These devices are monolithic low-power Schottky quadruple line receivers designed to satisfy there requirements of the standard interface between data-terminal equipment and data-communication equipment as defined by TIA / EIA-232-F. separate response-control (CONT) terminal is provided for each receiver. A resistor or a resistor and  bias-voltage  source  can  be  connected between this terminal and ground to shift the in put  levels. An external capacitor can be connected between this terminal and ground to provide input noise filtering. The SN55189 and SN55189A are characterized for operation over the full military temperature range  of  – 55°C  to  125°C.  The  MC1489,MC1489A,  SN75189,  and  SN75189A  are characterized for operation from 0°C to 70°C Features :- Input Resistance...3 kΩ to 7 kΩ Input Signal Range...±30 V Operate From Single 5-V Supply Built-In Input Hysteresis (Double Thresholds) Response Control that Provides: Input Threshold Shifting Input Noise Filtering Meet or Exceed the Requirements ofTIA / EIA-232-F and ITU RecommendationV.28 Fully Interchangeable With MotorolaMC1489 and MC1489A Specifications :- Supply Voltage : 4.5V - 5.5V Input voltage : -25 - 25V High-level output current : -0.5mA Low-level output current : 10mA Operating free-air temperature : 70°C Package Includes :- 1 X MC1489 Quadruple Line Receivers IC DIP-14 Package
