MAX221EAE

Drivers, Receivers, Transceivers Overview

The MAX221EAE is a single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in an SSOP-16 surface-mount package. It operates at a fixed supply voltage of 5 V with a typical operating current of 10 mA. The device supports full-duplex communication with a maximum data rate of 250 kb/s and features a propagation delay of 0.15 µs. It includes one driver and one receiver, offering 15 kV ESD protection. The component functions within a temperature range of -40°C to +85°C and incorporates an auto-shutdown feature for power management.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a single RS-232 transceiver with built-in auto-shutdown capability for reduced power consumption during idle states.
• Provides robust electrostatic discharge protection rated at 15 kV to enhance signal integrity in noisy environments.
• Supports full-duplex data transmission at speeds up to 250 kb/s using a single 5 V power supply.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial communication interfaces
• Portable battery-powered equipment utilizing low-power shutdown modes
• Embedded systems connecting microcontrollers to RS-232 peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats such as tube or reel may vary between part numbers like MAX221EEAE+ and MAX221EAE+T. Confirm availability status directly with authorized distributors, as supply constraints can affect lead times. Ensure the selected variant matches the required package type and environmental rating for the target application.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring a single-channel RS-232 interface with minimal external components. The fixed 5 V operation simplifies power design compared to dual-supply alternatives. Consider the SSOP-16 footprint for PCB layout constraints. Verify that the 250 kb/s data rate meets system requirements, as higher-speed variants exist within the family.

Drivers, Receivers, Transceivers Part Context

The MAX221EAE belongs to the Maxim Integrated MAX221 series of single RS-232 transceivers. This family is designed for low-power applications where space and energy efficiency are critical. The device integrates charge pumps internally, eliminating the need for external capacitors typically required in older RS-232 solutions. It serves as a compact interface solution for legacy serial communication protocols.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MAX221EEAE+ (tube packaging) and MAX221EAE+T (reel packaging). These variants share identical electrical characteristics and pinouts but differ in shipping configuration. Cross-referencing with other single-driver RS-232 transceivers requires verifying voltage compatibility and shutdown functionality.
