The LTC
1694-1 is a dual SMBus active pull-up designed
to enhance data transmission speed and reliability under
all specified SMBus loading conditions. The LTC1694-1 is
also compatible with the Philips I2C Bus.
The LTC1694-1 allows multiple device connections or a
longer, more capacitive interconnect, without compro-
mising slew rates or bus performance, by supplying a high
pull-up current of 2.2mA to slew the SMBus or I2C lines
during positive bus transitions
During negative transitions or steady DC levels, the
LTC1694-1 sources zero current. External resistors, one
on each bus line, trigger the LTC1694-1 during positive
bus transitions and set the pull-down current level. These
resistors determine the slew rate during negative bus
transitions and the logic low DC level.
The LTC1694-1 is available in a 5-pin SOT-23 package.
