74LVC16374A; 74LVCH16374A

16-bit edge-triggered D-type flip-flop; 5 V tolerant; 3-state

The 74LVC16374A; 74LVCH16374A is a 16-bit edge-triggered D-type flip-flop with 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. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
