PCA9536DGKR Description

Short technical summary and product information.

The PCA9536DGKR from Texas Instruments is a 4-bit I/O expander that facilitates remote I/O expansion for various microcontroller families via the I2C interface. It operates with a supply voltage ranging from 2.3V to 5.5V and supports a fast I2C bus frequency of up to 400kHz.

 

Key features include configuration registers for setting I/O direction, a polarity inversion register, and internal power-on reset. The device boasts 5V tolerant I/O ports, ensuring compatibility with different voltage levels. It also includes a noise filter on SCL/SDA inputs and latched outputs with high-current drive capability, suitable for directly driving LEDs.

 

This I/O expander is available in an 8-VSSOP package, designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. The low standby current consumption of 1 µA is beneficial for power-sensitive applications.

 

The PCA9536DGKR provides essential I/O expansion capabilities with robust features for embedded system designs.
