MC1489 IC – (SMD Package) – Quadruple Line Receivers IC

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
