DA is selected by a LOW, and DB 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 O63 of the most right-hand register until the most left-hand register is clocked. DESCRIPTION The HEF4031B is an edge-triggered 64-stage static shift register with two serial data inputs (DA, DB), a data select input A/B, a clock input (CP), a buffered clock output (CO), and buffered outputs from the 64th bit position (O63, O63). The output O63 is capable of driving one TTL load. Data from DA or DB, as determined by the state of A/B, is shifted into the first shift register position and all the data in Fig.1 Functional diagram.
