Полупроводники - Микросхемы\Драйверы и Интерфейсы\Специализированные ИнтерфейсыLTC®4311 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. This operates at supply voltages from 1.6V 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, this 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. Typical applications are notebook and palmtop computers, portable instruments, battery chargers, industrial controls, TV/Video products, ACPI SMBus interface.
