Linear Technology LTC1694

The LTC1694 is also compatible with the Philips I2CTM Bus. The LTC1694 allows multiple device connections or a longer, more capacitive interconnect, without compromising slew rates or bus performance, by using two bilevel hysteretic current source pull-ups. During positive bus transitions, the LTC1694 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. The LTC1694 is available in a 5-pin SOT-23 package, requiring virtually the same space as two surface mount resistors. , LTC and LT are registered trademarks of Linear Technology Corporation.
