4-Bit Bidirectional Universal Shift Register

General Description

The ’F194 is a high-speed 4-bit bidirectional universal shift

register As a high-speed multifunctional sequential build-

ing block it is useful in a wide variety of applications It may

be used in serial-serial shift left shift right serial-parallel

parallel-serial and parallel-parallel data register transfers

The ’F194 is similar in operation to the ’F195 universal shift

register with added features of shift left without external

connections and hold (do nothing) modes of operation
