LTC4304IDD#PBF General Description

During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. When driven high, ENABLE allows the LTC4304 to connect after a stop bit or bus idle occurs. Driving ENABLE low breaks the connection between SDAIN and SDAOUT, SCLIN and SCLOUT. READY is an open drain output that indicates when the backplane and card sides are connected together.

Key Features

Automatic Disconnect of SDA/SCL Lines when Bus is Stuck Low for ≥30ms
Fault Flag for Stuck Bus
Recovers Stuck Busses with Automatic Clocking*
Bidirectional Buffer* for SDA and SCL Lines Increases Fanout
Prevents SDA and SCL Corruption During Live Board Insertion and Removal from Backplane
Allows Bus Pullup Voltages Above and Below V_CC
±15kV Human Body Model ESD Protection
Isolates Input SDA and SCL Lines from Output
Compatible with I²C^™, I²C Fast-Mode and SMBus Standards (Up to 400kHz Operation)
READY Open Drain Output
1V Precharge on All SDA and SCL Lines
High Impedance SDA, SCL Pins for V_CC = 0V
ENABLE Gates Connection from Input to Output
MSOP 10-Pin and DFN (3mm × 3mm) Packages

Application

Hot Board Insertion
Servers
Capacitance Buffer/Bus Extender
RAID Systems
