The MC74F194 is a high-speed 4-bit bidirectional universal shift register. As a high-speed multifunctional, sequential building 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 S195 universal shift register, with added features of shift left without external connections and hold (do nothing) modes of operation.

• Typical Shift Frequency of 150 MHz
• Asynchronous Master Reset
• Hold (Do Nothing) Mode
• Fully Synchronous Serial or Parallel Data Transfers
