Pinout
The TCA9546APWR is a quad bidirectional I2C switch with four downstream channels. It is designed to increase the flexibility of I2C bus systems by allowing multiple I2C masters and slaves to communicate seamlessly. The device comes in a TSSOP-16 package, which consists of 16 pins.
The key functions of the TCA9546APWR include:
1. I2C Multiplexing: It allows one I2C master to communicate with multiple slaves on different channels.
2. Channel Selection: The channel is selected via the I2C bus using the device’s own address and control register commands.
3. Interrupt Handling: Each channel has an interrupt line that can be used to signal events to the master.
4. Voltage-Level Translation: It supports voltage-level translation between different I2C bus voltages.
The pin configuration includes power supply pins (VCC and GND), I2C bus lines (SDA and SCL), channel selection pins, and interrupt output pins for each channel. This device is commonly used in applications that require multiple I2C devices to be connected to a single I2C master.
