描述:
The 74ALVT162821 is a 20-bit positive-edge triggered D-type flip-flop with 30 Ω termination resistors and 3-state outputs
The device can be used as two 10-bit flip-flops or one 20-bit flip-flop. The device features two clocks (1CP and 2CP) and two output enables (1OE and 2OE), each controlling 10-bits. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (nCP) transition. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Operation of the nOE input does not affect the state of the flip-flops. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs
