The PI74AVC+ 16821is a 20-bit bus interface flip-flop designed for 1.65V to 3.6V VCC operation. It 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...
