MAX230EPP+

Overview

The MAX230EPP+ is a +5V-powered, multichannel RS-232 driver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended temperature range of -40°C to +85°C and utilizes a 20-pin Wide SOIC package. The device provides five independent drivers with zero receivers, supporting data rates up to 120 kbps. It functions on a single +5V supply voltage, drawing a typical operating current of 15 mA. The component includes a shutdown feature for power reduction and incorporates an internal charge pump to generate the necessary ±10V levels without requiring external bipolar supplies.

Feature Summary

• Integrates a dual charge-pump DC-DC voltage converter to generate internal ±10V rails from a single +5V input
• Provides five independent RS-232 transmitter channels for multidrop network applications
• Includes a dedicated shutdown control pin to minimize power consumption in standby modes

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostics equipment lacking bipolar power supplies

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status directly with the supplier or through the datasheet's ordering information table before procurement.

Selection Notes

Select this component when a design requires multiple RS-232 transmit channels but does not need receiver functionality. Ensure the application supports the 120 kbps maximum data rate and fits within the specified -40°C to +85°C operating temperature range.
