PCA9505DGG,118 Description

Short technical summary and product information.

The NXP Semiconductors PCA9505DGG,118 is a versatile 40-bit parallel input/output (I/O) port expander designed for I2C-bus applications. Organized into five banks of eight I/Os, it offers flexibility for system expansion.

Key electrical specifications include a standard and Fast mode compatible I2C-bus serial interface operating at up to 400 kHz. The device supports a supply voltage range of 2.3 V to 5.5 V, with I/Os that are 5.5 V tolerant. It provides 40 configurable I/O pins that default to inputs at power-up. The outputs are capable of sourcing 10 mA and sinking 15 mA, allowing for direct driving of LEDs. An active LOW output enable (OE) pin can 3-state all outputs, and an open-drain active LOW interrupt (INT) output pin is available for monitoring input pin changes.

This I/O expander operates within an industrial temperature range of -40 °C to +85 °C. It is supplied in a 56-TSSOP package, suitable for surface mount applications.

The PCA9505DGG,118 is designed for I2C-bus applications requiring additional I/O capabilities. Its configurable I/O ports, interrupt functionality, and wide operating voltage make it suitable for various embedded systems.
