HA-A1440 Series
Data Sheet 0014A
Rev. F
Description
The HA-A1440 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-A1440 units with a logic “1" or open enables its pin 5
output. In the disabled mode, pin 5 presents a high impedance to the load.
Features
• Wide frequency range– 70.1MHz to 125.0MHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
