16位缓冲器/驱动器，具有三态输出 16-BIT BUFFER/DRIVER WITH 3-STATE OUTPUTS

DESCRIPON/ORDERING INFORMATION

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.
