• Up to Eight LM75s Can be Connected to a Single
LM75 provides 9-bit digital temperature readings with
Bus
an accuracy of ±2°C from -25°C to 100°C and ±3°C
over –55°C to 125°C.
• Power Up Defaults Permit Stand-alone Operation
as Thermostat
Communication is accomplished over a 2-wire
interface which operates up to 400kHz. The LM75
• UL Recognized Component (LM75B and LM75C)
has three address pins, allowing up to eight LM75
• Key Specifications:
devices to operate on the same 2-wire bus. The
– Supply Voltage
LM75 has a dedicated over-temperature output (O.S.)
– LM75B, LM75C: 3 V to 5.5 V
with programmable limit and hystersis. This output
has programmable fault tolerance, which allows the

user to define the number of consecutive error
– Operating: 280 μA (typical)
conditions that must occur before O.S. is activated.
– Shutdown: 4 μA (typical)
