PCA9536DR Description

Short technical summary and product information.

The Texas Instruments PCA9536DR is a 4-bit I/O expander that facilitates general-purpose remote I/O expansion for various microcontroller families. It operates on the I2C and SMBus two-line bidirectional bus, supporting a VCC range of 2.3V to 5.5V and a fast 400kHz bus speed.

 

Key electrical features include 5V tolerant I/O ports, a power-on reset (POR) function, and latched outputs with high-current drive capability suitable for directly driving LEDs. The device also incorporates an input/output configuration register and a polarity inversion register for flexible control.

 

Packaged in an 8-pin SOIC, the PCA9536DR is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. This I/O expander is a valuable component for applications requiring additional digital I/Os without consuming significant microcontroller resources.
