description
A Dynamic Output Control (DOC) circuit is implemented, which, during the transition, initially lowers the output
impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1
shows typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the
circuit. At the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is
equivalent to a high-drive standard-output device. For more information, 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.

Figure 1. Output Voltage vs Output Current
This quadruple 2-input positive-OR gate is operational at 1.2-V to 3.6-V VCC, but is designed specifically for
1.65-V to 3.6-V VCC operation.
The SN74AVC86 performs the Boolean function Y = A
⊕ B or Y = AB + AB in positive logic.
A common application is as a true/complement element. If one of the inputs is low, the other input is reproduced
in true form at the output. If one of the inputs is high, the signal on the other input is reproduced inverted at
the output.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The SN74AVC86 is characterized for operation from –40
°C to 85°C.
