LTC1543CG#PBF

Drivers, Receivers, Transceivers Overview

The LTC1543CG#PBF is a software-selectable multiprotocol transceiver operating from a single 5V supply. It features three drivers and three receivers housed in 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. An internal charge pump generates positive and negative voltages using five external capacitors. Operating temperature range for the C-grade variant is 0°C to 70°C.
