●4-BIT BIDIRECTIONAL

●UNIVERSAL SHIFT REGISTER

●The SN54 /74LS194A is a High Speed 4-Bit Bidirectional Universal Shift Register.As a high speed multifunctional sequential building block, it is useful ina wide variety of applications. It may be used in serial-serial, shift left, shift right,serial-parallel, parallel-serial, and parallel-parallel data register trans fers.The LS194A is similar in operation to theLS195A Universal Shift Register,with added features of shift left without external connections and hold(do nothing) modes of operation. It utilizes the Schottky diode clamped processto achieve highspeeds and is fully compatible with all Motorola TTL families.
