Dual 64-Bit Static Shift
Register
identical, independent, 64–bit registers. Each register has separate clock
and write enable inputs, as well as outputs at bits 16, 32, 48, and 64. Data
at the data input is entered by clocking, regardless of the state of the write
enable input. An output is disabled (open circuited) when the write enable
input is high. During this time, data appearing at the data input as well as
the 16–bit, 32–bit, and 48–bit taps may be entered into the device by
application of a clock pulse. This feature permits the register to be loaded
with 64 bits in 16 clock periods, and also permits bus logic to be used.
This device is useful in time delay circuits, temporary memory storage
circuits, and other serial shift register applications.
