LTC1383CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1383CS#PBF is a low power RS232 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and features two drivers and two receivers. The device supports data rates up to 120kBaud with a 2500pF, 3kΩ load. Supply current is 220µA at no load within the commercial temperature range of 0°C to 70°C. It utilizes four 0.1µF capacitors for its charge pump. Driver outputs provide voltage swings of ±5.0V to ±6.5V. Receiver inputs withstand ±25V without damage and offer ±10kV ESD protection.
