ANALOG DEVICES LTC1694-1IS5#TRMPBF

LTC1694-1 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 is also compatible with the Philips I²C bus. It 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 device sources zero current. External resistors, one on each bus line, trigger the device 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. It is widely used in application such as notebook and palmtop computers, portable instruments, battery chargers, industrial control application, TV/video products, ACPI SMBus interface etc.
