93L00
4-Bit Universal Shift Register
93L00 4-Bit Universal Shift Register
June 1989
General Description
The 93L00 is a 4-bit universal shift register. As a high speed
multifunctional sequential logic block, it is useful in a wide
variety of register and counter applications. It may be used
in serial-serial, shift left, shift right, serial-parallel, parallelserial, and parallel-parallel data register transfers.

The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
