Datasheet Summary
Powered by GS/AI

The PCA6107DWR is an 8-bit I/O expander designed for I¬=C and SMBus interfaces, suitable for low-power applications. It operates within a supply voltage range of 2.3 V to 5.5 V and features a low standby current consumption of 1 OºA maximum. The device supports up to eight I¬=C addresses through three hardware address pins, allowing multiple devices to be connected on the same bus. The PCA6107 includes an open-drain active-low interrupt output that signals changes in input states, facilitating efficient communication with a microcontroller without continuous I¬=C bus activity. It also features a reset input, configuration registers, and polarity inversion capabilities for input ports. The output ports are capable of high-current drive, making them suitable for directly driving LEDs. The device is packaged in an 18-pin SOIC format and is rated for operation in temperatures ranging from -40¬8C to 85¬8C. Engineers should consider the PCA6107DWR for projects requiring a compact, low-power I/O expansion solution with interrupt capabilities and flexibility in configuration.
