OUTPUT DRIVE
Dual push-pull outputs OutA and OutB are provided for driving off chip switches. The output stages are identical:
Totem Pole configuration
Break-before-make switching to prevent harmful cross-conduction spikes
Separate positive and negative supply connections to decouple power stage and sensitive logic
Near rail-to-rail voltage swing
±1A maximum peak current capability (capacitive load)
The outputs have two modes of control depending on whether the 50% toggle option is selected. In the case where the
50% pin is logic low, the outputs are in-phase with each other and the duty cycle is free to take on any value up to 100%.
However, when the 50% pin is asserted high (logic ''1''), the outputs become limited to a maximum 50% duty cycle by
turning off each output on every other clock period of the oscillator. In addition Output A and Output B will never turn
on during the same clock cycle, see Figure 7A below. This would lend itself to a two phase switching system that would
be 180° out of phase..
