4031 CMOS 64级静态移位寄存器

The CD4031BM/CD4031BC is an integrated, complementary
MOS (CMOS), 64-stage, fully static shift register. Two
data inputs, DATA IN and RECIRCULATE IN, and a MODE
CONTROL input are provided. Data at the DATA input
(when MODE CONTROL is low) or data at the RECIRCULATE
input (when MODE CONTROL is high), which meets
the setup and hold time requirements, is entered into the
first stage of the register and is shifted one stage at each
positive transition of the CLOCK.
Data output is available in both true and complement forms
from the 64th stage. Both the DATA OUT (Q) AND DATA
OUT (Q) outputs are fully buffered.
The CLOCK input of the CD4031BM/CD4031BC is fully
buffered, and present only a standard input load capacitance.
However, a DELAYED CLOCK OUTPUT (CLD) has
been provided to allow reduced clock drive fan-out and transition
time requirements when cascading packages.
