The TCA9555PWR is a 16-bit I/O expander for the two-line bidirectional bus designed for 1.65-V to 5.5-V operation.

The TCA9555PWR consists of two 8-bit Configurations, Input Port, Output Port, and Polarity Inversion. Its I/Os are configured as inputs. To learn more about this I/O expander by Texas Instruments, read on. 

Key Features

16-Bit I/O Expansion

The TCA9555PWR provides 16 additional general-purpose input/output (GPIO) pins, enabling systems with limited I/O capabilities to expand quickly. The 16 bits are divided into two 8-bit ports to give developers flexibility in configuration.

I²C/SMBus Interface

The expander uses a standard I²C or SMBus interface, making it easy to integrate into systems with microcontrollers or processors already using this communication protocol.

Interrupt Functionality

The device supports an interrupt output pin, which alerts the system to changes in input status. This reduces polling overhead and enhances system efficiency, particularly in real-time applications.

Low Power Consumption

Designed for power-sensitive applications, the TCA9555PWR operates with a low standby current of just 1 µA. It supports operating voltages between 1.65V and 5.5V, providing compatibility with various logic levels.

High-Speed Operation

With support for I²C clock speeds of up to 400 kHz, the TCA9555PWR ensures reliable and fast communication, even in complex systems.

Compact Packaging

The TCA9555PWR is packaged in a 24-pin TSSOP package, making it suitable for designs with limited PCB space.

Robust Operating Range

The expander is designed to operate reliably across a temperature range of -40°C to +85°C, making it suitable for harsh industrial environments.

Applications

The TCA9555PWR is a versatile I/O expander that can be applied across a wide range of use cases:

• Industrial control systems

• Consumer electronics

• Embedded systems

• Networking equipment
