MAX230CPP+

Overview

The MAX230CPP+ is a +5V-powered, multichannel RS-232 driver from the Analog Devices/MAXIM MAX220–MAX249 family. It provides five drivers and zero receivers in a 28-pin Plastic DIP package. The device operates at data rates up to 120 kbps with a typical supply current of 15 mA. It functions within an extended temperature range of -40°C to +85°C. The integrated charge pump eliminates the need for external bipolar supplies.

Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation without requiring external bipolar voltage sources.
• Provides five independent RS-232 transmitter channels for multidrop network applications.
• Features low-power shutdown mode to minimize energy consumption when the interface is inactive.

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostics equipment

Procurement Notes

Verify the specific suffix CPP against official manufacturer documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require multiple serial ports but lack negative voltage rails. The integrated charge pump simplifies board layout by removing external capacitors typically needed for voltage inversion. Verify that the 120 kbps data rate meets the application's throughput requirements.

Part Context

This part belongs to the MAX220–MAX249 series of line drivers/receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The series offers various channel counts and packages to address different space and power constraints in industrial and commercial electronics.

Replacement Considerations

Compatible substitutes include other members of the MAX220–MAX249 family, such as the MAX232 or MAX249, provided they match the required number of drivers and package dimensions.
