1-to-64 Bit Variable Length
Shift Register
The MC14557B 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. Serial data may be selected from the A or B data inputs with the
A/B select input. This feature is useful for recirculation purposes. A
Clock Enable (CE) input is provided to allow gating of the clock or
negative edge clocking capability.
The device can be effectively used for variable digital delay lines or
simply to implement odd length shift registers.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
1. Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either VSS or VDD). Unused outputs must be left open.
