PCA9536DP,118

A 4-bit general-purpose parallel I/O (GPIO) expander designed for I2C-bus/SMBus applications, featuring 4 configurable I/O bits. It operates across a 2.3 V to 5.5 V supply range with a maximum clock frequency of 400 kHz, supporting CMOS logic levels. Key functionality is provided through a 4-bit Configuration register, Input Port register, Output Port register, and a Polarity Inversion register. The device offers Push-Pull outputs with 10 mA source and 25 mA sink current capabilities, ideal for controlling LEDs, fans, or sensors. Engineered for low power consumption and simple I/O expansion, it incorporates Power-On Reset (POR) and ensures no glitches during power-up. This surface-mount component is housed in an 8-TSSOP package, qualified for operation from -40°C to +85°C. The PCA9536 is an 8-pin CMOS device that provides 4 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications. It features a 4-bit Configuration register, Input Port register, Output Port register, and Polarity Inversion register. It is designed for low power consumption and simple I/O expansion in systems requiring additional control for LEDs, fans, or sensors.
