Description
The HS-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for
bus connected systems. Supplying Pin 1 of the HS-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
