4035 CMOS 4位并入、并出移位寄存器

The CD4035B 4-bit parallel-in/parallel-out shift register is a
monolithic complementary MOS (CMOS) integrated circuit
constructed with P- and N-channel enhancement mode
transistors. This shift register is a 4-stage clocked serial register
having provisions for synchronous parallel inputs to
each stage and serial inputs to the first stage via JK logic.
Register stages 2, 3, and 4 are coupled in a serial ``D'' flipflop
configuration when the register is in the serial mode
(parallel/serial control low).
Parallel entry via the ``D'' line of each register stage is permitted
only when the parallel/serial control is ``high''.
In the parallel or serial mode, information is transferred on
positive clock transitions.
When the true/complement control is ``high'', the true contents
of the register are available at the output terminals.
When the true/complement control is ``low'', the outputs are
the complements of the data in the register. The true/complement
control functions asynchronously with respect to
the clock signal.

JK input logic is provided on the first stage serial input to
minimize logic requirements particularly in counting and sequence-
generation applications. With JK inputs connected
together, the first stage becomes a ``D'' flip-flop. An asynchronous
common reset is also provided.
