The PCA9655EMTTXG from On Semiconductor is a 16-bit General Purpose Input/Output (GPIO) expander that communicates via the I2C/SMBus interface. This device provides 16 I/O pins, which default to inputs upon power-on, allowing for flexible configuration as either inputs or outputs.
Key electrical specifications include an operating voltage range of 1.65V to 5.5V and support for I2C clock frequencies up to 100 kHz, with higher modes available as per the datasheet. The device features an active-low interrupt output that signals changes in input states.
Packaged in a 24-QFN (4x4) with an exposed pad, the PCA9655EMTTXG is designed for surface mounting. It operates across a wide temperature range of -55°C to 125°C. The device also includes features like internal power-on reset and noise filters on SCL/SDA inputs, contributing to robust operation.
This I/O expander is suitable for applications requiring additional digital I/O pins without consuming significant microcontroller resources. Its configurable nature and standard interface make it a versatile component for various embedded systems.
