MAX233AEPP+G36

Overview

The MAX233AEPP+G36 is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and features integrated charge-pump circuitry with internal capacitors, eliminating the need for external components or bipolar ±12V supplies. The device provides full-duplex communication with two drivers and two receivers, supporting data rates up to 120kbps. It is housed in a 20-pin Plastic Dual In-Line Package (PDIP) and is rated for an extended industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors or bipolar power supplies
• Enables single-supply operation from a standard +5V source
• Provides EIA/TIA-232E compliant signal levels for reliable serial communication

Applications

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

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt as surface-mount or through-hole variants require specific handling. Ensure compliance with RoHS directives if required by the manufacturing environment. Cross-reference the ordering suffix with official documentation to confirm exact specifications.

Selection Notes

Select this component when board space is limited due to the absence of external capacitors. Verify that the application requires only two transmitter/receiver channels. Ensure the system operates within the specified +5V voltage tolerance. Consider the PDIP package constraints regarding thermal dissipation and physical footprint compared to surface-mount alternatives.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The 'A' designation indicates optimized electrical characteristics, while 'E' specifies the extended temperature range. The 'P' denotes the plastic DIP package, and '+G36' signifies lead-free packaging compliant with environmental standards.
