SN74LS194A

4-Bit Bidirectional

Universal Shift Register

The SN74LS194A 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 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
