Description
Owing to their small size, light weight, and
rugged characteristics, these 5.0V 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 four 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
Applications that require an HCMOS5.0V clock
and might be exposed to extremely harsh
environmental conditions.
