MAX1323ECM+

Analog To Digital Converters (ADC) Overview

The MAX1323ECM+ is a single-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 120 kbps. The device integrates charge pump circuitry to generate the required RS-232 voltage levels from a single power supply, eliminating the need for external capacitors in some configurations or reducing component count. It features full-duplex communication with one driver and one receiver. The component is housed in an 8-pin MiniSO package and is designed for industrial temperature ranges.

Analog To Digital Converters (ADC) Feature Summary

• Single RS-232 transceiver with integrated charge pump
• Operates on a single 3.0 V to 5.5 V power supply
• Data transmission rates up to 120 kbps
• Full-duplex operation with 1 driver and 1 receiver

Analog To Digital Converters (ADC) Applications

• Industrial control systems requiring serial communication
• Portable battery-powered equipment due to low supply voltage compatibility
• Modems and fax machines
• Point-of-sale (POS) terminals

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ECM+' against the manufacturer's current datasheet to confirm pinout compatibility and environmental compliance status. Ensure the source document explicitly lists the MAX1323ECM+ as an active or supported part number, as older Maxim products may have been discontinued or superseded by newer series variants. Cross-reference the package type (MiniSO-8) with your PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel RS-232 interface is needed with minimal external components. It is suitable for applications where space is constrained and a single 3V to 5V supply is available. Compare against the MAX1324E for quad-channel needs or MAX1348E for higher speed requirements if the 120 kbps limit is insufficient. Verify ESD protection ratings match the target environment specifications.

Analog To Digital Converters (ADC) Part Context

The MAX1323 belongs to the Maxim Integrated line of RS-232 transceivers, which are widely used in legacy and industrial serial communication interfaces. This specific model represents the single-driver/single-receiver variant in the family, often paired with multi-channel counterparts like the MAX1324E. The 'E' designation typically indicates an extended temperature range, while 'CM' refers to the plastic mini-small-outline package.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed direct substitutes include the MAX1323E (without the '+' suffix, noting lead-free differences) and potentially the MAX1323ESA for SOIC package variations. Check manufacturer cross-reference guides for exact functional equivalents, as pinouts must remain identical for drop-in replacement.
