TTL Compatible Enable/Disable
HA-1210 Series
Data Sheet 8820B
Rev. L
The HA-1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible signals for
bus connected systems. Supplying Pin 1 of the HA-1210 units with a logic “1" enables the output on Pin 5.
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.
