4-BIT BIDIRECTIONAL

UNIVERSAL SHIFT REGISTER

The SN54/74LS194A is a High Speed 4-Bit Bidirectional Universal Shift

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

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.
