The LT1039 is a triple EIA-232 line transceiver designed to meet the requirements of Standard EIA-232-D. All outputs are fully protected against an overload or short to ground. A major advantage of the LT1039 is high-impedance output states when the device is off or powered down. This feature allows several different devices to be connected together on the same bus.
●The bias pin provides a receiver to be kept alive when the LT1039 is shutdown (ON/OFF\ = low).
●The LT1039 is characterized for operation from 0°C to 70°C.
● Meets All EIA-232-D (Revision of RS-232-C) Specifications
● Three Independent Drivers and Receivers Per Package
● EIA-232 Inputs and Outputs Withstand ±30V
● 3-State Outputs
● All Outputs Are Short-Circuit Protected
● Virtually Zero Supply Current When Shutdown
● Output of Several Devices Can Be Paralleled
● Operates From ±5-V to ±15-V Supplies
● Designed to Be Interchangeable With Linear Technology LT1039
