ADI LTC4313IDD-3#PBF

Буфер, ускоритель2-проводная шина2-проводная шина400 кГц1

Overview

The LTC4313 is a hot swappable 2-wire bus buffer that provides bidirectional buffering while maintaining a low offset voltage and high noise margin up to 0.3 • VCC. The high noise margin allows the LTC4313 to be interoperable with devices that drive a high VOL (>0.4V) and allows multiple LTC4313s to be cascaded. The LTC4313IDD-1#TRPBF and LTC4313-2 support level translation between 3.3V and 5V busses. In addition to these voltages, the LTC4313-3 also supports level translation to 1.5V, 1.8V and 2.5V.

If both data and clock are not simultaneously high at least once in 45ms, the input is disconnected from the output. Up to 16 clock pulses are subsequently generated to free the stuck bus. Rise time accelerators (RTAs) provide pull-up currents on SDA and SCL rising edges to meet rise time specifications in heavily loaded systems. The RTAs are configured as slew limited switches in the LTC4313IDD-1#TRPBF and 2.5mA current sources in the LTC4313-2. The LTC4313-3 does not have RTAs.
