SN54/74LS194A 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 in a wide variety of applications. It may be used in serial-serial, shift left, shift 4-BIT BIDIRECTIONAL right, serial-parallel, parallel-serial, and parallel-parallel data register trans- UNIVERSAL SHIFT REGISTER fers. The LS194A is similar in operation to the LS195A Universal Shift Register, with added features of shift left without external connections and LOW POWER SCHOTTKY hold (do nothing) modes of operation. It utilizes the Schottky diode clamped process to achieve high speeds and is fully compatible with all Motorola TTL families.
