Pinout
The CBM3485AS8 is an 8-pin (SOP-8 package) RS-485/RS-422 transceiver IC. Key functions include:
- Differential bus communication (RS-485/RS-422 standards).
- Half-duplex operation (driver and receiver share pins).
- Driver enable (DE) and receiver enable (RE) control pins.
- Fail-safe receiver for open/short-circuit conditions.
- 3.3V or 5V supply voltage compatibility.
Pinout (typical):
1. RO – Receiver output
2. RE – Receiver enable (active low)
3. DE – Driver enable
4. DI – Driver input
5. GND – Ground
6. A – Non-inverting bus I/O
7. B – Inverting bus I/O
8. VCC – Power supply
Used in industrial, automotive, and networking applications for robust serial communication.
