Product Overview

The LTC4311ISC6#PBF is a low voltage I²C/SMBus Accelerator designed to enhance data transmission speed and reliability for bus loading conditions well beyond the 400pF I²C specification limit. It operates at supply voltages from 1.6 to 5.5V and is also compatible with SMBus. It allows multiple device connections or a longer, more capacitive interconnect, without compromising slew rates or bus performance, by using two slew limited pull-up currents. During positive bus transitions, the accelerator 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.
  • Improves low state noise margin
  • Up to 400kHz Operation
  • Auto detect low power standby mode
  • Does not load bus when disabled or powered down
  • Strong slew limited pull-up current
  • <5µA Low supply current shutdown
