for Increased Drive
Low Profile (1mm) SOT-23 (ThinSOTTM) Package 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 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 …
