HEF4557B Datasheet (nexperia) - 1-to-64 bit variable length shift register

HEF4557B, 1-to-64 bit variable length shift register

The HEF4557B is a static clocked serial shift register whose length may be programmed to be any number of bits between 1 and 64.

The number of bits selected is equal to the sum of the subscripts of the enabled length control inputs (L1, L2, L4, L8, L16, and L32) plus one.
