LTC1543IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1543IG#TRPBF is a software-selectable multiprotocol transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and integrates three drivers and three receivers within a 28-lead SSOP package. The device supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via mode select pins M0, M1, and M2. It utilizes an internal charge pump requiring five surface-mounted capacitors to generate the necessary positive and negative voltages for operation.
