HA-1450 Series
Description
The
HA-1450 Series
of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-1450 units with a logic “1" or open enables its pin 8
output. In the disabled mode, pin 8 presents a high impedance to the load. All units are designed to
survive wave soldering operations without damage.
Features
• Wide frequency range– 0.5MHz to 30.0MHz
• 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
package
• Low Jitter
