OSCILLATORS OSCILLATORS
* Inclusive of 25˚C tolerance, operating temperature range, input voltage change, load change, aging, shock and vibration.
** An internal pullup resistor from pin 1 to pin 14 allows active output if pin 1 is left open.
The ECS-1000 Series clock oscillator can
drive both HCMOS and TTL logic. This
oscillator also features tri-state enable/disable
capabilities in a 14 pin DIP package.
FEATURES
• 50pF HCMOS/ TTL logic
• Tri-State enable/disable
• Wide frequency range
• Resistance weld package
• 3.3V operation (optional)
