MAX3485 TTL To RS485 Module

1. ESD protection with positive and negative 15KV.
2. The chip has a limited swing rate driver to reduce EMI and signal reflection caused by inappropriate terminal matching cables, thus making the signal transmission rate of zero defect up to 500 kbps.
3. With 1/4 unit load of the receiver input impedance, support multi-machine communication to is not more than 128 devices on the bus.
4. Industrial chip operating temperature can reach-40 ℃ to +85 ℃.
5. This module can be hot-swap, and there will be no signal plug-in phenomenon hot-swap other 485 chips.
6. The power supply uses a patch-on-aluminum electrolytic capacitor, and uses double capacitors for high and low frequency power supply filtering.
7. Excellent overvoltage protection performance with dual transient suppression diode.
