Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description

The SL485N is designed for RS-485/RS-422 communication. It is a full-duplex communication transceiver that includes one driver and one receiver, featuring driver enable (DE) and receiver enable (RE) pins. When disabled, the driver and receiver outputs are in a high-impedance state. It has a fail-safe circuit that ensures the receiver output is correct even if the receiver input is open-circuited or short-circuited. It also has a +15kV ESD (Electrostatic Discharge) protection feature. Additionally, its receiver has a 1/8 unit load input impedance, allowing up to 256 transceivers to be connected on the bus. Compared to traditional 485 chips, the SL485N has an adaptive feature that allows communication regardless of the L1 and L2 connection (no need to distinguish L1 and L2), with a communication rate that must be greater than 25Hz.
