1. General description

The 74ALVCH16374 is a 16-bit edge-triggered D-type flip-flop with bus hold inputs and 3-state

outputs. The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. The device features

two clocks (1CP and 2CP) and two output enables (1OE and 2OE), each controlling 8-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. This device is fully specified for partial power down applications using IOFF. The IOFF

circuitry disables the output, preventing the potentially damaging backflow current through the

device when it is powered down..
