ADT7484A/ADT7486A
GENERAL DESCRIPTION
The ADT7484A/ADT7486A are simple digital temperature sensors
for use in PC applications with a Simple Serial Transport (SST)
interface. These devices can monitor their own temperature as
well as the temperature of one (ADT7484A) or two (ADT7486A)
remote sensor diodes. The ADT7484A/ADT7486A are controlled
by a single SST bidirectional data line. The devices are fixed-
address SST clients where the target address is chosen by the
state of the two address pins, ADD0 and ADD1.
