... CASCADE OPERATION A feature of the DS1801 is the ability to control multiple devices from a single processor. Multiple DS1801s can be linked or daisy-chained as shown in Figure data bit is entered into the I/O shift register of the DS1801, bit 0 of the I/O shift register will appear at the nanoseconds. The C output of the DS1801 can be used to drive the D input of another DS1801 ...
