Description

The HA-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals

for bus connected systems. Supplying Pin 1 of the HA-1420 units with a logic “1" or open enables its

output. In the disabled mode, output pin 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 85MHz

• User specified tolerance available

• Will withstand vapor phase temperatures of 253°C

• Space-saving alternative to discrete component

• High shock resistance, to 3000g

• All metal, resistance weld, hermetically sealed
