HALF SIZE HCMOS/TTL HEAVY LOAD OSCILLATOR
F3020
The F3020 Clock Oscillator is our half size design capable of driving
heavy HCMOS loads. This oscillator has a tri-state enable/disable
on pin 1 to facilitate testing withATE. The package is all metal with
pin 4 as case ground which provides shielding to help minimize EMI
radiation.
