temperature falls below TL. Thus, any hysteresis can be realized for fan control without external

components.

Digital data is written to/read from the DS1721 via a 2-wire interface, and all communication is MSb

first. Multipoint sensing is possible with the DS1721 by uniquely setting the 3-bit address of up to eight

parts on the 2-wire bus.
