- Separate VIO logic supply (vs MAX3485E)
- IEC ±12 kV ESD protection (vs SN65HVD3082E)
Design Notes
Place the ADM3066EBRMZ close to the bus connector to minimize trace length and reduce EMI. Use 120 Ω termination resistors at both ends of the RS-485 bus to prevent reflections. Keep the A and B traces parallel and close together to maintain differential impedance.
Decouple the VCC and VIO pins with 0.1 µF ceramic capacitors placed as close as possible to the pins. For noisy environments, add a 10 µF bulk capacitor. Ensure the VIO supply is within the specified range (1.62 V to 5.5 V) to avoid logic interface damage.
Do not exceed the absolute maximum ratings for VCC and VIO. Ensure the bus is properly terminated to avoid signal integrity issues. The RE and DE pins should be controlled to prevent bus contention. For half-duplex operation, ensure only one driver is active at a time.
