description

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.
