TTL Compatible
Enable/Disable
HS-1200/1210 Series
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.
