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 VOL vs IOL and VOH vs IOH 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.

Figure 1. Output Voltage vs Output Current
This 18-bit universal bus transceiver is operational at 1.2-V to 3.6-V VCC, but is designed specifically for 1.65-V
to 3.6-V VCC operation.
The SN74AVC16601 combines D-type latches and D-type flip-flops to allow data flow in transparent, latched,
and clocked modes.
