The F3000 Clock Oscillator is capable of driving heavy HCMOS

loads. This oscillator has a tri-state enable/disable function on pin

1 to facilitate testing with ATE. The package is all metal with pin 7

as case ground which provides shielding to help minimize EMI

radiation.

FEATURES

• 50pF HCMOS Load to 80 MHz

• 10TTL Fanout

• Tri-State Enable/Disable

All dimensions are in millimeters.
