HA-1450 Series
Description
The
HA-1450 Series
of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals
for bus connected systems. Supplying Pin 1 of the HA-1450 units with a logic 鈥?" or open enables its pin 8
output. In the disabled mode, pin 8 presents a high impedance to the load. All units are designed to
survive wave soldering operations without damage.
