Descripción general

Description

The SP3483EN-L/TR is a low‑power, half‑duplex RS‑485 transceiver. It combines a differential driver and a receiver in one IC so a microcontroller can talk to an RS‑485 network over a two‑wire bus (A and B). The EN‑L/TR suffix indicates lead‑free RoHS packaging and Tape & Reel delivery.
Key points:
- 2‑wire RS‑485 interface with direction control (DE and RE/EN pins)
- Tri‑state outputs for bus sharing and idle state
- Fail‑safe receiver guarantees a known logic level when the bus is idle or open
- Designed for single‑supply operation (typical 3.3V/5V systems)
- Protects against ESD and short‑circuit conditions on the A/B lines
- Suitable for industrial, building automation, and remote sensor networks
Pinout basics: DI (data in) from MCU, RO (data out) to MCU, A and B to the RS‑485 bus, DE/RE (or EN) for direction control.
For exact electrical specs, performance, and pin configuration, consult the SP3483EN‑L/TR datasheet.

Features

Key features of SP3483EN-L/TR (RS-485/RS-422 transceiver):
- Half-duplex RS-485 transceiver with separate DE (driver enable) and RE (receiver enable)
- 2-wire bus interface with 1/8 unit load
- Single-supply operation (3.3V family; 5V IO tolerant in many variants)
- High-speed data rate up to several Mbps (typical for SP3483 family)
- Fail-safe receiver: RO outputs a logic high when inputs are open, shorted, or idle
- Low quiescent current with optional power-down/shutdown mode
- Wide bus common-mode range with short-circuit protection
- ESD protection on bus pins; suitable for industrial environments
- Industrial temperature range (typical -40 to 85 °C)
- RoHS compliant lead-free package; SP3483EN-L indicates lead-free and -TR indicates Tape & Reel packaging
Note: for exact electrical specs (voltage ranges, max data rate, current consumption), please consult the latest datasheet.

Package

8-pin SOIC (SOP-8) package; TR indicates Tape & Reel. (SP3483EN-L is lead-free; EN-L signifies lead-free).

Pinout

- Pin count: 8 pins (lead-free package; L) with Tape & Reel (TR) variant.
- Function: 8‑pin RS-485/RS-422 transceiver (half‑duplex). Pins include A, B (bus), DI (driver input), RO (receiver output), DE (driver enable), /RE (receiver enable, active low), Vcc, GND. When DE is high, DI drives the bus; when /RE is low, RO reflects bus data.

Manufacturer

- Manufacturer: MaxLinear, Inc. (the SP3483EN-L/TR originated from Sipex/Exar and is now under MaxLinear)
- What kind of company: A fabless semiconductor company that designs and markets analog, RF, and mixed-signal integrated circuits for communications and data networking.

Application

SP3483EN-L/TR is a low-power RS-485/RS-422 transceiver. Applications include industrial automation (PLCs, sensors/actuators), building automation and smart metering, data acquisition/instrumentation, and long-distance, multi-point or point-to-point networks in noisy environments.
