CRYSTAL CLOCK OSCILLATORS
TTL Compatible Enable/Disable
HS-1200/1210 Series
Data Sheet 8706A
Rev. M
Description
The HS-1200/1210 Series of quartz crystal oscillators provide enable/disable 3-state TTL compatible
signals for bus connected systems. Supplying Pin 1 of the HS-1200 units with a logic “0" enables the output
on Pin 8. Alternately, supplying pin 1 of the HS-1210 units with a logic “1" enables its Pin 8 output. In the
disabled mode, Pin 8 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
