It provides general-purpose remote I\/O expansion for most microcontroller families via the I2C interface (serial clock (SCL) and serial data (SDA)). The device features an interrupt output (INT) that can be connected to the interrupt logic of the microcontroller, sending an interrupt signal when any input state differs from its corresponding input port register state. The TCA9539RGER is available in a compact 24-pin VQFN (4x4 mm) package, making it ideal for space-constrained applications.\u003c\/p\u003e\u003ch2\u003eDetailed Technical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of I\/Os\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage (VCC)\u003c\/td\u003e\n\u003ctd\u003e1.65 V to 5.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eI2C (up to 400 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e24-VQFN (4x4 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current per I\/O\u003c\/td\u003e\n\u003ctd\u003e±10 mA (source\/sink)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection\u003c\/td\u003e\n\u003ctd\u003eHBM 2000 V, CDM 1000 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003e1 µA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e16-bit bidirectional I\/O ports\u003c\/li\u003e\n\u003cli\u003eI2C bus interface with up to 400 kHz clock frequency\u003c\/li\u003e\n\u003cli\u003eOpen-drain active-low interrupt output\u003c\/li\u003e\n\u003cli\u003eThree hardware address pins allow up to 8 devices on the same bus\u003c\/li\u003e\n\u003cli\u003eLow standby current consumption\u003c\/li\u003e\n\u003cli\u003ePower-on reset with all I\/Os set as inputs\u003c\/li\u003e\n\u003cli\u003eNo glitch on power-up\u003c\/li\u003e\n\u003cli\u003e5-V tolerant I\/Os in power-down mode\u003c\/li\u003e\n\u003cli\u003eLatch-up performance exceeds 100 mA per JESD 78, Class II\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5G base stations: for monitoring and controlling power amplifiers, fans, and status LEDs\u003c\/li\u003e\n\u003cli\u003eAutomotive dashboard: for reading switch inputs and controlling indicator lights\u003c\/li\u003e\n\u003cli\u003eIndustrial PLCs: for expanding digital I\/O for sensor and actuator interfaces\u003c\/li\u003e\n\u003cli\u003eSmart home hubs: for managing GPIO for buttons, LEDs, and relays\u003c\/li\u003e\n\u003cli\u003eMedical devices: for patient monitoring equipment requiring additional I\/O\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"border-bottom:2px solid #eee; padding-bottom:10px; margin-top:40px;\"\u003e\n  Global Supply Chain \u0026amp; Wholesale Solutions\n\u003c\/h2\u003e\n\u003cp\u003eAt Jasin Chip, we provide professional supply chain and wholesale solutions for\n\u003cstrong\u003eTCA9539RGER\u003c\/strong\u003e.
