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 20-bit noninverting buffer/driver 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 SN74AVC16827 is composed of two 10-bit sections with separate output-enable signals. For either 10-bit  
buffer section, the two output-enable (1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must both be low for the  
corresponding Y outputs to be active. If either output-enable input is high, the outputs of that 10-bit buffer section  
are in the high-impedance state.  
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking 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 SN74AVC16827 is characterized for operation from –40°C to 85°C.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in  
a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.

Eco Plan  
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS  
&
no Sb/Br)  
-
please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.
