ECS-400X
SERIES
CLOCK OSCILLATOR
The ECS-400X Series clock oscillator offers
low current drain and is compatible with
HCMOS/TTL logic. The metal package with
pin #7 case ground acts as shielding to
minimize radiation.
FEATURES
• HCMOS/TTL logic compatible
• Wide frequency range
• Low power consumption
• Resistance weld package
• 3.3V operation (optional)
• PbFree/RoHS Compliant
