MC1489/D is a four-line EIA−232D receiver produced by ON Semiconductor. It has an input resistance of 3.0 k to 7.0 k�, an input signal range of ±30 V, an input threshold hysteresis characteristic, and can perform logic threshold shifting and input noise filtering
The MC1489 and MC1489A are monolithic quad line receivers designed to interface data terminal equipment with data communications equipment in compliance with the EIA‑232D standard. They feature input resistance, response control, and optional Pb‑free packages.
Key specifications include a 10 V power‑supply rating, 20 mA maximum output load current, and typical propagation delay of 85 ns. Ordering information, package dimensions, and marking diagrams are provided for various SOIC‑14, PDIP‑14, and SOEIAJ‑14 options.
