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 microcontroller's interrupt input, alerting the system of input changes without polling. Three hardware address pins (A0, A1, A2) allow up to eight devices on the same bus, expanding I\/O capability up to 128 bits. The TCA9539AQPWRQ1 is qualified to AEC-Q100 for automotive applications and operates over a wide temperature range of -40°C to +125°C.\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\/O Pins\u003c\/td\u003e\n\u003ctd\u003e16\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\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e2.3 V to 5.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +125°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current per Pin\u003c\/td\u003e\n\u003ctd\u003e±10 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e24-TSSOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuiescent Current\u003c\/td\u003e\n\u003ctd\u003e1.5 μA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection\u003c\/td\u003e\n\u003ctd\u003e±8 kV HBM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAEC-Q100 Qualified\u003c\/td\u003e\n\u003ctd\u003eYes\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 with I2C interface\u003c\/li\u003e\n\u003cli\u003eThree hardware address pins allow up to 8 devices on bus\u003c\/li\u003e\n\u003cli\u003eOpen-drain active-low interrupt output\u003c\/li\u003e\n\u003cli\u003eInput\/output configuration register\u003c\/li\u003e\n\u003cli\u003ePolarity inversion register\u003c\/li\u003e\n\u003cli\u003eInternal power-on reset\u003c\/li\u003e\n\u003cli\u003eNo glitch on power-up\u003c\/li\u003e\n\u003cli\u003eLow standby current consumption\u003c\/li\u003e\n\u003cli\u003eSchmitt-trigger action allows slow input transition\u003c\/li\u003e\n\u003cli\u003e5 V tolerant I\/Os\u003c\/li\u003e\n\u003cli\u003eAutomotive grade: AEC-Q100\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAutomotive body control modules (e.g., door modules, seat control)\u003c\/li\u003e\n\u003cli\u003eInfotainment systems (e.g., dashboard displays, steering wheel controls)\u003c\/li\u003e\n\u003cli\u003eAdvanced driver-assistance systems (ADAS) sensor interfaces\u003c\/li\u003e\n\u003cli\u003e5G base station control and monitoring\u003c\/li\u003e\n\u003cli\u003eIndustrial automation (e.g., PLC I\/O expansion)\u003c\/li\u003e\n\u003cli\u003eServer and telecom equipment (e.g., fan control, status LEDs)\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\u003eTCA9539AQPWRQ1\u003c\/strong\u003e.
