HA-A1420 Series
Description
The
HA-A1420 Series
of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-A1420 units with a logic 鈥?" 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.
