4-Bit Right-Shift Left-Shift Register
General Description
This 4-bit shift register is a monolithic complementary MOS
(CMOS) integrated circuit composed of four D flip-flops.
This register will perform right-shift or left-shift operations
dependent upon the logical input level to the mode control.
A number of these registers may be connected in series to
form an N-bit right-shift or left-shift register.
When a logical ‘‘0’’ level is applied to the mode control in-
put, the output of each flip-flop is coupled to the D input of
the succeeding flip flop. Right-shift operation is performed
by clocking at the clock 1 input, and serial data entered at
the serial input, clock 2 and parallel inputs A through D are
inhibited. With a logical ‘‘1’’ level applied to the mode con-
trol, outputs to succeeding stages are decoupled and paral-
lel loading is possible, or with external interconnection, shift-
left operation can be accomplished by connecting the out-
put of each flip-flop to the parallel input of the previous
flip-flop and serial data is entered at input D.
