LTC4300-2
Overview
The LTC®4300 series hot swappable 2-wire bus buffers allow I/O card insertion into a live backplane without corruption of the data and clock busses. When the connection is made, the LTC4300-1/LTC4300-2 provide bidirectional buffering, keeping the backplane and card capacitances isolated.
- Bidirectional Buffer for SDA and SCL Lines Increases Fanout
- Prevents SDA and SCL Corruption During Live Board Insertion and Removal From Backplane
- Isolates Input SDA and SCL Lines From Output
- Compatible with I2C, I2C Fast Mode and SMBus Standards (Up to 400kHz Operation)
- Low ICC Chip Disable: <1µA (LTC4300-1)
- READY Open-Drain Output (LTC4300-1)
- 1V Precharge on All SDA and SCL Lines
- Supports Clock Stretching, Arbitration and Synchronization
- 5V to 3.3V Level Translation (LTC4300-2)
- High Impedance SDA, SCL Pins for VCC = 0V
