MAX241CWI+TG068

Overview

The MAX241CWI+ is a low-power, multichannel RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It integrates four drivers and five receivers to support full-duplex communication with data rates up to 120 kb/s. The device operates from a single +5V power supply and includes internal charge pumps that generate the required ±10V levels for RS-232 signaling without external components. Key electrical parameters include a maximum propagation delay of 10 µs, an operating supply current of 15 mA, and a shutdown mode for power conservation. It functions within a commercial temperature range of 0°C to +70°C and is housed in a 28-pin SO-Wide package.

Feature Summary

• Integrates dual charge pumps to generate RS-232 voltage levels internally
• Supports full-duplex communication with four drivers and five receivers
• Includes a shutdown mode to minimize power consumption during idle periods

Applications

• Industrial control systems requiring serial communication
• Point-of-sale terminals and handheld devices
• Modems and portable instrumentation

Procurement Notes

Verify the specific suffix 'TG068' against official manufacturer documentation, as standard datasheets typically list 'MAX241CWI+'. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production lot.

Selection Notes

Select this component when a single +5V supply is available and multiple RS-232 channels are needed. Ensure the 120 kb/s speed meets system requirements. Compare against the MAX223 for similar functionality or the MAX3241 if lower voltage operation is required. Verify package dimensions match the PCB footprint.

Part Context

This part belongs to the Maxim Integrated MAX241 family of RS-232 transceivers. It is designed for applications needing reliable serial communication in space-constrained environments. The device simplifies design by eliminating external capacitors for voltage generation, reducing board space and assembly complexity compared to older discrete solutions.

Replacement Considerations

The MAX223CWI+ offers similar functionality with four drivers and five receivers but has a higher propagation delay of 40 µs. For lower voltage applications, the MAX3241CWI+ supports 3V to 5.5V supplies. Verify pin compatibility and electrical specifications before substitution.
