MAX241EAI

MAX241EAI Description

The MAX241EAI from Analog Devices Inc./Maxim Integrated is a full-duplex RS-232 transceiver designed for robust serial communication in demanding environments. Housed in a 28-pin SSOP package, this obsolete but historically significant IC supports 4 drivers and 5 receivers, enabling versatile interfacing with peripherals. Operating within a 4.5V to 5.5V supply range, it delivers a data rate of 120Kbps, making it suitable for moderate-speed industrial and embedded systems. The device features 500mV receiver hysteresis, enhancing noise immunity in electrically noisy settings. Compliant with EAR99 and REACH Unaffected standards, it meets regulatory requirements for global deployment.

MAX241EAI Features

• High Integration: Combines 4 drivers and 5 receivers in a compact 28SSOP, reducing board space.
• Noise Resilience: 500mV hysteresis minimizes false triggering in high-interference environments.
• Wide Voltage Range: Operates from 4.5V to 5.5V, compatible with standard 5V logic systems.
• Full-Duplex Communication: Enables simultaneous bidirectional data flow for efficient RS-232 protocols.
• Industrial Robustness: MSL 1 (Unlimited) moisture sensitivity ensures reliability in varied storage conditions.
• Legacy Compatibility: Ideal for maintaining or upgrading older RS-232-based systems.

MAX241EAI Applications
