54F 74F194
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
Features
Y Typical shift frequency of 150 MHz
Y Asynchronous master reset
Y Hold (do nothing) mode
Y Fully synchronous serial or parallel data transfers
