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 trans-
fers. 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.
• 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
