DESCRIPTION

The M54/74HC374, M54/74HC534, arehigh speed

CMOSOCTAL D-TYPEFLIPFLOPWITH3-STATE

OUTPUTS fabricated with in silicon gate C2MOS

technology. They have the same high speed per-

formance of LSTTLcombined with true CMOS low

power comsuption. These8-bit D-type flip-flops are

controlled by aclockinput(CK) and anouputenable

input(OE).On thepositivetransition oftheclock,the

Qoutputswillbesettothelogicstatethatweresetup

at the D inputs (HC374) or their complements

(HC534).

While the OE input is low, the eight outputs will be

in a normal logic state (high or low logic level), and

whilehigh level, the outputs willbe in a high imped-

ance state.The outputcontrol does notaffect thein-

ternaloperation offlip-flops.That is, theolddatacan

be retained or the new data can be entered even

while the outputs are off. The application engineer

has a choice of combination of inverting andnon-in-

vertingoutputs. The HC374and HC574 are identi-

cal, apart from pin layout. The 3-state output

configuration and the wide choice of outline make

bus-organized systems simple. All inputs are

equipped with protection circuits against static dis-

chargeand transient excess voltage.

(*) CPD isdefined as thevalue of the IC’sinternal equivalent capacitance which is calculated from the operating current consumption without load.

(Refer toTest Circuit).Average operting current can beobtained by the followingequation. ICC(opr)= CPD •VCC •fIN +I
