SJ-A1421-FREQ

SJ-A1420 Series LVCMOS SJ-A1420 Series Rev S Frequency Range: 1.0 MHz to 80.0 MHz Description The SJ-A1420 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals for bus connected systems. Supplying Pin 1 of the SJ-A1420 units with a logic “1” or open enables its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load. All units are designed to survive standard wave soldering operations without damage.
