MAX230EPP

Overview

The MAX230EPP is a +5V-powered, multichannel RS-232 driver manufactured by Analog Devices/Maxim Integrated. It operates on a single +5V supply and utilizes an internal charge pump to generate the required ±10V for RS-232 signaling. The device features five drivers with no receivers included. It supports data rates up to 120 kbps and includes a shutdown mode that reduces power consumption significantly. The component is housed in a 20-pin Plastic DIP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual charge-pump circuitry to eliminate the need for external bipolar supplies
• Enables single-supply operation from a standard +5V source
• Includes a low-power shutdown mode to minimize energy consumption

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostics equipment requiring reduced power profiles

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm the exact package type and temperature grade. Confirm RoHS compliance status and production availability directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple RS-232 transmit channels without receiving capabilities. Ensure the application environment stays within the specified -40°C to +85°C operating range. Verify that the 120 kbps data rate meets the system requirements and that the 20-pin DIP footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers/receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. Unlike many peers in this series that include both drivers and receivers, the MAX230 variant specifically provides only transmitter functionality, making it suitable for unidirectional transmission applications.

Replacement Considerations

Consider the MAX230EWP+ as a surface-mount alternative offering identical electrical characteristics in a SOIC-20 package. Other family members like the MAX232 provide similar driver counts but differ in receiver configurations and pinouts.
