ECS-300C SERIES DUAL OUTPUT CMOS CLOCK OSCILLATOR
The ECS-300C utilizes a built in divider
circuit to provide a second divided output.
The CMOS based oscillator features low
current consumption in a standard 8-pin
DIP package.
FEATURES
• Low current consumption
• Built in divider circuit
• 8-pin DIP package
