MAX204EWE+T

Drivers, Receivers, Transceivers Overview

The MAX204EWE+T is a +5V-powered, four-driver RS-232 transceiver from the MAX200-MAX209 family. It integrates charge-pump circuitry to generate ±10V internal supplies from a single +5V source, eliminating external bipolar rails. The device features four TTL/CMOS-compatible drivers and operates at data rates exceeding 120kbps. It utilizes a 16-pin Wide SOIC package with an industrial temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual charge pumps for voltage doubling and inversion to create internal ±10V rails from a single +5V supply.
• Provides four independent RS-232 drivers with TTL and CMOS input compatibility.
• Includes internal 400kΩ pullup resistors on driver inputs to ensure low-power shutdown states when inputs are unconnected.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring single-supply operation
• Handheld diagnostic tools
• Portable instrumentation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the specified Wide SOIC package and temperature grade. Ensure all required external capacitors are selected according to datasheet specifications for stable charge-pump performance.

Drivers, Receivers, Transceivers Selection Notes

Select this part when four serial drivers are required within a compact footprint. The integrated charge pump simplifies design by removing the need for negative voltage generators. Verify that the application environment remains within the specified -40°C to +85°C operating range for reliable signal integrity.

Drivers, Receivers, Transceivers Part Context

This component belongs to the Maxim Integrated MAX200-MAX209 series of +5V RS-232 transceivers. These devices share a common architecture utilizing internal charge pumps to achieve EIA/TIA-232E compliance without external bipolar power supplies, targeting space-constrained portable electronics.

Drivers, Receivers, Transceivers Replacement Considerations

MAX202EWE+T offers two drivers instead of four. MAX206EWE+T provides four drivers but includes receiver outputs and enable/shutdown control pins not present in the MAX204.
