Dynamic drive capability is equivalent to standard outputs with IOH and IOL of ±24 mA at 2.5-V VCC. See Figure 1 for VOL vs IOL and VOH vs IOH
characteristics. Refer to the TI application reports, AVC Logic Family Technology and Applications, literature number SCEA006, and
Dynamic Output Control (DOC
) Circuitry Technology and Applications, literature number SCEA009.
NOTE 4: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report,
Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
