1. When using Vout1 fH21 is clocked identically with fH2 while fH22 is held at a static level. When using Vout2 fH21 and fH22 are exchanged

so that fH22 is identical to fH2 and fH21 is held at a static level. The static level should be the same voltage as fH2 low.

2. The AC and DC operating levels are for room temperature operation. Operation at other temperatures may require adjustments of these

voltages. Pins shown with impedances greater than 1 MW are expected resistances. These pins are only verified to 1 MW.

3. fV1, 2 capacitances are accumulated gate oxide capacitance, and so are an over-estimate of the capacitance.

4. This device is suitable for a wide range of applications requiring a variety of different operating conditions. Consult ON Semiconductor in

those situations in which operating conditions meet or exceed minimum or maximum levels.

1. 50% duty cycle values.

2. CTE may degrade above the nominal frequency.

3. Rise and fall times (10/90% levels) should be limited to 5−10% of clock period. Crossover of register clocks should be between 40−60% of

amplitude.

4. fR should be clocked continuously.
