DESCRIPTION
Low Voltage I2C/SMBus
Accelerator
The LTC4311 is a dual I2C active pull-up designed to
enhance data transmission speed and reliability for bus
loading conditions well beyond the 400pF I2C specication
limit. The LTC4311 operates at supply voltages from 1.6V
to 5.5V and is also compatible with SMBus.
The LTC4311 allows multiple device connections or a lon-
ger, more capacitive interconnect, without compromising
slew rates or bus performance, by using two slew limited
pull-up currents.
During positive bus transitions, the LTC4311 provides slew
limited pull-up currents to quickly slew the I2C or SMBus
lines to the bus pull-up voltage. During negative transitions
or steady DC levels, the currents are disabled 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. When disabled, the LTC4311
goes into low (<5μA) current shutdown.
The LTC4311 is available in the 2mm
× 2mm × 0.75mm
DFN, and SC70 packages.
