SEMICONDUCTOR TECHNICAL DATA  
L SUFFIX  
CERAMIC  
CASE 620  
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.  
P SUFFIX  
PLASTIC  
CASE 648  
The device can be effectively used for variable digital delay lines or simply  
to implement odd length shift registers.
