NEL SJ-A1440

SJ-A1440
Series
LVCMOS
SJ-A1440 Series Rev P
Frequency Range: 10.0 MHz to 250.0 MHz
Description
The SJ-A1440 Series of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible signals
for bus connected systems. Supplying Pin 1 of the SJ-A1440 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.
