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 8 for typical curves.

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. 2000 Aug 03 8 Philips Semiconductors Product specification 16-bit registered driver with inverted register enable and Dynamic Controlled Outputs™ (3-State) 74AVC16334A TSSOP48: plastic thin shrink small outline package; 48 leads; body width 6.1mm SOT362-1 2000 Aug 03 9 Philips Semiconductors Product specification 16-bit registered driver with inverted register enable and Dynamic Controlled Outputs™ (3-State) 74AVC16334A Data sheet status Data sheet status Objective specification Preliminary specification Product specification Product status Development Qualification Definition [1] This data sheet contains the design target or goal specifications for product development.
