74LS194 4-bit Bi-directional Shift Register

74LS194 4-Bit Bi-directional Shift Register IC

The 74LS194 is a high-performance 4-bit bi-directional universal shift register. This versatile integrated circuit offers four distinct operating modes: parallel load, shift right, shift left, and inhibit clock. Designed with system designers in mind, it provides both parallel inputs and outputs for flexible data handling. Its synchronous operation ensures precise data manipulation with positive edge-triggered clocking. Capable of speeds up to 25MHz, the 74LS194 is built with standard TTL switching voltages. It features dedicated serial inputs for both left and right shifting operations. A direct overriding clear line is also included for easy reset functionality. This robust IC is an essential component for various digital logic and data processing applications.
