LTC1694IS5#TRPBF

LTC1694IS5#TRPBF is a SMBus/I²C accelerator. It is a dual SMBus active pull-up designed to enhance data transmission speed and reliability under all specified SMBus loading conditions. It also compatible with the Philips I²C™ 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, this device 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. It is used in applications such as notebook and palmtop computers, portable instruments, battery chargers, industrial control application, TV/Video products, ACPI SMBus interface.
