DS2482S-800+T&R

The DS2482S-800+T&R by Analog Devices (formerly Maxim Integrated) is an I2C-to-1-Wire bridge device designed for seamless integration between I2C microcontrollers and 1-Wire slave devices. This IC acts as a 1-Wire master relative to any attached 1-Wire slaves, supporting both standard (100kHz) and fast (400kHz) I2C communication speeds.

Key features include eight independently operated 1-Wire I/O channels, selectable active or passive 1-Wire pullup, and support for standard and overdrive 1-Wire communication speeds. Internal timers handle time-critical 1-Wire waveform generation, relieving the host processor. The device also incorporates slew-rate control for reduced line noise and programmable strong pullup features for power delivery to 1-Wire devices like EEPROMs and sensors. Three address inputs allow for flexible I2C slave address assignment.

This component is housed in a 16-pin SOIC package and operates over a wide temperature range of -40°C to +85°C. Its applications span wireless base stations, central office switches, rack-based servers, and medical clinical diagnostic equipment, making it a versatile solution for systems requiring mixed-protocol communication.

The DS2482S-800+T&R is suitable for designs needing to interface with various 1-Wire sensors and memory devices using an I2C bus. Its robust feature set, including slew-controlled edges and strong pullup capabilities, ensures reliable communication and signal integrity in demanding environments.
