CISSOID is market leader in extreme temperature and extended lifetime semiconductor solutions

These products have now entered the End-of-Life stage.
See Last Time Buy details.
CISSOID high temperature products are guaranteed to operate reliably and within specifications:
- from -55°C to +225°C for the CHT family
- from -55°C to +175°C for the CMT family
- from -40°C to +175°C for the CXT family
Extreme tests by independent organizations, such as NASA and Sandia National Labs, demonstrated reliable operation from -195°C to +400°C over extended periods of time.
The expected lifetime of our products is 15 years at 175°C and 5 years at 225°C.
