LTC1694CS5#TRMPBF

The LTC1694CS5#TRMPBF is a dual SMBus/I?C Accelerator designed to enhance data transmission speed and reliability under all specified SMBus loading conditions. It is also compatible with the Philips I?CTM bus. The LTC1694 allows multiple device connections or a longer, more capacitive interconnect, without compromising slew rates or bus performance, by using two bi-level hysteretic current source pull-ups. During positive bus transitions, the accelerator current sources provide 2.2mA to quickly slew the SMBus line. During negative transitions or steady DC levels, the current sources decrease to 275µA to improve negative slew rate and improve low state noise margins. An auto detect standby mode reduces supply current if both SCL and SDA are high.
