It allows I\/O card insertion into a live backplane without corruption of the data and clock busses. The LTC4309 provides bidirectional buffering, keeping the backplane and card capacitances isolated. Low offset and high VOL tolerance allows cascading of multiple devices on the clock and data busses. If SDAOUT or SCLOUT are low for 30ms, active-low FAULT will pull low indicating a stuck bus low condition. If DISCEN is tied high, the LTC4309 will automatically break the bus connection and generate upto 16 clock pulses and a stop bit in an attempt to free the bus. A connection will resume if the stuck bus is cleared. If DISCEN is connected to GND, the busses will remain connected with no clock or stop bit generation. Active-low ACC input enables rise-time accelerators for high capacitively loaded busses. It is used in applications such as live board insertion, servers, capacitance buffer\/bus extender, RAID systems, ATCA.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003eBidirectional buffer increases fanout, 60mV buffer offset independent of load\u003c\/li\u003e\n   \u003cli\u003eCompatible with non-compliant VOL I²C devices, ±6kV human body model ESD ruggedness\u003c\/li\u003e\n   \u003cli\u003eIsolates input SDA and SCL lines from output, compatible with I²C�, I²C fast-mode and SMBus\u003c\/li\u003e\n   \u003cli\u003eREADY open drain output, active-low FAULT open drain output\u003c\/li\u003e\n   \u003cli\u003eHigh impedance SDA, SCL pins for VCC = 0, positive supply voltage from 2.3V to 5.5V\u003c\/li\u003e\n   \u003cli\u003eVCC input supply current enabled is 7mA typ at (VCC = VCC2 = 5.5V, VSDAIN = VSCLIN = 0V)\u003c\/li\u003e\n   \u003cli\u003eSDA\/SCL propagation delay high to low is 85ns typ at (CLOAD = 50pF, 2.7K to VCC on SDA, SCL)\u003c\/li\u003e\n   \u003cli\u003eTransient boosted pull-up current is 8mA typ at (positive transition \u0026lt;gt\/\u0026gt; 0.8V\/?S on SDA)\u003c\/li\u003e\n   \u003cli\u003eI²C maximum operating frequency is 600KHz typ at (TA = 25°C.
