具有中斷輸出、復位和配置寄存器的 16 位 2.3V 至 5.5V I2C/SMBus I/O 擴展器

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 低待機電流消耗（最大值）\n?
