74HC194 Bidirectional Shift Register

The 74HC194 is a high-speed CMOS 4-bit bidirectional universal shift register in a DIP-16 package. It supports shifting data both left and right, as well as parallel loading, making it versatile for various digital applications. Its four control inputs (S0, S1, CLK, MR) allow mode selection for hold, shift left, shift right, or parallel load operations.

This IC features TTL-compatible inputs and outputs, ensuring easy interfacing with microcontrollers, digital logic circuits, and other 74-series ICs. It is widely used in digital data storage, serial-to-parallel conversion, arithmetic operations, and communication systems.

With low power consumption, fast switching speeds, and robust performance, the 74HC194 is an excellent choice for educational projects, prototyping, and professional circuit designs. Its DIP-16 form factor makes it breadboard-friendly and suitable for integration into custom PCBs.
