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.

This quadruple bus buffer 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 SN74AVC126 features independent line drivers with 3-state outputs. Each output is disabled when the  
associated output-enable (OE) input is low.  
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a  
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.  
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 SN74AVC126 is characterized for operation from –40°C to 85°C.
