ISL83386E contains 3.0V to 5.5V power supply RS-232 conforms to the specifications Essence The target application includes PDA, palm computer, and mobile phones to run low, and even lower standby power consumption. The high -efficiency charging pump, and the manual power -off function reduces the current of the backup power supply to 1 Weire. Small packaging, and using small low -value capacitors to ensure that the board space also has savings. The data rate greater than 250kbps is guaranteed to be under the worst load conditions. ISL83386E has a VL tube foot to adjust the output level of the logic pipe (see the instructions of the foot) and the input level of the input and the value of the value compatible with VCC (for example, UART). Single -needle break -off function (SHDN 0) disable all receivers and transmitters output, while turning off the charging pump to minimize the current emissions of the power supply. Table 1 summarizes the characteristics of ISL83386E, and the application description AN9863 summarizes each device including 3V RS-232 series
