DS2480B+ Description

Short technical summary and product information.

The Analog Devices DS2480B+ is a versatile serial port to 1-Wire interface chip designed to simplify the integration of 1-Wire devices with RS-232 communication ports. This IC supports both standard and overdrive speeds for 1-Wire communication, offering data rates from 9.6kbps up to 115.2kbps.

 

Key features include a self-calibrating time base with ±5% tolerance for reliable serial and 1-Wire communication. It operates over a voltage range of 4.5V to 5.5V and is rated for an industrial temperature range of -40°C to +85°C. The DS2480B+ is housed in a compact 8-SOIC surface-mount package, making it suitable for various embedded applications.

 

This chip simplifies the design of low-cost, universal RS-232 COM port to 1-Wire interfaces. It works with bipolar and unipolar logic signals, and features slew rate controlled pulldown and active pullup for long line accommodation and reduced radiation. The user-selectable RXD/TXD polarity minimizes component count when interfacing to 5V RS232 systems or directly to UARTs. Its smart protocol combines data and control information without requiring extra pins, enhancing system integration with various iButton or 1-Wire device types.
