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.

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. 2002 Sep 11 9 Philips Semiconductors Product data 18-bit registered driver with inverted register enable and Dynamic Controlled Outputs™ (3-State) 74AVC16834A TSSOP56: plastic thin shrink small outline package; 56 leads; body width 6.1 mm SOT364-1 2002 Sep 11 10 Philips Semiconductors Product data 18-bit registered driver with inverted register enable and Dynamic Controlled Outputs™ (3-State) 74AVC16834A TSSOP56: plastic thin shrink small outline package; 56 leads; body width 4.4 mm SOT481-2 2002 Sep 11 11 Philips Semiconductors Product data 18-bit registered driver with inverted register enable and Dynamic Controlled Outputs™ (3-State) 74AVC16834A REVISION HISTORY Rev Date _4 _5 2000 Jul 25 2002 Sep 11 Description Product specification (9397 750 07353); fourth version.
