The LTC1694-1 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 compromising 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.
