The LTC4300A series hot swappable 2-wire bus buffersallow I/O card insertion into a live backplane withoutcorruption of the data and clock busses. When the connectionis made, the LTC4300A-1/LTC4300A-2 providebidirectional buffering, keeping the backplane and cardcapacitances isolated. Rise-time accelerator circuitry*allows the use of weaker DC pull-up currents while stillmeeting rise-time requirements. During insertion, theSDA and SCL lines are precharged to 1V to minimize busdisturbances.The LTC4300A-1 incorporates a CMOS threshold digitalENABLE input pin, which forces the part into a low currentmode when driven to ground and sets normal operation whendriven to VCC. It also includes an open drain READY outputpin, which indicates that the backplane and card sides areconnected together. The LTC4300A-2 replaces the ENABLEpin with a dedicated supply voltage pin, VCC2, for the cardside, providing level shifting between 3.3V and 5V systems.Both the backplane and card may be powered with supplyvoltages ranging from 2.7V to 5.5V, with no contraints onwhich supply voltage is higher. The LTC4300A-2 also replacesthe READY pin with a digital CMOS input pin, ACC,which enables and disables the rise-time accelerator currents.The LTC4300A is available in a small 8-pin MSOP package.
