    Products Detail

    The MAX253 is a monolithic oscillator/power-driver designed for isolated RS-485/RS-232 interfaces. It drives a center-tapped transformer primary from a 5V or 3.3V DC supply, providing isolated voltage up to 1W. The device consists of a CMOS oscillator driving a pair of N-channel power switches with break-before-make action. It features a shutdown pin for low-power mode (0.4µA) and a frequency select pin for 200kHz or 350kHz operation. Available in 8-pin DIP, SO, µMAX, and CERDIP packages.

    Key Features

    • Simple Power-Supply Transformer Driver Design for Isolated RS-485/RS-232 Data-Interface Applications
    • Single 5V or 3.3V Supply
    • Low-Current Shutdown Mode: 0.4µA
    • Pin-Selectable Frequency: 350kHz or 200kHz
    • 8-Pin DIP, SO, and µMAX Packages Take Minimal Board Space
    • Break-before-make action between switches
    • CMOS oscillator with N-channel power switches
