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

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.

Figure 1. Output Voltage vs Output Current

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.
