Description

The PCA9698DGG is a 16-channel I²C bus I/O port expander designed by NXP Semiconductors. It interfaces with a microcontroller or microprocessor via the I²C protocol, allowing for the expansion of input/output capabilities without requiring additional GPIO pins. The device features two address pins, enabling up to eight PCA9698s to be connected on the same I²C bus, which can increase the total number of I/O ports available.
Each channel can be individually configured as either an input or output, and it supports interrupt generation on input state changes, facilitating efficient communication with the host. The PCA9698DGG operates within a supply voltage range of 1.8V to 5.5V and has a maximum clock frequency of 1 MHz, making it suitable for various applications, including industrial control, automotive, and consumer electronics. Its compact 28-pin TSSOP package allows for easy integration into space-constrained designs.

Features

The PCA9698DGG is an I2C-bus I/O port expander with the following key features:
1. Pin Configuration: 32 GPIO pins, configurable as input or output.
2. I2C Interface: Supports standard I2C-bus communication, operating up to 1 MHz.
3. Multiple Addresses: Up to 8 devices can be connected on the same bus, with selectable I2C addresses.
4. Interrupt Output: Provides an interrupt feature for detecting changes in input states.
5. Open-Drain Output: The GPIO pins can be configured as open-drain or push-pull.
6. Power Management: Supports low-power modes for energy efficiency.
7. Voltage Range: Operates over a wide voltage range (1.8V to 5.5V).
8. Temperature Range: Designed to operate in an extended temperature range (-40°C to +85°C).
These features make the PCA9698DGG suitable for various applications, including embedded systems and peripheral interfacing.
