MAX562EWI

Drivers, Receivers, Transceivers Overview

The MAX562EWI is a serial interface transceiver designed for notebook and palmtop computers, operating within a supply voltage range of 2.7V to 5.25V. It supports data rates up to 230kbps with a guaranteed slew rate of 4V/µs and meets EIA/TIA-562 standards. The device integrates three drivers and five receivers in a 28-pin SO package. Electrical characteristics include an operating supply current of 33mA at VCC = 3.3V with all outputs loaded, and a shutdown supply current of 1µA when both SHDN and EN are low. The component operates across a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge-pump voltage converter generates regulated positive and negative supplies for transmitter operation.
• Low-power shutdown and keep-awake modes allow for reduced power consumption while maintaining receiver activity.
• CMOS-compatible inputs and outputs ensure compatibility with standard logic levels.
• Flow-through pinout facilitates easy integration into existing circuit designs.

• Palmtop, Notebook, and Subnotebook Computers
• Peripherals
• Battery-Powered Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWI' confirms the extended temperature range (-40°C to +85°C) and SOIC-28 package type. Confirm RoHS compliance status as indicated by the '+' suffix if applicable. Check for obsolescence or lifecycle status through official manufacturer channels before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring EIA/TIA-562 compatibility with low-voltage operation. Ensure external capacitors meet the recommended specifications for the charge pump. Consider the 28-pin SO package constraints for PCB layout. Verify that the required data rate does not exceed 230kbps.

Drivers, Receivers, Transceivers Part Context

The MAX562 series includes variants like the MAX562CWI (commercial temperature) and MAX562CAI (SSOP package). The MAX562EWI specifically denotes the industrial temperature grade (-40°C to +85°C) housed in a standard 28-pin Small Outline (SO) package. This variant is part of Maxim Integrated's portfolio for serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must match the 230kbps data rate, 2.7V-5.25V supply range, and 3-driver/5-receiver configuration. Verify pinout compatibility for the 28-pin SO package. Check if alternative devices support the same EIA/TIA-562 electrical specifications and shutdown control logic.
