74178PC

Overview

The 74178PC is a parallel-in, parallel-out shift register manufactured by Rochester Electronics. It belongs to the standard logic family and is housed in a 16-pin DIP package. The component supports serial input for data shifting and provides parallel output access. It operates within a specified voltage range suitable for standard digital logic applications. The device is designed for surface mount or through-hole integration depending on the specific package variant, though the PC suffix typically denotes a plastic DIP configuration. It functions as a basic storage element for sequential logic circuits.

Feature Summary

• Parallel-in parallel-out data shifting capability
• Standard logic family compatibility
• Through-hole packaging option

Applications

• Digital data storage
• Sequential logic circuits
• Parallel-to-serial conversion interfaces

Procurement Notes

Verify the exact manufacturer source, as Rochester Electronics often distributes components sourced from original manufacturers. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for any obsolescence notices or lifecycle changes. Ensure the package type matches the design requirements. Validate part authenticity through authorized channels.

Selection Notes

Select this component for applications requiring simple parallel data storage and shifting. Consider the DIP package for prototyping or through-hole designs. Verify voltage levels match the system logic standards. Evaluate space constraints against the physical dimensions of the package. Ensure compatibility with existing clock and control signals.

Part Context

Rochester Electronics specializes in distributing obsolete and hard-to-find electronic components. They provide lifecycle management solutions for parts no longer produced by original equipment manufacturers. This company serves industries requiring continued availability of legacy semiconductors. Their portfolio includes various logic, memory, and analog devices.

Replacement Considerations

Check for direct pin-compatible substitutes from other manufacturers if available. Verify logical equivalence for shift register functionality. Ensure voltage and current specifications meet or exceed original requirements. Review package dimensions for mechanical fit.
