To allow for bit errors to fade out and to allow ( re ) synchronization to an ongoing bitstream, the output register ( which keeps the reference sample ) is normally realized as a leaky integrator with a time constant ( \ tau ) of about 1 ms.

In cases where the parallel outputs should not change during the serial loading process, it is desirable to use a latched or 74595 ) the serial data is first loaded into an internal buffer register, then upon receipt of a load signal the state of the buffer register is copied into a set of output registers.

A link register is used in many instruction set architectures, such as the PowerPC, ARM, RISC-V and the PA-RISC . Other architectures ( such as SPARC ) have a register with the same purpose but another name ( in this case, " output register 7 " or " o7 " ).
