MAX3230AEEWV+T

Overview

The MAX3230AEEWV+T is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for low-power applications. It operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 250 kbps. The device features full-duplex communication with two drivers and two receivers. It provides ±15 kV ESD protection on all pins and utilizes small form-factor packaging options including UCSP and WLP. The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrated ±15 kV electrostatic discharge (ESD) protection on all RS-232 signal pins.
• Capable of operating with a single charge pump requiring only external 0.1 µF capacitors.
• Supports full-duplex data transmission at speeds up to 250 kbps.

Applications

• Portable battery-powered equipment such as laptops and palmtop computers.
• Industrial control systems requiring robust serial communication interfaces.
• Handheld terminals and mobile data collection devices.

Procurement Notes

Verify the specific suffix 'EWV+T' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprint designs for the 30-WLP or UCSP package variants. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a small footprint compared to standard SSOP packages. Choose the MAX3230AEEWV+T over higher-speed variants if power consumption is critical, as it supports lower baud rates. Verify that the system voltage aligns with the 2.5 V to 5.5 V operating range for optimal performance.

Part Context

This part belongs to the MAX3230/MAX3231 family of low-power RS-232 transceivers. It shares functional similarities with the MAX3232 series but differs in pinout and package density. The device is often used in conjunction with other Maxim interface components for complete serial communication solutions in compact electronic designs.

Replacement Considerations

Direct substitutes include the MAX3230AE and MAX3230AEEWV+. Verify pin-to-pin compatibility and electrical parameters before substitution. Alternative packages like the UCSP variant may offer different thermal characteristics.
