MAX3325CNI

Overview

The MAX3325CNI is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features an integrated dual charge pump that automatically powers up upon application of VCC within the 3.0V to 3.6V range, eliminating the need for external control pins or additional components. The device provides two drivers and two receivers in a 28-pin PDIP package, designed for serial communication applications requiring reliable data transmission.

Feature Summary

• Integrates dual charge pumps that activate automatically upon power-up without external control requirements
• Provides full-duplex RS-232 communication capabilities with two drivers and two receivers
• Operates within a standard 3.0V to 3.6V supply voltage range

Applications

• Serial communication systems
• Industrial equipment interfaces
