Pinout
The LTC4311 is a hot swappable 2-wire bus buffer designed to enhance I2C and SMBus systems. It is housed in a 6-pin SC70 package. The pin functions are as follows:
1. VCC (Pin 1): This is the power supply pin for the device. It typically connects to a 2.7V to 5.5V supply.
2. SDAIN (Pin 2): This is the input for the serial data line. It connects to the SDA line of the I2C or SMBus on the side of the system from which you want to buffer.
3. SCLIN (Pin 3): This is the input for the serial clock line, connected to the SCL line of the bus that requires buffering.
4. SDAOUT (Pin 4): This is the output for the buffered serial data line. It connects to the SDA line on the other side of the buffer.
5. SCLOUT (Pin 5): This is the output for the buffered serial clock line, linked to the SCL line on the opposite side of the buffer.
6. GND (Pin 6): This is the ground pin.
The LTC4311 helps prevent bus stuck conditions, allows for hot swapping, and supports bus capacitance of up to 400pF.
