4-Bit Bidirectional Universal Shift Register
General Description
The ’F194isa high-speed 4-bit bidirectional universal shift
register.Asa high-speed, multifunctional, sequential build-
ing block,itis usefulina wide varietyof applications.It may usedin serial-serial, shift left, shift right, serial-parallel,
parallel-serial, and parallel-parallel data register transfers.
The ’F194is similarin operationtothe ’F195 universal shift
register, with added featuresof shiftleft without external
connectionsand hold(do nothing) modesof operation.
Features Typical shift frequencyof150 MHz Asynchronous master reset Hold(do nothing) mode Fully synchronous serialor parallel data transfers
