Quadruple 64-bit static shift register
Product specification
HEF4731B; HEF4731V
LSI
Fig.3 Logic diagram (one of 64-bits shift register).
The values given at VDD = 15 V in the following DC
and AC characteristics, are not applicable to the HEF4731V,
because of its reduced supply voltage range.

fi = input freq. (MHz)
fo = output freq. (MHz)
CL = load capacitance (pF)
∑ (foCL) = sum of outputs
VDD = supply voltage (V)
