General Description
The TC74 is a serially accessible digital temperature
sensor particularly suited for low cost and small form-
factor applications. Temperature data is converted from
the onboard thermal sensing element and made
available as an 8-bit digital word.
Communication with the TC74 is accomplished via a 2-
wire SMBus/I
2
C
compatible serial port. This bus also
can be
used to implement multi-drop/multi-zone
monitoring. The SHDN bit in the CONFIG register can
be used to activate the low power Standby mode.
Temperature resolution is 1°C. Conversion rate is a
nominal 8 samples/sec. Power consumption is only
200
μ
A typ, (5
μ
A Standby, typ).
Small size, low installed cost, and ease of use make the
TC74 an ideal choice for implementing thermal
management in a variety of systems.
