MAX232CSE+TGA8

Overview

The MAX232CSE+TGA8 is a +5V-powered, multichannel RS-232 driver/receiver from the Analog Devices/Maxim Integrated MAX220–MAX249 family. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 120kbps. The device features two drivers and two receivers for full-duplex communication. It utilizes an internal charge pump circuitry to generate ±10V levels from a single +5V supply, eliminating the need for external bipolar supplies. The component is housed in a 16-pin Narrow SO package and is rated for operation between 0°C and +70°C.

Feature Summary

• Integrates dual charge-pump DC-DC voltage converters to generate required RS-232 voltage levels internally
• Enables single-supply operation by converting +5V input to ±10V without external bipolar power sources
• Provides full-duplex signal transmission and reception through dedicated transmitter and receiver channels

Applications

• Interface translation for EIA/TIA-232E and V.28/V.24 communications interfaces
• Multidrop RS-232 network connections
• Portable diagnostics equipment requiring low-power serial communication

Procurement Notes

Verify that the ordering suffix corresponds to the specific temperature grade and packaging configuration required for the target application. Confirm the presence of lead-free compliance markings on the component body or documentation. Ensure the supplier provides traceability records matching the manufacturer's lot codes to guarantee authenticity and quality standards.

Selection Notes

Select this component when designing systems limited to a single +5V power rail where generating negative voltages is impractical. It is suitable for applications requiring moderate data rates up to 120kbps with standard noise immunity. Consider alternative models within the MAX220-MAX249 family if integrated capacitors or higher data rate capabilities are necessary for the specific design constraints.

Part Context

This part belongs to the MAX220–MAX249 series of +5V-powered multichannel RS-232 drivers and receivers. The series offers various configurations including different numbers of drivers and receivers, as well as options with integrated capacitors to save board space. The MAX232 variant specifically provides a balanced 2-driver, 2-receiver architecture commonly used in general-purpose serial interface designs.

Replacement Considerations

Compatible substitutes include other members of the MAX220-MAX249 family such as the MAX232A or MAX232EESE+, provided they match the required pinout and electrical specifications. Verify that any replacement maintains the same package type and operating temperature range to ensure mechanical and thermal compatibility.
