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.

2. Maximum Ratings are those values beyond which damage to the device
may occur.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high–impedance circuit. For proper operation, 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.
