SP3483EN-L/TR

SP3483EN-L/TR is a single‑channel RS‑485/RS‑422 transceiver with integrated driver and receiver for half‑duplex serial networks. It provides differential A/B bus pins plus DI (data in) and RO (data out). A DE/RE control (often a combined EN) lets you enable the driver and/or receiver, enabling simple MCU control of transmit/receive. The L suffix denotes a lead‑free package; TR indicates Tape & Reel packaging.
Key use: industrial automation, building control, and any multi‑drop RS‑485 network requiring a compact, low‑power transceiver.
Common features (typical): failsafe receiver so RO remains logic‑high when the bus is idle or open, bus protection and wide bus common‑mode tolerance, low power consumption, and support for data rates up to Mbps. Supply is a single supply (commonly around 3.3 V, with 5 V compatibility per the datasheet).
For exact electrical specs, pinout, and application guidelines, refer to the SP3483EN‑L/TR datasheet.

Equivalent RS-485 half‑duplex, 3.3V, 8-pin transceivers from other vendors include:
- Maxim: MAX3483 (and MAX3483E)
- TI: SN65HVD178x (e.g., SN65HVD1782)
- Analog Devices: ADM3483/ADM3485
These have similar pinouts and 3.3V operation. For exact compatibility, compare DI/RO/DE/RE, A/B, Vcc, and GND pins with SP3483EN-L/TR.

Here are the typical features of SP3483EN-L/TR (RS-485/RS-422 transceiver):
- 3.3V single-supply operation; RoHS lead-free (L) version
- 1-driver/1-receiver, half-duplex RS-485/RS-422 transceiver
- DI data input and RO receiver output
- DE (driver enable) and /RE (receiver enable) control for direction
- High-speed data rate up to a few Mbps on RS-485 bus
- Fail-safe receiver: RO outputs logic-high when inputs are open, shorted, or idle
- Low-power operation with standby/shutdown capability
- Robust protection on A/B lines (ESD/short-circuit protection; wide bus common-mode range)
- Packaging: 8-pin small-outline, Tape & Reel (TR) option
- RoHS-compliant; suitable for industrial/consumer networks
Note: Please refer to the official datasheet for exact electrical specs, timing, and packaging details.

- Pin count: 8 pins (SOIC-8; lead-free variant SP3483EN-L/TR).
- Function: Half‑duplex RS‑485 transceiver. Pins include DI (data input), RO (receiver output), DE (driver enable), RE (receiver enable, active-low), A and B (differential bus), VCC, and GND.

- Manufacturer: MaxLinear, Inc. (SP3483 originates from Sipex; Exar acquired Sipex, and Exar is now part of MaxLinear).
- Company type: A fabless semiconductor company that designs and markets RF, analog, and mixed-signal ICs for broadband, wireless, and data communications.

SP3483EN-L/TR is a high-speed, low-power RS-485/RS-422 transceiver. Typical applications include:
- Industrial automation and PLC networks (Modbus, Profibus)
- Building automation (BACnet MSTP)
- Remote telemetry and data acquisition (SCADA)
- Multi-point sensor networks over long distances
- Any robust RS-485/RS-422 serial links in noisy environments
Concise focus on differential, half-duplex RS-485/RS-422 communication.

SP3483EN-L/TR comes in an 8-pin SOP (SOIC-8) package. The “L” indicates lead-free/RoHS compliant, and “TR” denotes tape-and-reel packaging.
