General Description
The CD40174B consistsofsix positive-edge triggered
D-type flip-flops;thetrue outputs from each flip-flopareex-
ternally available.The CD40175B consistsof four positive-
edge triggered D-type flip-flops; boththetrue and comple-
ment outputs from each flip-flopare externally available.
All flip-flopsare controlledbya common clockanda com-
mon clear. InformationattheD inputs meetingthe set-up
time requirementsis transferredtotheQ outputsonthe
positive-going edgeofthe clock pulse.The clearing opera-
tion, enabledbya negative pulseat Clear input, clearsallQ
outputs tological ‘‘0’’andQs(CD40175Bonly) tological‘‘1’’.
All inputsare protected from static dischargeby diode
clampsto VDDand VSS.
