MAX204CPE+

Drivers, Receivers, Transceivers Overview

The MAX204CPE+ is a +5V-powered RS-232 transceiver featuring four drivers and no receivers, designed for EIA/TIA-232E and V.28 communications interfaces. It utilizes an integrated charge pump to generate ±10V from a single +5V supply, eliminating the need for external bipolar power sources. The device supports data rates exceeding 120kbps with typical propagation delays of 10µs. Operating within a commercial temperature range of 0°C to +70°C, it draws a maximum operating supply current of 20mA. The component is housed in a 16-pin Wide Small-Outline (SO) package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates charge pump circuitry to enable single-supply operation without requiring bipolar voltage rails
• Provides four TTL/CMOS-compatible drivers for converting logic signals to RS-232 levels
• Includes internal pullup resistors on driver inputs to simplify unused pin handling

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power interface solutions
• Handheld devices with limited board space constraints
• Portable diagnostic equipment utilizing serial communication protocols

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in official datasheets. Ensure compatibility with existing PCB footprints for the 16-pin Wide SO package before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when only transmitter functionality is required for RS-232 interfacing. Verify that the application does not require receiver channels, as this part lacks them. Confirm that the single +5V supply capability meets the system power architecture requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX200–MAX209 family of +5V RS-232 transceivers. Unlike the MAX202 which includes two receivers, the MAX204 variant provides four drivers exclusively. This configuration suits applications needing multiple transmit lines but minimal receive paths.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX204CWE+ serves as a direct replacement offering the same electrical characteristics in a standard SO package.
