PCA9655EDTR2G Description

Short technical summary and product information.

The PCA9655EDTR2G from On Semiconductor is a remote 16-bit General Purpose Input/Output (GPIO) expander that communicates via the I2C-bus or SMBus. This device offers 16 I/O pins that default to inputs upon power-on reset. Each I/O can be configured as either an input or an output through dedicated configuration registers.

 

The PCA9655EDTR2G supports a wide VDD operating range from 1.65V to 5.5V, making it suitable for various applications. It features an active-low interrupt output that signals when an input state changes. The device supports I2C clock frequencies including Standard Mode (100 kHz), Fast Mode (400 kHz), and Fast Mode Plus (1 MHz).

 

Packaged in a 24-TSSOP, the PCA9655EDTR2G is designed for surface mounting. It operates within a temperature range of -55°C to 125°C. The device also includes features like noise filters on SCL/SDA inputs and internal power-on reset for reliable operation. Up to 64 devices can share the same I2C-bus using three address pins (AD0, AD1, AD2) for slave address configuration.
