54F 74F194
4-Bit Bidirectional Universal Shift Register
General Description
The 鈥橣194 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 鈥橣194 is similar in operation to the 鈥橣195 universal shift
register with added features of shift left without external
connections and hold (do nothing) modes of operation
