Description
The HA-A1370 Seriesof quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the HA-A1370units with a logic “0" enables the output on Pin 5. Alternately, supplying pin 1 of the HA-A1380units 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.
