DESCRIPTION
The DS1481 is a dedicated 1-Wire
timing generator. 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 completed. The DS1481 also saves
the state of D/CLK and RES, allowing print spoolers to operate without affecting 1-Wire communication.
DS1481 based devices can be cascaded. The first device’s O1/BSY1 and O2/BSY2 connect to the PC
printer port’s BUSY and SELECT OUT signals (pins 11 and 13 respectively). The next DS1481 connects
its O1/BSY1 and O2/BSY2 to the first device’s I1 and I2 respectively. ENO of the first device connects
to ENI of the second device. More DS1481s can be stacked in a similar manner. The last device’s I1 and
I2 connect to BUSY and SELECT of the attached printer.
