DOWNLOAD. The MC1489 monolithic quad line receivers are designed to interface data terminal equipment with data communications equipment in conformance with the specifications of EIA Standard No. EIA-232D. • Input Resistance - 3.0 k to 7.0 kΩ. • Input Signal Range - ± 30 V. • Input Threshold Hysteresis Built In. The MC1489 interface receivers have internal feedback from the second stage to the input stage providing input hysteresis for noise rejection. The MC1489 input has typical turn-on voltage of 1.25V and turn-off of 1.0 V for a typical hysteresis of 250mV. The MC1489A has typical turn-on of 1.95V and turn-off of 0.8V for typically 1.15V of hysteresis. View All Related Products | Download PDF Datasheet. MC1489, MC1489A. Quad Line EIA-232D. Receivers.
