Quadruple 64-bit static shift register
DESCRIPTION
The HEF4731B and HEF4731V are quadruple 64-bit static
shift registers each with separate serial data inputs (D
A
to
D
D
), clock inputs (CP
A
to CP
D
) and data outputs (O
63A
to
O
63D
) from the 64th register position.
HEF4731B; HEF4731V
LSI
Recommended supply voltage range for HEF4731B is 3 to
15 V and for HEF4731V is 4,5 to 12,5 V.
Data are shifted to the next stage on the negative-going
transitions of the clock. Low impedance outputs are
provided for direct interface to TTL.

and AC characteristics, are not applicable to the HEF4731V,
because of its reduced supply voltage range.
