ISL43485 3.3V Half Duplex 30Mbps RS-485/RS-422 Transceiver
The Intersil ISL43485 is a high-speed BiCMOS transceiver powered by 3.3V, designed to comply with both RS-485 and RS-422 standards for balanced communication. This transceiver is specified for power supply tolerances of 10%, ranging from 3V to 3.6V. The receiver...
serial communication introduction
Serial communication using UART or USART of a microcontroller 8051 AVR PIC, software implementation of half-duplex UART and MAX232 interfacing with microcontrollers 8051 AVR PIC.
The described system focuses on implementing serial communication via UART (Universal Asynchronous Receiver-Transmitter) or USART (Universal...
rs-485 circuits
When a network needs to transfer small blocks of information over long distances, RS-485 is often the preferred interface. Network nodes can include PCs, microcontrollers, or any devices capable of asynchronous serial communications. Compared to Ethernet and other network interfaces,...
Carrier Current Transmitter For Data Transmission
In this circuit, data at input C is amplified by IC2 and then fed to modulator IC1. IC1 generates two frequencies, depending on the values of C5, I10, R5, Rn, and R6. The frequency f1 is generated if pin 9...
Carrier-Current Receiver For Data Transmission
This receiver consists of an input network, amplifier IC7, FSK PLL detector IC8, and output amplifier/interface circuits Q2, Q3, IC3A, and IC3B, which include a 1488 Quad RS232 line driver for the carrier-current signal. The tuned amplifier IC7 amplifies this...

Isolated RS-485 and RS-422
Many RS-485 and RS-422 networks require isolation for safety, noise reduction, or ground loop elimination. A conventional circuit is shown in Figure 1. Unfortunately, optocoupler isolation is slow, complicated, and unreliable. Although RTS does not require the same speed as...
