LTC4300A-1IMS8#PBF /Код si-311520

LTC4300A-1 is a hot swappable 2-wire bus buffer allow I/O card insertion into a live backplane without corruption of the data and clock busses. When the connection is made, the LTC4300A-1 provide bidirectional buffering, keeping the backplane and card capacitances isolated. Rise-time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise-time requirements. During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. It incorporates a CMOS threshold digital ENABLE input pin, which forces the part into a low current mode when driven to ground and sets normal operation when driven to VCC. It also includes an open drain READY output pin, which indicates that the backplane and card sides are connected together. Applications are hot board insertion, servers, capacitance buffer/bus extender, desktop computer. • Bidirectional buffer for SDA and SCL lines increases fan-out• Prevents SDA and SCL corruption during live board insertion and removal from backplane• Isolates input SDA and SCL lines from output• Compatible with I?C, I?C fast mode and SMBus standards (up to 400kHz operation)• 1V precharge on all SDA and SCL lines• Supports clock stretching, arbitration and synchronization• Positive supply voltage is 2.7 to 5.5V at TA = 25°C• Supply current is 5.1mA typical at VCC = 5.5V, VSDAIN = VSCLIN = 0V, TA = 25°C• 8-lead plastic MSOP package• -40°C to 85°C temperature range
