The LTC1694-1CS5#PBF is a dual SMBus/I2C Accelerator designed to enhance data transmission speed and reliability under all specified SMBus loading conditions. It 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, it sources zero current. External resistors, one on each bus line, trigger the accelerator 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.
- Ensures data integrity with multiple devices on the SMBus/I2C
- Improves low state noise margin
