LTC1383IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC1383IN#PBF is a 5V low power RS232 transceiver manufactured by Analog Devices Inc. It features two drivers and two receivers, supporting full duplex communication at data rates up to 120kBaud. The device operates from a single 5V supply with a quiescent supply current of 220µA. It utilizes an internal charge pump requiring four 0.1µF capacitors for voltage generation. The component provides ESD protection exceeding ±10kV and allows driver outputs and receiver inputs to be forced to ±25V without damage. It is housed in a 16-lead SOIC narrow package.
