74LS194 DIP-16 4-Bit Bidirectional Universal Shift Register IC (TTL, 5V)

Description -

The 74LS194 DIP is a TTL logic integrated circuit that functions as a 4-bit bidirectional universal shift register in a 16-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for serial and parallel data transfer, data storage, and digital signal processing.

The device supports four operating modes: Hold, Shift Right, Shift Left, and Parallel Load, selected through two mode control inputs. It also features independent serial inputs for left and right shifting and an asynchronous master reset, making it ideal for communication systems, data conversion, and embedded applications.
