DESCRIPTION
The 74AVC16834A is a 18-bit universal bus driver. Data flow is controlled by output enable (OE), latch enable (LE) and clock inputs (CP). This product is designed to have an extremely fast propagation delay and a minimum amount of power consumption. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor (Live Insertion). A Dynamic Controlled Output (DCO) circuitry is implemented to support termination line drive during transient. See the graphs on page 9 for typical curves.

Figure 2. Output voltage (VOH) vs. output current (IOH) A Dynamic Controlled Output (DCO) circuit is designed in. During the transition, it initially lowers the output impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figures 1 and 2 show 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 DCO circuit provides a maximum dynamic drive that is equivalent to a high drive standard output device.
