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.
