DS1620
User–defined temperature settings are stored in nonvolatile memory, so parts can be programmed prior to
insertion in a system, as well as used in standalone applications without a CPU. Temperature settings and
temperature readings are all communicated to/from the DS1620 over a simple 3–wire interface.

DESCRIPTION
Data Input/Output pin for 3-wire communication port.
Clock input pin for 3-wire communication port. When the DS1620 is used in a
stand-alone application with no 3–wire port, this pin can be used as a convert
pin. Temperature conversion will begin on the falling edge of CONV .
Reset input pin for 3-wire communication port.
Ground pin.
High/Low Combination Trigger . Goes high when temperature exceeds TH;
will reset to low when temperature falls below TL.
Low Temperature Trigger. Goes high when temperature falls below TL.
High Temperature Trigger. Goes high when temperature exceeds TH.
Supply Voltage. 2.7V – 5.5V input power pin.
