25S10PC

Overview

The 25S10PC is a 4-bit shift register manufactured by Rochester Electronics, LLC. It features three-state outputs and operates within the standard commercial temperature range of 0°C to +70°C. The device utilizes a DIP-16 package with ceramic construction. It contains internal circuitry designed for high noise immunity and is characterized for operation over the full military temperature range of -55°C to +125°C in related SN54 series variants, though this specific part is rated for commercial use. Propagation delay is typically 5 ns.

Feature Summary

• Contains four independent shift stages with serial input and parallel output capabilities
• Features three-state outputs for bus-oriented applications
• Constructed with ceramic packaging for durability
• Designed for high noise immunity typical of TTL logic families

Applications

• Data storage and transfer systems
• Parallel-to-serial conversion circuits
• Serial-to-parallel conversion interfaces
• Timing pulse generation

Procurement Notes

Verify the exact package type and pinout configuration against your schematic before integration. Confirm that the commercial temperature rating (0°C to +70°C) meets your operational environment requirements. Ensure compatibility with your system's voltage levels and load conditions. Check for any specific handling instructions regarding the ceramic package. Validate that the manufacturer's testing standards align with your quality assurance protocols.

Selection Notes

Select this component when a 4-bit shift register with three-state outputs is required. Consider it for designs needing ceramic packaging for enhanced reliability. Evaluate its propagation delay characteristics against your system speed requirements. Compare its power consumption and noise immunity against other available logic families. Ensure the DIP-16 form factor fits your board layout constraints.

Part Context

Rochester Electronics specializes in providing lifecycle support for obsolete and hard-to-find semiconductors. This component belongs to the broader family of TTL logic devices, specifically shift registers. The company guarantees performance to original OEM specifications, ensuring compatibility with legacy systems. This part serves as a replacement source for discontinued manufacturers' products.

Replacement Considerations

Direct replacements include SN54S10 or SN74S10 variants if NAND gate functionality is acceptable, though these are functionally different. Verify pin compatibility with SN54LS10 or SN74LS10 if level shifting is involved. Always cross-reference datasheets for electrical parameter equivalence before substitution.
