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

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 SN74AVC16373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus  
drivers, and working registers. This device can be used as two 8-bit latches or one 16-bit latch. When the  
latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs  
are latched at the levels set up at the D inputs.
