I/O Expanders

The TCA6424ARGJR is a 4-channel, 12-bit I2C GPIO expander from Texas Instruments. It is designed to provide additional general-purpose input/output (GPIO) pins for microcontrollers, allowing for more flexible and expandable system design.

Description:

The TCA6424ARGJR is a 16-pin, low-power I2C GPIO expander that features 4 channels, each with 3 input and 3 output pins. It is available in a 4mm x 4mm QFN package. The device is compatible with I2C standard mode and fast mode, and it supports a wide supply voltage range of 2.5V to 5.5V.

Features:

• 4 channels with 3 input and 3 output pins each
• 12-bit resolution for each channel
• I2C standard mode and fast mode compatible
• Wide supply voltage range of 2.5V to 5.5V
• Active-low reset pin
• Active-low interrupt output pin
• Programmable pull-up resistors for input pins
• Low-power sleep mode
• Small 4mm x 4mm QFN package

Applications:

The TCA6424ARGJR is suitable for a wide range of applications, including:

1. Industrial control systems
2. Home automation systems
3. Robotics
4. IoT devices
5. Wearable electronics
6. Medical equipment
7. Test and measurement equipment
