LTC2862AIS8-1#TRPBF

LTC2862AIS8-1#TRPBF is an Analog Devices (formerly Linear Technology) isolated RS-485/RS-422 transceiver. It provides galvanic isolation between the bus side and the host (logic) side, enabling safe, long-distance differential comms in noisy industrial environments.
Key points
- Isolation: galvanic isolation (typical up to 2.5 kV RMS) between logic and bus
- Interface: differential RS-485/RS-422 transceiver, suitable for half‑duplex operation
- Features: fail‑safe receiver, undervoltage lockout, ESD/surge protection, low power
- Packaging: 8‑pin AIS8 package; Pb‑free; Tape & Reel (TRPBF)
- Applications: industrial automation, process control, building automation, data acquisition
Typical connections
- Bus pins connect to A/B pair
- Logic pins connect to MCU via DI/RO/DE/RE (or equivalent) controls
- Requires isolated supply for the bus side (and a local supply for the logic side)
Note: Exact electrical specs (data rate, voltages, temperature range) vary by variant; consult the datasheet for precise numbers.

- Data rates up to about 20 Mbps per channel.
- 3.3V/5V logic-level compatibility with appropriate thresholds.
- Wide operating temperature: industrial range (-40°C to 125°C).
- Bus protection: robust ESD protection on bus pins and bus-fault tolerance (typical high-voltage/voltage‑clamp protection).
- Fail-safe receiver outputs provide a known state for open/shorted/busy lines.
- Pb-free, 8-pin AIS8 package; Tape & Reel (TRPBF) packaging.
Applications: industrial networks, isolated sensor/actuator interfaces, data link in harsh environments.

- Pin count: 8 pins (AIS8 package)
- Function: Isolated differential transceiver for RS-485/RS-422 (galvanic isolation between sides, differential TX/RX interface).

- Manufacturer: Analog Devices, Inc. (the LTC prefix comes from Linear Technology, which Analog Devices acquired in 2017).
- What kind of company: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs for automotive, industrial, communications, and consumer markets.
