CRYSTAL CLOCK OSCILLATORS
Rev. M
CMOS Compatible Enable/Disable
HA-1380 Series
Description
The HA-1380 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying pin 1 of the HA-1380 units with a logic “1" enables its Pin 5 output.
In the disabled mode, Pin 5 presents a high impedance to the load. All units are resistance welded in an all
metal package, offering RFI shielding, and are designed to survive standard wave soldering operations
without damage. Insulated standoffs to enhance board cleaning are standard.
Features
• Wide frequency range– 0.5MHz to 36MHz
• User specified tolerance available

• High Q Crystal actively tuned oscillator circuit
• Will withstand vapor phase temperatures of 253°C • Power supply decoupling internal
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
package
• No internal PLL avoids cascading PLL problems
• Low power consumption
• Gold plated leads - Solder dipped leads available
upon request
