TTL
HS-1520 Series
Description
The
HS-1520 Series
of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for
bus connected systems. Supplying Pin 1 of the HS-1520 units with a logic “1" enables its output on Pin 8.
In the disabled mode, Pin 8 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 85.0MHz
User specified tolerance available
Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
