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 SN74AVCH245 is designed for asynchronous communication between data buses. The device transmits  
data 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 the buses are  
effectively isolated.  
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.

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
