CRYSTAL CLOCK OSCILLATORS
Rev. E
CMOS Compatible Enable/Disable
HA-A1370/A1380 Series
Description
The HA-A1370 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-A1370 units with a logic “0" enables the output on
Pin 5. Alternately, supplying pin 1 of the HA-A1380 units with a logic “1" enables its Pin 5 output. In the
disabled mode, Pin 5 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.
