DS1482 - 1-Wire Level Shifter and Line Driver

General Description

The DS1482 is a simple 1-Wire line driver with load sensor and level shifter, designed to function as an interface between a 3V host system and a 1-Wire system that runs on 5V.

Two supplies are provided, a 5V supply for the 1-Wire operations (VCC) and an interface supply (VCCQ).

Key Features

  • PIN.
