MAX202EUE

Drivers, Receivers, Transceivers Overview

The MAX202EUE is a dual RS-232 transceiver from the MAX200-MAX209 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply using an integrated charge pump to generate ±10V internal rails. The device features two drivers and two receivers with data rates up to 120kbps. It utilizes four external 0.1µF capacitors for voltage conversion. The E-suffix indicates an extended temperature range of -40°C to +85°C. The U suffix denotes a 16-pin TSSOP package.
