SJ-A1450 Series
Description
The SJ-A1450 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-A1450 units with a logic “1" or open enables its pin 3 output. In the disabled mode, pin 3 presents a high impedance to the load. All units are designed to survive wave soldering operations without damage.
Features
• Wide frequency ra.
