DESCRIPTION

The 74ALVCH16374 is a low voltage CMOS 16 BIT D-TYPEFLIP-FLOP with3 STATEOUTPUTS NON INVERTING fabricated with sub-micron silicon gate and five-layer metal wiring C

2

MOS technology. It is ideal for low power and very high speed 1.65 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. These 16 bit D-TYPE flip-flops are controlled by two clock inputs (nCK ) and two output enable inputs (nOE

). Onthepositivetransitionofthe(nCK),thenQ outputs will be set to the logic stat e that were setup at the nD inputs. While the (nOE

) in put is low, the outputs (nQ) will be in a normal state (HIGH or LOW logic level) and while high level the outputs will be in a high impedance sta te. Any output control does not affect the internal operation of flip flops; that is, the old data can be ret ained or the new data can be entered even while the outputs are off. All inputs and outputs are equipped with protection circuits aga inst static discharge, giving them 2KV ESD immunity and transient exc ess voltage.
