LTC2845IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC2845IG#PBF is a 5-driver/5-receiver multiprotocol transceiver manufactured by Analog Devices Inc. It operates from a single 3.3V supply and supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via software-selectable mode pins (M0, M1, M2). The component functions as part of a complete DTE or DCE interface port when paired with the LTC2846 or LTC2847. It features internal cable termination for V.10, V.11, and V.28 standards. Electrical characteristics include a typical ICC of 2.7 mA in DCE mode without load, and an operating temperature range of -40°C to 85°C for the 'I' grade. The device is housed in a 36-lead SSOP package.
