Functional Description:

TDH541S232H is a RS232 transceiver with low power consumption and high electrostatic protection and ESD protection, and it is fullycompliantwithTIA/EIA-232 standards. The main function of the product will be to convert the TTL level to the level of the RS232 protocol to achieve signal isolation.Andthe product comes with a constant voltage isolation power supply, which can achieve 5000VDC electrical isolation, and can also be easilyembeddedinuser equipment, so that the equipment can easily realize the connection function of the RS232 protocol network. TDH541S232H focuses on strengthening the reliability design of TOUT and RIN pins and enhanced ESD design on the basis of traditional IC. ItsTOUT and RIN port ESD tolerance is as high as 15kV (Human Body Model).
