Description
CD4014BMS -Synchronous Parallel or Serial Input/Serial Output
CD4021BMS -Asynchronous Parallel Input or Synchronous Serial
Input/Serial Output CD4014BMS and CD4021BMS series types are
8-stage parallel- or serial-input/serial output registers having
common CLOCK and PARALLEL/SERIAL CONTROL inputs, a single SERIAL
data input, and individual parallel “JAM” inputs to each register
stage. Each register stage is a D-type, master-slave flip-flop. In
addition to an output from stage 8, “Q” outputs are also available
from stages 6 and 7. Parallel as well as serial entry is made into
the register synchronously with the positive clock line transition
in the CD4014BMS. In the CD4021BMS serial entry is synchronous with
the clock but parallel entry is asynchronous. In both types, entry
is controlled by the PARALLEL/SERIAL CONTROL
input. When the PARALLEL/SERIAL CONTROL input is low, data is
serially shifted into the 8-stage register synchronously with the
positive transition of the clock line. When the PARALLEL/
SERIAL CONTROL input is high, data is jammed into the 8-stage
register via the parallel input lines and synchronous with the
positive transition of the clock line. In the CD4021BMS, the CLOCK
input of the internal stage is “forced” when asynchronous parallel
entry is made. Register expansion using multiple packages is
permitted. The CD4014BMS and CD4021BMS are supplied in these 16
lead outline packages:
