RS232 Transceiver Circuits

There are soo much rs232 transceiver circuit which commond used for communicated between microcontroller and other devices such PC or any devices that use rs232.Here is a collection of rs232 transceiver circuits that popular for today.

2 transistor

The circit below use 2 transistor and some components to provide RS232 transceiver.It usefull for cheap application that dose not long lenght.

MAX232(Full duplex)
The circuit below use MAX232 which is the MAXIM’s devices.This circuit is very stable and use for professional design. This device is inexpensive and it can provides 2 channel for RS232 .

DS275(Half Duplex)
This RS232 transceiver circuit use DS275 which is a small half duplex transceiver chip.
