MAX235EPG+G36

Overview

The MAX235EPG+G36 is a fully integrated, +5V-powered RS-232 transceiver featuring five drivers and five receivers in a 24-pin PDIP package. It operates within a supply voltage range of 4.75V to 5.25V and supports data rates up to 120Kbps. The device incorporates an internal charge pump circuit that eliminates the need for external bipolar ±12V supplies, enabling single-supply operation. It provides receiver input hysteresis of 500mV and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual charge-pump DC-DC converters to generate required RS-232 voltage levels from a single +5V source
• Includes five independent drivers and five receivers for full-duplex communication
• Features built-in receiver hysteresis to improve noise immunity on serial lines

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring compact interface solutions
