The Logic Diagram and Truth Table indicate the functional characteristics of the LS194A 4-Bit Bidirectional Shift Register.

The LS194A is similar in operation to the ON Semiconductor LS195A Universal Shift Register when used in serial or parallel data register transfers.

of shift left without external connections and hold (do nothing) modes of operation. It utilizes the Schottky diode clamped process to achieve high speeds and is fully compatible with all ON Semiconductor TTL families.
Typical Shift Frequency of 36 MHz.
Asynchronous Master Reset.
Hold (Do Nothing) Mode.
Fully Synchronous Serial or Parallel Data Transfers.
Input Clamp Diodes Limit High Speed Termination Effects.
