MAX223EAI

Drivers, Receivers, Transceivers Overview

The MAX223EAI is a +5V-powered, multichannel RS-232 transceiver from the Analog Devices/Maxim Integrated MAX220–MAX249 family. It integrates four drivers and five receivers for full-duplex communication. The device operates on a single +5V supply, utilizing internal charge-pump circuitry to generate the required ±10V levels without external bipolar supplies. It supports data rates up to 120 kbps with a typical propagation delay of 40 µs. The component features a shutdown mode that reduces operating current to 15 mA. It is housed in a 28-pin SSOP package and is designed for EIA/TIA-232E and V.28/V.24 interfaces.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge-pump DC-DC voltage converters to eliminate the need for external bipolar ±12V power supplies.
• Enables single-supply operation from a +5V source while generating necessary internal voltage levels.
• Includes integrated capacitors to minimize printed circuit board space requirements.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates the industrial temperature range (-40°C to +85°C) and the 'I' denotes the SSOP package. Confirm RoHS compliance status as older manufacturing runs may differ. Check for lead-free soldering compatibility if reflow processes are used. Ensure the ordering code matches the exact pinout and functional specifications required for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple RS-232 channels within a compact footprint. It is suitable for applications where space is critical due to its integrated capacitor design. Verify that the 120 kbps data rate meets system timing requirements. Consider the 15 mA shutdown current for low-power standby modes. Ensure the +5V supply voltage remains within the specified tolerance for proper charge-pump operation.

Drivers, Receivers, Transceivers Part Context

The MAX223EAI belongs to the broader MAX220–MAX249 family of line drivers and receivers. This family provides various configurations of drivers and receivers to suit different interface needs. The MAX223 specifically offers a high channel count with integrated passive components. It shares common architectural features with other members like the MAX220 and MAX232 but differs in pin count and channel distribution.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include HIN211EIAZ and HIN213EIAZ from Renesas Electronics Corporation. These parts are listed as parameter equivalents in distributor databases. Verify pin-to-pin compatibility and electrical specifications before substitution.
