MAX236CNG+

Overview

The MAX236CNG+ is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of 0°C to +70°C and utilizes a 24-pin Plastic DIP package. The device integrates dual charge-pump DC-DC voltage converters that generate ±10V from a single +5V supply, eliminating the need for external bipolar supplies. It features four drivers and four receivers with TTL/CMOS-compatible inputs and outputs.

Feature Summary

• Integrates dual charge-pump circuitry to generate internal ±10V voltages from a single +5V supply
• Provides full RS-232 signal compatibility without requiring external bipolar power sources
• Includes dedicated enable control pins for selective transmitter and receiver activation

Applications

• Interface translation between TTL/CMOS logic and RS-232 serial ports
• Multidrop RS-232 network communication systems
• Portable diagnostic equipment utilizing single-supply operation

Procurement Notes
