LTC1686/LTC1687 are 52Mbps precision delay RS485 fail-safe transceivers with features including high data rate, low delay skew, high input resistance, and short-circuit protection.
The LTC1686 and LTC1687 are high‑speed, precision‑delay, full‑duplex RS485/RS422 transceivers capable of data rates up to 52 Mbps. They operate from a single 5 V supply, provide fail‑safe operation over a –7 V to 12 V common‑mode range, and include short‑circuit and thermal‑shutdown protection.
Typical applications include high‑speed RS485/RS422 communication, level translation, backplane links, and signal repeaters. The devices feature low propagation‑delay skew, high input resistance, and are pin‑compatible with LTC490/LTC491, making them suitable for industrial, automotive, and telecommunications designs.
