SC-142B - ETC

SC-142B CRYSTAL CLOCK OSCILLATORS

The SC-1420 Series of quartz crystal oscillators provide enable/disable 3-state CMOS compatible signals for bus connected systems. Supplying Pin 1 of the SC-1420 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. Features • Wide frequency range–1.0MHz to 80.0MHz • User specified toleran.
