MAX233ACPP

Overview

The MAX233ACPP is a +5V-powered, multichannel RS-232 driver and receiver from the MAX220–MAX249 family. It features an integrated charge pump that eliminates the need for external bipolar ±12V supplies, enabling single-supply operation. The device includes internal capacitors, saving printed circuit board space. It supports EIA/TIA-232E and V.28/V.24 interfaces with a data rate of up to 120 kbps. The AC suffix indicates an operating temperature range of 0°C to +70°C. It operates on a +5V supply (±5% tolerance) and provides TTL/CMOS compatible inputs and outputs.

Feature Summary

• Integrated charge pump circuitry generates internal ±10V voltages from a single +5V supply
• Internal capacitors eliminate the requirement for external components
• Supports bidirectional data communication at rates up to 120 kbps
• Provides low-power shutdown mode to reduce power dissipation

Applications

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

Procurement Notes

Verify the component matches the specific package type and temperature grade indicated by the suffix. Confirm the manufacturer origin as Analog Devices Inc./Maxim Integrated. Ensure the part number corresponds to the exact pinout and electrical specifications required for the design.

Selection Notes

Select this component when board space is limited due to the absence of external capacitors. It is suitable for applications requiring single +5V supply operation without generating negative voltages externally. Verify that the 120 kbps data rate meets the system requirements.

Part Context

This device belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E communications. The family offers various channel configurations and packages. The MAX233 specifically integrates all necessary capacitors internally for compact designs.

Replacement Considerations

Compatible substitutes within the same family include the MAX232A and MAX233A. These parts share similar electrical characteristics and functionality but may differ in manufacturing revisions or specific package availability.
