具有中断输出、复位和配置寄存器的 16 位 2.3V 至 5.5V I2C/SMBus I/O 扩展器

The system master can reset the PCA9539 in the event of a time-out or other improper operation by asserting a low in the RESET input. The power-on reset puts the registers in their default state and initializes the I2C/SMBus state machine. Asserting RESET causes the same reset/initialization to occu • 1µA 低待机电流消耗（最大值）\n• I2C 至并行端口扩展器\n• 开漏电路低电平有效中断输出\n• 低电平有效复位输入\n• 可耐受 5V 电压的 I/O 端口\n• 兼容大多数微控制器\n• 400kHz 快速 I2C 总线\n• 极性反转寄存器\n• 通过两个硬件地址引脚寻址，以便使用多达 4 个器件\n• 具有高电流驱动能力的锁存输出，用于直接驱动 LED\n• 闩锁性能超过 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• 2000V 人体放电模型 (A114-A)\n• 1000V 带电器件模型 (C101);
