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 16-bit buffer/driver 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 SN74AVC16244 is designed specifically to improve the performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented receivers and transmitters.
The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and
symmetrical active-low output-enable (OE) inputs.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
