3.3-v 20-bit Bus Interface Flip Flops With 3-state Outputs - Hitachi Semiconductor

The HD74ALVCH162821 CAN be used as two 10-bit flip flops or one 20-bit flip flop. The 20 flip flops are edge triggered D-type flip flops. On the positive transition of the Clock (CLK) input, the device provides true data at the Q outputs. A buffered output enable (OE) input CAN be used to place the ten outputs in either a normal Logic state (high or low level) or a high impedance state. In the high impedance state, the outputs neither load nor drive the bus lines significantly. The high impedance state and increased drive provide the capability to drive bus line without need for Interface or pullup components. The output enable (OE) input does not affect the internal operations of the flip flops. Old data CAN be retained or new data CAN be entered while the outputs are in the high impedance state. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid Logic level. All outputs, which are designed to sink up to 12 mA, include 26 resistors to reduce overshoot and undershoot. By Renesas Technology
