SURFACE MOUNT HCMOS/TTL OSCILLATOR
The KFO90AT, a plastic encased surface mount oscillator, maintains
the same land pattern as our FSO series, but with smaller overall
dimensions. This reliable J-leaded component drives up to 10TTL
gates or a 50pF HCMOS load, and offers low current consumption
and tight symmetry.

* Inclusive of 25ºC tolerance, operating temperature range, input voltage change, load change, aging, shock, and vibration.
*** An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open.
Note: A 0.01 µF bypass capacitor should be placed between V
DD
(Pin 4) and GND (Pin 2) to minimize power supply line noise.
