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.

DETAILED PIN DESCRIPTION Table 1
PIN
SYMBOL
DESCRIPTION
1
DQ
Data Input/Output pin for 3-wire communication port.
2
CLK/ CONV
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 .
3
RST
Reset input pin for 3-wire communication port.
4
GND
Ground pin.
5
TCOM
High/Low Combination Trigger. Goes high when temperature exceeds TH;
will reset to low when temperature falls below TL.
6
TLOW
Low Temperature Trigger. Goes high when temperature falls below TL.
7
THIGH
High Temperature Trigger. Goes high when temperature exceeds TH.
8
VDD
Supply Voltage. 2.7V – 5.5V input power pin.
