DS1481 Overview
The device is normally used in conjunction with a parallel port controller to provide the necessary interface to the host processor. Busy signals allow the host processor to perform other tasks while 1 wire “time slots” are pleted. The DS1481 also saves the state of D/CLK and RES allowing print spoolers to operate without affecting 1 wire munication.
