DESCRIPTION
The HEF4031B is an edge-triggered 64-stage static shift
register with two serial data inputs (D
input A/B, a clock input (CP), a buffered clock output (CO),
and buffered outputs from the 64th bit position (O

the register is shifted one position to the right on the LOW

by a HIGH on A/B. Registers can be cascaded either by
connecting all CP inputs together or by driving CP of the
most right-hand register with the system clock and
connecting CO to CP of the preceding register. When the
second technique is used in the recirculating mode, a
flip-flop must be used to store O
register until the most left-hand register is clocked.
