MAX235EPG+

Overview

The MAX235EPG+ is a fully integrated RS-232 transceiver designed for single +5V supply operation. It features five drivers and five receivers, providing full-duplex communication capabilities without requiring external bipolar power supplies. The device incorporates an internal charge pump to generate the necessary ±10V levels from the single supply. It operates within a temperature range of -40°C to +85°C and is housed in a 24-pin Plastic DIP package.

Feature Summary

• Eliminates the need for external capacitors through integrated onboard components
• Enables single-supply operation by generating internal ±10V rails via charge pumps
• Provides comprehensive ESD protection on receiver inputs

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring space-constrained designs

Procurement Notes

Verify the specific suffix 'PG+' against the manufacturer's current product status documentation. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the 24-pin PDIP package dimensions align with your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when board space is critical due to its integrated capacitor design. It is suitable for applications requiring five independent channels of bidirectional data transfer. Verify that the system operates strictly at +5V, as the internal charge pump performance depends on this specific voltage level.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers. This series is specifically engineered for EIA/TIA-232E and V.28/V.24 interfaces where traditional dual-supply solutions are impractical. The MAX235 variant distinguishes itself by offering five driver/receiver pairs within a single integrated circuit.

Replacement Considerations

Public confirmed substitute part numbers: MAX235ACPE+, MAX235CPE+.
