64-stage static shift register
the register is shifted one position to the right on the LOW
to HIGH transition of CP. 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.
