ISL33003数据手册集成电路（IC）的信号缓冲器、中继器、分离器规格书PDF

描述 Description

The ISL33003 two-channel bus buffer provides the buffering necessary to extend the bus capacitance beyond the 400pF maximum specified by the I2C specification. In addition, the ISL33003 features rise time accelerator circuitry to reduce power consumption from passive bus pull-up resistors and improve data-rate performance. The device also includes hot-swap circuitry to prevent corruption of the data and clock lines when I2C devices are plugged into a live backplane, and the ISL33003 adds level translation for mixed supply voltage applications. The ISL33003 operates at supply voltages from +2.3V to +5.5V at a temperature range of -40 °C to +85 °C.
