74LS95 / 7495 4-bit Parallel-Access Shift Register IC

The 74LS95 (also known as 7495) is a 4-bit parallel-access shift register integrated circuit designed for digital data storage and transfer applications. It contains four flip-flop stages that allow data to be stored and shifted either serially or loaded in parallel, making it a flexible component for various sequential logic operations.

This IC supports both parallel loading of data into the register and serial shifting of data through the stages. This dual-mode operation makes it highly useful in systems where data needs to be temporarily stored, converted between serial and parallel formats, or processed sequentially. It is commonly used in digital communication systems, timing circuits, and data manipulation applications.

The 74LS95 operates using standard Low-Power Schottky TTL technology, providing fast switching speeds and reliable performance. It works with a supply voltage range of 4.75V to 5.25V, making it fully compatible with standard TTL logic systems. With a typical maximum clock frequency of up to 25 MHz and a propagation delay of around 15 ns, it supports high-speed digital operations. The IC is designed to operate within a temperature range of 0°C to 70°C, suitable for commercial and educational electronics applications.
