CRYSTAL CLOCK OSCILLATORS CMOS Compatible Enable, Disable Data Sheet 0016J Rev. E HA-A1370, A1380 Series Description The HA-A1370 Series of quart- 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
