All units are vacuum baked before sealing at 175°C for
16 hours to eliminate moisture traces and pre-age units
for superior stability
Description
Owing to their small size, light weight, and
rugged characteristics, these 3.3V HCMOS
extended temperature/COTS oscillators fulfill
tasks not previously feasible. They are used in
applications that take advantage of their
extended temperature range and high
performance. Twenty six different models
(with and without tristate) cover -55°C to
+200°C operation and provide frequency
selection from 20KHz to 100MHz. They
combine excellent long-term reliability, loading
characteristics, and superior startup
performance.

Applications
¾
Any electronic circuit requiring 3.3V HCMOS
clocking that is exposed to very high or very low
temperatures such as oil drilling or weather
observation equipment
