MAX250ESD+T

Overview

The MAX250ESD+T is a dual RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 14-pin SOIC package. It operates at a single +5V supply voltage and supports data rates up to 116kb/s with full-duplex communication capability. The device integrates two drivers and two receivers, featuring internal charge pumps that eliminate the need for external capacitors. Designed for industrial environments, it functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external positive and negative voltage generation components.
• Supports full-duplex data transmission compliant with EIA/TIA-232-F standards.
• Includes shutdown mode functionality to minimize power consumption during idle periods.

Applications

• Industrial control systems requiring reliable serial communication
• Point-to-point data transmission links
• Modem interface circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the '+' suffix indicating lead-free compliance and RoHS adherence. Ensure the SOIC-14 package matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring isolated RS-232 interfaces powered exclusively by a single +5V rail. It is suitable for applications needing moderate data speeds without the complexity of external biasing networks. Consider thermal dissipation limits if operating near maximum ambient temperatures.

Part Context

This part belongs to the MAX250/MAX251 family of high-performance RS-232 transceivers. The MAX250 variant specifically provides dual driver and receiver channels. It serves as a standard solution for legacy serial port implementations in embedded systems and industrial equipment where space efficiency and simplified power management are critical design constraints.

Replacement Considerations

Compatible alternatives include the MAX232 series and MAX3232 series. Verify pin compatibility and electrical specifications such as drive strength and data rate capabilities before substituting.
