74LS194 4 bit Bi directional Shift Register IC (74194) DIP 16 Package

74LS194 4 bit Bi directional Shift Register IC (74194) DIP 16 Package

The 74LS194 is a 4-bit bidirectional universal shift register from the 74LS TTL logic family.
It is designed to store and shift data left or right, or to load data in parallel, depending on the mode control inputs.

This IC combines parallel load, serial shift (left/right), and storage functions in one device.
It is commonly used in data transfer, bit manipulation, and serial communication systems.

The 74LS194 operates synchronously with a single clock input, and all outputs change state simultaneously on the clock’s rising edge.
