DESCRIPTION

Now Available in Lead Free Packaging

The SP503 is a highly integrated serial transceiver that allows software control of its interface

modes. It offers hardware interface modes for RS-232 (V.28), RS-422A (V.11), RS-449, RS-485,

V.35, and EIA-530. The SP503 is fabricated using low–power BiCMOS process technology, and

incorporates a Sipex patented (5,306,954) charge pump allowing +5V only operation.
