Product data sheet

1. General description

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 IOFF. The IOFF circuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.
