批量生产 储存到myST 5V供电电压多通道RS-232驱动器和接收器,温度范围[0℃, 70℃] Order Direct 产品概述 描述 The ST232 is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where ±12V is not available. The ST232...
As the original RS-232 standard was defined in 1962 and before the days of TTLlogic, it is no surprise that the standard does not use 5V and ground logic levels. Instead, a high level for the driver output is defined as between +5V to +15V, and a low level for the driver output i...
RS-232标准接口(又称EIA RS-232)是常用的串行通信接口标准之一,通常以9个引脚(DB-9)或是25个引脚(DB-25)的形态出现,MAX3221EEAE+是常用的RS-232收发器,研发过程中部分用户提出要求,希望推荐其他型号作为备选对比,综合评估。本文推荐RENESAS的RS-232收发器ICL3221EIAZ,封装兼容,参数对齐,满足应用需求。下表是...

2.In the Simulink Real-Time driver block library, double-click the RS232 group block. 3.In the window with blocks for RS-232 legacy drivers, drag an ASCII Encode block to your Simulink model. This block encodes input for the Legacy Serial Port block XMT port. ...
it isn't uncommon for the system to remove power from the UART to also save power. This means that the Vcc pin of the UART will be at ground. If the output of the RS-232 receiver is high, it will forward-bias the protection diode built into the UART. This causes excessive current ...
