The MAX3483ECSA+T from Analog Devices is a 3.3V RS-485/RS-422 transceiver with 250kbps, +/-15kV ESD, and 1uA shutdown in SOIC-8 for low-power communication.
The MAX3483ECSA+T is a 3.3V RS-485/RS-422 transceiver operating at 250kbps data rate in SOIC-8. The driver section converts single-ended TTL/CMOS logic (DI pin) to differential signals on the A and B bus pins. When DE is HIGH, the driver output is enabled and the differential voltage (VA-VB) is approximately 2V for a logic 1 and -2V for a logic 0. The receiver section converts the differential bus signals back to single-ended logic on RO. When RE is LOW, the receiver is enabled. The fail-safe feature ensures RO is HIGH when the bus is open, shorted, or idle (VA equals VB). The ESD protection diodes on A and B pins provide +/-15kV HBM protection. The 250kbps slew-rate-limited driver minimizes EMI and reflections on non-terminated or improperly terminated cables up to 4000 feet. For half-duplex communication, DE and RE are typically tied together and controlled by one GPIO.
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | Output | Receiver output (to UART RX) |
| 2 | RE | Input | Receiver enable (active low) |
| 3 | DE | Input | Driver enable (active high) |
| 4 | DI | Input | Driver input (from UART TX) |
| 5 | GND | Power | Ground |
| 6 | A | I/O | Non-inverting bus pin |
| 7 | B | I/O | Inverting bus pin |
| 8 | VCC | Power | 3.3V supply |
