MAX232CEASE+T

Overview

The MAX232CEASE+T is a dual driver/receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. Designed for EIA/TIA-232-E and V.28/V.24 applications, it operates on a single +5V power supply with a voltage range of 4.5V to 5.5V. The device features two drivers and two receivers supporting full-duplex communication at data rates up to 120 kb/s. It utilizes an internal charge pump requiring four external capacitors to generate ±10V levels. Operating temperatures range from -40°C to +85°C, and the component is housed in a 16-pin SOIC package.

Feature Summary

• Integrates dual drivers and receivers for full-duplex serial communication
• Generates required RS-232 voltage levels using a single +5V supply via internal charge pump
• Compatible with standard TTL and CMOS logic families

Applications

• EIA/TIA-232-E and V.28/V.24 communications interface applications
• Embedded systems requiring serial port connectivity
• Industrial control equipment interfacing

Procurement Notes

Verify the specific suffix 'C' against official manufacturer documentation to confirm commercial grade temperature rating and exact electrical specifications. Confirm RoHS compliance status through current datasheets. Ensure the SOIC-16 package matches PCB footprint requirements before procurement.

Selection Notes

Select this component when designing systems requiring standard RS-232 signaling with a single +5V power source. It serves as a direct replacement for legacy MAX232 designs. Verify that the 120 kb/s data rate meets application needs. Consider thermal management within the industrial temperature range if operating near limits.

Part Context

This part belongs to the Maxim MAX232 family, which established the architecture for single-supply RS-232 transceivers. The series eliminates the need for complex dual-polarity power supplies by integrating charge pumps. This specific variant maintains the core functionality while adhering to commercial temperature specifications.
