MAX230EWP

Overview

The MAX230EWP+ is a +5V-powered, multichannel RS-232 driver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 120kbps. The device features five drivers with zero receivers, housed in a 20-pin SOIC package. It requires four external capacitors (C1–C4) for its internal charge-pump circuitry. Operating temperatures span from -40°C to +85°C, with a typical supply current of 15mA under no-load conditions.

Feature Summary

Integrates dual charge-pump DC-DC converters to generate ±10V from a single +5V supply
Eliminates the need for bipolar ±12V power supplies in RS-232 applications
Provides five independent RS-232 transmitter channels for multidrop network interfaces

Applications

Interface translation between TTL/CMOS logic and RS-232 standards
Multidrop RS-232 communication networks
Portable diagnostic equipment requiring low-power serial connectivity

Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range (-40°C to +85°C). Confirm the '+' suffix indicates RoHS compliance. Ensure the 'WP' designation matches the required 20-pin Wide SOIC package dimensions. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity before procurement.

Selection Notes

Select this component when designing systems that require multiple RS-232 transmit lines but do not need receiver functionality. It is suitable for space-constrained designs where eliminating external voltage inverters is necessary. Verify that the application does not exceed the 120kbps data rate limit or draw excessive current from the V+ and V- pins, which could degrade output voltage levels.

Part Context

This device belongs to the MAX220–MAX249 family of +5V-powered RS-32 drivers and receivers. Unlike transceivers such as the MAX232, the MAX230 provides only transmitter channels. It shares the same internal charge-pump architecture as other family members but offers a higher channel count for multi-port serial applications.
