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. 1–64 Bit Programmable Length Q and Q Serial Buffered Outputs Asynchronous Master Reset All Inputs Buffered No Limit On Clock Rise and Fall Times Supply Voltage Range = 3.0 Vdc to 18 Vdc Capable of Driving Two Low–power TTL Loads or one Low–power
