LTC4300A-3
Overview
The LTC®4300A-3 hot swappable 2-wire bus buffer allows I/O card insertion into a live backplane without corruption of the data and clock busses. When the connection is made, the LTC4300A-3 provides 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
- Logic Threshold ENABLE Input
- Isolates Input SDA and SCL Lines From Output
- Compatible with I2C, I2C Fast Mode and SMBus Standards (Up to 400kHz Operation)
- 1V Precharge on all SDA and SCL Lines
- Supports Clock Stretching, Arbitration and Synchronization
- 5V to 3.3V Level Translation
- High Impedance SDA, SCL Pins for VCC = 0V, VCC2 = 0V
- Small 8-Lead DFN and MSOP Packages
