Seven-segment Iiquiocrystal display digit can be driven directly by CD4054A, CD4055A,or CD4056A CMOS because these circuits contain internal leve-shifting feature needed to convert 5-V input logic swings to 30-V peak AC sigpal required for driving dynamic-scattering LCD，－ COS/MOS Integrated Circuits, RCA Solid State Dlvision,Somerville,NJ,1977,p 629.
