With positive and negative 15KV ESD protection, the chip has a limited slew rate driver to minimize EMI and reduce signal reflections caused by improper terminal matching cables, thereby enabling error-free signal transmission rates up to 500Kbps.
The input impedance of the receiver with a 1/4 unit load supports multi-machine communication, allowing connection to a bus of up to 128 devices.
Using 10Ω current protection resistors, patch design to improve 485 signal integrity.
With terminals and welding lead holes, convenient debugging and final fixed wiring, welding leads can improve signal reliability.
Welding holes with 2.54 pitch holes for easy secondary development. With M3 screw holes that are quite commonly used at present, easy and reliable installation.
