MAX208CDBRG4

Drivers, Receivers, Transceivers Overview

The MAX208CDBRG4 is a multichannel RS-232 line driver and receiver manufactured by Texas Instruments. It operates from a single 5-V supply and includes dual charge-pump circuits to generate the necessary positive and negative voltages for RS-232 signal levels without requiring external components. The device features four drivers and four receivers, providing full-duplex communication capabilities. It incorporates ±15-kV electrostatic discharge (ESD) protection on all RS-232 lines, enhancing reliability in harsh environments. The component is housed in a 24-pin SSOP package and is rated for operation within the commercial temperature range of 0°C to 70°C.
