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 V vs I and V  
vs I  
curves to illustrate the output impedance and drive capability of the  
OL

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.

operation.  
CC  
Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode  
when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CLK) input is held  
at a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition  
of CLK. When OE is high, the outputs are in the high-impedance state.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
