MAX204EWE+

Drivers, Receivers, Transceivers Overview

The MAX204EWE+ is a +5V-powered, multichannel RS-232 driver designed for EIA/TIA-232E and V.28 communications interfaces. It features four drivers with no receivers, operating from a single +5V supply via integrated charge pump circuitry that eliminates the need for external bipolar supplies. The device supports data rates exceeding 120kbps and operates within an extended temperature range of -40°C to +85°C. Packaged in a 16-pin Wide SOIC (SO-Wide-16), it requires four 0.1µF external capacitors for proper operation.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar voltage sources.
• Four independent drivers provide TTL/CMOS-compatible inputs and maintain ±5V output signal levels under load.
• Includes internal 400kΩ pullup resistors on driver inputs to simplify unused pin handling.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature rating. Confirm the 'W' indicates the Wide SOIC package variant. Ensure the '+' suffix denotes lead-free compliance. Cross-reference the manufacturer's latest documentation for any obsolescence notices or alternate packaging options.

Drivers, Receivers, Transceivers Selection Notes

Select this component when only transmitter functionality is required for RS-232 communication. It is suitable for applications needing four channels but lacking receiver requirements. Consider the Wide SOIC package dimensions against available PCB space. Verify that the system can accommodate the necessary four external 0.1µF capacitors for the charge pump.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. While other members like the MAX202 include both drivers and receivers, the MAX204 specifically provides four drivers without receivers. This specialization allows for targeted integration in systems where multiple transmission lines are needed without receiving logic.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX202CWE+ serves as a functional substitute if two receivers are also required, though it has fewer drivers. The MAX204CWE+ is the commercial grade equivalent with a 0°C to +70°C range. Direct pin-for-pin replacement is possible with other MAX20x series drivers, provided the receiver count matches the design needs.
