LTC4301L
Hot Swappable 2-Wire
Bus Buffer with Low Voltage
Level Translation
DESCRIPTIO
The LTC
®
4301L hot swappable, 2-wire bus buffer allows
I/O card insertion into a live backplane without corruption
of the data and clock busses. In addition, the LTC4301L
SDAIN and SCLIN pins are compatible with systems with
pull-up voltages as low as 1V. Control circuitry prevents
the backplane from being connected to the card until a
stop bit or a bus idle is present. When the connection is
made, the LTC4301L provides bidirectional buffering,
keeping the backplane and card capacitances isolated.
When driven low, the CS input pin allows the part to
connect after a stop bit or bus idle occurs. Driving CS high
breaks the connection between SCLIN and SCLOUT and
between SDAIN and SDAOUT. A logic high on READY
indicates that the backplane and card sides are connected
together.
The LTC4301L is offered in 8-pin DFN (3mm
×
3mm) and
MSOP packages.
