输入/输出扩展, 8bit, 400 kHz, I2C, SMBus, 1.1 V, 3.6 V, TSSOP

* 400 kHz I²C-bus serial interface * Compliant with I²C-bus Standard-mode 100 kHz * Separate supply rails for core logic and I/O bank provides voltage level shifting * 1.1 V to 3.6 V operation with level shifting feature * Very low standby current: * 8 configurable I/O pins that default to inputs at power-up * Outputs: * Totem pole: 1 mA source and 3 mA sink * Independently programmable 100 kΩ pull-up or pull-down for each I/O pin * Open-drain active LOW interrupt INT output pin allows monitoring of logic level change of pins programmed as inputs * Inputs: * Programmable bus hold provides valid logic level when inputs are not actively driven * Programmable Interrupt Mask Control for input pins that do not require an interrupt when their states change or to prevent spurious interrupts default to mask at power-up * Polarity inversion register allows inversion of the polarity of the I/O pins when read * Active LOW reset RESET input pin resets device to power-up default state * GPIO All Call address allows programming of more than one device at the same time with the same parameters * 2 programmable slave addresses using 1 address pin * -40 °C to +85 °C operation * ESD protection exceeds 7000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101 * Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA * Packages offered: TSSOP16 and HVQFN16
