The TCA9539QPWRQ1 uses a 24-pin TSSOP package that provides 16-bit universal parallel input and transmission for a two-line, two-way I2C bus (or SMBus protocol) Extend out of (I / O). The device has an operating power supply voltage (VCC) range of 1.65V to 3.6V and supports 100kHz (I2C standard mode) And 400kHz (I2C fast mode) two clock frequencies. When switches, sensors, buttons, LED, fans and other similar devices require additional When I / O, the I / O extender (such as TCA9539-Q1) provides a simple solution.

TCA9539QPWRQ1 includes a break on the INT pin when the state of the input port changes. Hardware optional address pins Up to four A0 and A1.

The TCA9539QPWRQ1 device is located on the same I2C bus. The device can also be reset to the default state by generating the upper power reset. In addition, the TCA9539-Q1 also has a hardware RESET pin that can be used to reset the device to the default state, I2C.

The TCA9539QPWRQ1 has a minimum operating temperature of-40℃ and a maximum operating temperature of 125℃, which is mainly used in; Automotive Infotainment Systems, Advanced Driver Assistance Systems (ADAS), Automotive body electronics, Hybrid Vehicle (HEV), Electric vehicle (EV) and Powertrain, Industrial automation, Factory automation, Building automation, Testing and measurement, Electronic Point-of-sale terminal (EPOS)
