Working Principles

The SN65C3243DWE4 is a transceiver that facilitates serial communication between microcontrollers or other devices. It supports multiple standards such as RS-232, RS-485, and RS-422. The device operates in half-duplex mode, allowing transmission and reception on the same channel.

The transceiver receives data from the microcontroller through the driver input pins (DI) and transmits it to the receiving device via the driver output pins (S, T, U, W). Similarly, it receives data from the receiving device through the receiver input pin (R) and provides the received data to the microcontroller through the receiver output pin (RO).

To ensure reliable communication, the SN65C3243DWE4 incorporates ESD protection, guarding against electrostatic discharge events that could damage the device.
