The SN74LS194AN 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.
