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.

The SN74AVC16245 is designed for asynchronous communication between data buses. The control-function  
implementation minimizes external timing requirements.  
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the  
A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR)  
input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
