This device is housed in a TSSOP-20 package and operates across a -40\u00b0C ~ +85\u00b0C. It supports a supply voltage range of 3.0V ~ 5.5V. The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The RS-232 transceiver uses an internal dual charge pump to generate the \u00b15.5V voltage levels required for true RS-232 communication from a single 3.0V to 5.5V supply. The charge pump requires only four small external capacitors. In shutdown mode, the charge pump and transmitters are disabled while receivers remain active, consuming only 1\u00b5A for monitoring external devices.","pin_description":"
