1 lt1039/lt1039-16 1039fd features descriptio u applicatio s u typical applicatio u rs232 driver/receiver with shutdown the lt 1039 is a triple rs232 driver/receiver that in- cludes shutdown. each receiver will accept up to 30v input and can drive either ttl or cmos logic. the rs232drivers accept ttl logic inputs and output rs232 voltage levels. the outputs are fully protected against overload and can be shorted to ground or up to 30v without damage to the drivers. additionally, when the system isshut down or power is off, the outputs are in a high impedance state allowing data line sharing. bipolar cir- cuitry makes this driver/receiver exceptionally rugged against overloads and immune to latchup. a bias pin allows one receiver to be kept on while the rest of the part is shut down. the lt1039 is also available in the 16-pin version, without shutdown or bias pin functions. for applications requiring operation from a single 5v supply, see the lt1080/lt1081, lt1180a/lt1181a and lt1130a data sheets. for applications requiring 15kv esd, see the lt1039a. , ltc and lt are registered trademarks of linear technology corporation. operates from 5v to 15v supplies fully protected against overload outputs can be driven 30v without damage three-state outputs; outputs open when off bipolar circuitno latchup 30v input range triple driver/receiver no supply current in shutdown 30k w input impedance meets all rs232 specifications 16-pin versionpin compatible with mc145406 available in so package 15kv esd: lt1039a rs232 interface terminals modems driver output swing 30k lt1039 v + 12 3 4 5 6 7 8 9 1817 16 15 14 13 12 11 10 v cc v gnd 12v bias* rs232 in on/off 5vlogic logic logic logic logic logic *bias pin used to keep the receiver on while in shutdown rs232 in rs232 out rs232 out rs232 out rs232 in 12v 1039 ta01 30k 30k output current (ma) 0 output voltage (v) 0.5 v + 8 1039 ta02 0.5 1.0 1.5 v 2 4 6 10 negative positive downloaded from: http:///
