    December 1992 CMOS 8-Stage Static Shift Registers Features Description High Voltage Types (20V Rating) CD4014BMS -Synchronous Parallel or Serial Input/Serial Output Medium Speed Operation 12MHz (Typ.) Clock Rate at
    VDD-VSS = 10V CD4021BMS -Asynchronous Parallel Input or Synchronous
    Serial Input/Serial Output Fully Static Operation 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 8stage 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. 8 Master-Slave Flip-Flops Plus Output Buffering and
