RS-422 RS-423

该系列低功耗、高速收发器适用于RS-485、RS-422和RS-423通信应用。这些产品一般包含一个驱动器和一个半双工配置的接收器。每个驱动器输出和接收器输入都能够经受高达± 15 kV的静电放电,不会产生闩锁效应。这些收发器的工作电压为5 V,空载或满载但驱动器停用的情况下,电源电流消耗非常低。


Small and Powerful RS485 Transceiver,
It’s All About Flexibility and Robustness

Low-power RS-485 transceiver with selectable data rate and compatible with 1.8 V I/Os

A 3.3 V differential line transceiver for RS-485 data transmissions in half-duplex mode, the STR485LV includes an external slew rate select pin able to switch between a fast data rate up to 20 Mbps or a slow data rate up to 250 kbps for longer cables.

Able to interface directly with voltage logic from 1.8 to 3.3 V, this differential driver/receiver is robust over fast transient burst IEC61000-4-4 Class B conditions and the bus pins withstand over ±8kV contact discharge and ±16kV air discharge conditions without latch-up, exceeding IEC 61000-4-2 specifications.

Available in a small (3 x3 mm) DFN10 package with a temperature range from –40 up to +105 °C, the STR485LV is a perfect fit for a wide range of applications including telecom infrastructure, high-speed data links, and low-voltage microcontroller communications.
