74LS395PC

Overview

The SN74LS395PC is a Low-Power Schottky (LS) TTL parallel-in/parallel-out shift register manufactured by National Semiconductor. It features four-bit data storage with true outputs and supports right-direction serial shifting. The device operates on a 5 V supply and utilizes a 16-pin plastic DIP package. Key control inputs include clock, mode select for parallel or serial loading, and clear functions.

Feature Summary

• Supports both parallel data loading and serial right-shift operations via dedicated mode control inputs
• Provides true logic outputs compatible with standard TTL interfacing requirements
• Integrates a direct clear function to reset all stored bits simultaneously

Applications

• Data buffering in digital communication systems
• Serial-to-parallel conversion for microprocessor interfaces
• General-purpose shift register applications in LS-TTL circuits

Procurement Notes

Verify the manufacturer origin as National Semiconductor or its successor entities like Texas Instruments. Confirm the package type matches the specified 16-pin DIP configuration. Ensure the component meets the required LS-TTL electrical standards for voltage levels and current drive capabilities before integration into designs.

Selection Notes

Select this component when a compact solution for four-bit data storage and shifting is required within a Low-Power Schottky logic family. It is suitable for designs needing simultaneous parallel access and serial shifting capabilities without requiring external latch components.

Part Context

This part belongs to the widely adopted 74LS series of integrated circuits, known for balancing speed and power consumption in digital logic design. As a shift register variant, it complements other 74LS devices such as counters and decoders in complex sequential logic architectures.
