This device can be used as two 8-bit Flip-Flops or one 16-bit flipflop. On the positive transition of the clock (CLK) input, the Q outputs of the flip-flop take on the logic levels set up at the date (D) inputs. • Supports Live Insertion • Balanced Drive, ±24mA • Uses patented Noise Reduction Circuitry • Typical VOLP (Output Ground Bounce) A buffered Output Enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state in which the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without need for interface or pullup components. OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while the outputs are in the high impedance state. < 0.6V at VDD = 2.5V, TA = 25ºC • Typical VOHV (Output VOH Undershoot) < –0.6V at VDD = 2.5V, TA = 25ºC • Power-Off high impedance inputs and outputs • Industrial operation at –40°C to +85°C • Packaging (Pb-free & Green available): To ensure the high-impedance state during power up or power down, OE should be tied to VDD through a pullup resistor; the minimum value of the resistor is determined by the currentsinking capability of the driver. – 48-pin 240 mil. wide plastic TSSOP (A) The PI74VCX family is I/O Tolerant, allowing it to operate in mixed 1.8V/3.6V systems.
