SN74LS194A - 4-BIT BIDIRECTIONAL UNIVERSAL SHIFT REGISTER

Description

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 Motorola LS195A Universal Shift Register when used in serial or parallel data register transfers.

Features

  • 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 Motorola 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.

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 right, serial-parallel, parallel-serial, and parallel-parallel data register transfers. The LS194A is similar in operation to the LS195A 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 process to achieve high speeds and is fully compatible with all Motorola TTL families.
