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 on-
board thermal sensing element and made available as an
8-bit digital word.

TC74
Communication with the TC74 is accomplished via a
simple 2-wire SMBus/I
2C-compatible serial port. This bus
also can be used to implement multi-drop/multi-zone moni-
toring. 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
A
(5
A Standby).
Small size, low installed cost, and ease of use make the
TC74 an ideal choice for implementing thermal manage-
ment in a variety of systems.
