SC-B1420
Series
Frequency Range: 1.0 MHz to 80.0 MHz
Description
The SC-B1420 Series of quartz crystal oscillators provide enable/disable 3ꢀstate LVCMOS compatible signals
for bus connected systems. Supplying Pin ± of the SCꢀB±420 units with a logic “±” or open enables its Pin 3
output. In the disable mode, Pin 3 presents a high impedance to the load.
