NXP USA Inc. PCA9539BS-115 is a 16-bit I/O expander designed for applications requiring expanded digital input/output capability. This device communicates via the I2C and SMBus interfaces, supporting clock frequencies up to 400 kHz. It features Power-On Reset (POR) for reliable initialization and provides push-pull output types with source/sink current capabilities of 10mA and 25mA respectively. The PCA9539BS-115 includes an interrupt output for efficient event reporting. Housed in a compact 24-HVQFN (4x4) surface-mount package, it operates within a voltage supply range of 2.3V to 5.5V and across an industrial temperature range of -40°C to 85°C. This component is commonly utilized in industrial automation, consumer electronics, and automotive systems where flexible I/O management is critical.
