1−to−64 Bit Variable Length

Shift Register

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.

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.
