CMOS
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 253C
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
High Q Crystal actively tuned oscillator circuit
Power supply decoupling internal
No internal PLL avoids cascading PLL problems
Low power consumption
Gold plated leads - Solder dipped leads available
upon request
CMOS and TTL output levels
RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
