MAX241EWI-T

Overview

The MAX241EWI-T is a low-power, +5V-powered multichannel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates four drivers and five receivers to support full-duplex communication with a data rate of 120 kb/s. The device operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating current of 15 mA. It features a shutdown mode for power conservation and is housed in a 28-pin SO-Wide package. The component supports an operating temperature range from -40°C to +85°C and includes a propagation delay of 10 µs.

Feature Summary

• Integrates four independent drivers and five receivers for comprehensive RS-232 connectivity
• Includes a dedicated shutdown pin to minimize power consumption during idle periods
• Designed for single-supply +5V operation with internal charge pump circuitry

Applications

• Industrial control systems requiring serial communication interfaces
• Portable instrumentation and battery-operated devices
• Modem and communications equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the supplier provides traceability certificates matching the Analog Devices manufacturing standards. Cross-reference the part number against the latest product change notices to verify current production status.

Selection Notes

Select this component when designing systems that require multiple RS-232 channels on a single +5V supply. It is suitable for applications prioritizing low power consumption due to its integrated shutdown feature. Compare driver/receiver counts against system requirements to ensure the four-driver and five-receiver configuration meets interface needs without excess component count.

Part Context

This part belongs to the MAX241 series of RS-232 transceivers, which are designed for high-performance serial communication. The series is characterized by its ability to operate from a single 5V supply while generating the necessary higher voltages for RS-232 signaling internally. It serves as a standard interface solution for microcontrollers and DSPs requiring robust serial data transmission.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX241EEWI+ if ESD protection is required, as the base MAX241 lacks specified ESD protection. Verify if the MAX202 series is suitable for systems requiring fewer channels but similar electrical characteristics.
