Pinout
The ST485ECDR is an RS-485 transceiver integrated circuit designed for bidirectional data communication on multipoint bus transmission lines. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a brief overview of its pin functions:
1. RO (Receiver Output): Outputs the data received from the bus.
2. RE̅ (Receiver Enable): Active low input to enable the receiver. When low, the receiver is enabled; when high, RO is high impedance.
3. DE (Driver Enable): Active high input to enable the driver. When high, the driver is enabled; when low, the driver outputs are high impedance.
4. DI (Driver Input): Accepts the data to be transmitted.
5. GND: Ground reference.
6. A (Non-Inverting Receiver Input/Driver Output): Connects to the bus line for data transmission/reception.
7. B (Inverting Receiver Input/Driver Output): Connects to the bus line for data transmission/reception.
8. VCC: Supply voltage pin.
The ST485ECDR is designed for half-duplex communication and supports data rates up to 5 Mbps, providing robust communication in electrically noisy environments.
