II 类规范的要求）\n• ESD 保护性能超过 JESD 22 规范要求 \n• 2;
