SN74ALVCH16721 具有三态输出的 3.3V 20 位触发器
This 20-bit flip-flop is designed specifically for 1.65-V to 3.6-V VCC operation.
The 20 flip-flops of the SN74ALVCH16721 are edge-triggered D-type flip-flops with qualified clock storage. On the positive transition of the clock (CLK) input, the device provides true data at the Q outputs if the clock-enable (CLKEN)\ input is low. If CLKEN\ is high, no data is stored.
A buffered output-enable (OE)\ input places the 20 outputs in either a normal logic state (high or low) or the 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 lines without need for interface or pullup components
