MAX232ECSE+T

Overview

The MAX232ECSE+T is a dual-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +4.5V to +5.5V supply and includes an integrated charge pump to generate ±10V internal levels. The device provides two drivers and two receivers, supporting full-duplex communication at data rates up to 120kbps. It features high ±15kV ESD protection on all pins. The component is housed in a 16-pin Narrow SO package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar voltage sources.
• High electrostatic discharge protection rated at ±15kV Human Body Model for robust performance in harsh environments.
• Dual driver and receiver configuration supports simultaneous bidirectional serial data transmission.

Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools
• Portable instrumentation systems

Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and Narrow SO-16 package. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require reliable RS-232 communication with enhanced ESD immunity. Ensure the application environment remains within the specified 0°C to +70°C operating range. Verify that the system power supply maintains stability between +4.5V and +5.5V for optimal signal integrity.

Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. These devices are designed to convert TTL/CMOS logic levels to RS-232 voltages and vice versa. The 'E' designation indicates enhanced ESD protection capabilities compared to standard variants, making them suitable for applications involving frequent connector mating.

Replacement Considerations

Compatible substitutes include other MAX232 variants from the same family, such as MAX232EESE+T for extended temperature ranges. Ensure any replacement matches the 16-pin Narrow SO footprint and maintains equivalent electrical characteristics regarding supply voltage and data rate capabilities.
