具有三态输出的16位总线收发器 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS
DESCRIPON
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.
