The MC3486 offers four independent differential-input line receivers that have TTL-compatible outputs. The outputs utilize 3-state circuitry to provide a high-impedance state at any output when the appropriate output enable is at a low logic level. The MC3486 is designed for optimum performance when used with the MC3487 quadruple differential line driver. It is supplied in a 16-pin package and operates from a single 5-V supply. The MC3486 is characterized for operation from 0°C to 70°C. FUNCTION TABLE (each receiver) ENABLE OUTPUT Y VID ≤ 0.2 V – 0.2 V < VID < 0.2 V H H H ? VID ≤ – 0.2 V Irrelevant H L L Z Open H ?
