Working Principles

LTC1687CS#TRPBF operates based on the RS485/RS422 standard, which uses differential signaling for robust data transmission. The driver section converts logic-level signals into balanced differential voltages, while the receiver section converts the received differential signals back into logic-level signals.

The driver and receiver sections are controlled by the DE (Driver Enable) and RE (Receiver Enable) pins, respectively. When DE is high and RE is low, the driver is enabled, allowing data transmission. Conversely, when DE is low and RE is high, the receiver is enabled, facilitating data reception.
