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 16-bit (dual octal) noninverting 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 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.
