The ADM5180 is an octal differential line receiver suitable for a wide range of digital communication systems with data rates up to 200 kB/s. Input signals conforming to EIA Standards 232-E, 422A and CCITT V.10, V.11, V.28, X.26, and X.27 are accepted and translated into TTL /CMOS output signal levels. The ADM5180 is a superior upgrade for the UC5180C and the NE5180. It is fabricated on an advanced BiCMOS process, allowing high speed bipolar circuitry to be combined with low power CMOS circuitry.
The ADM5180 is an octal differential line receiver designed for high‑speed digital communication up to 200 kB/s. It operates from a single +5 V supply, offers internal hysteresis, low power consumption (≤ 25 mW) and TTL/CMOS compatible outputs. The device includes a failsafe function controlled by FS1 and FS2 that forces a known output level under fault conditions.
The part is offered in 28‑pin DIP and 28‑lead PLCC packages and meets EIA‑232E, 423A, 422A and CCITT V.10, V.11, V.28 standards. Detailed specifications cover power requirements, input thresholds, timing characteristics, absolute maximum ratings and thermal limits, making it suitable for high‑speed modems, printers, computer I‑O ports and logic level translation applications.
