Description

The SN74LS95N is a 4-Bit Parallel-Access Shift Register manufactured by Texas Instruments, housed in a standard 14-pin DIP through-hole package. It supports both serial and parallel synchronous operating modes, with the serial shift-right and parallel-load functions activated by separate clock inputs that are selected via a mode control input.

This flexibility makes the SN74LS95N a versatile building block for data storage, serial-to-parallel or parallel-to-serial conversion, and general shift-register applications in digital logic circuits. Beyond parallel load and serial shifting, the chip also supports a hold mode that maintains the current register state without altering the stored data, which is useful for pausing data movement mid-operation without losing the current values.

Its dual clock/mode-select architecture makes it straightforward to integrate into counters, data buffering circuits, and communication interfacing where controlled bit-shifting is required.
