Overview
The SN72275N is a standard TTL logic gate manufactured by Texas Instruments, specifically designed as a triple 3-input NOR gate. It operates with a nominal supply voltage of 5 V and is housed in a 14-pin plastic dual in-line package (DIP). The device features three independent NOR gates, each accepting three inputs to produce a single output. This component belongs to the standard TTL logic family, providing reliable digital switching for general-purpose logic applications within industrial temperature ranges.
Feature Summary
- Triple 3-input NOR logic functionality
- Standard TTL logic family compatibility
- Plastic dual in-line package construction
Applications
- General-purpose digital logic circuits
- Industrial control systems requiring NOR logic
- Educational electronics prototyping
Procurement Notes
Verify the specific manufacturer source and authenticity when sourcing this component, as it may be an older or legacy part. Confirm the package type matches your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a triple 3-input NOR function is required in a standard DIP package. It is suitable for designs utilizing traditional TTL logic levels. Consider pin compatibility and package dimensions during layout. Evaluate availability as this may be a discontinued or limited-production item compared to modern alternatives.
Part Context
This part belongs to the Texas Instruments SN74xx series of logic integrated circuits. The 'SN' prefix typically denotes commercial grade devices. The '72275' designation identifies the specific logic function as a triple 3-input NOR gate. It represents a classic discrete logic solution before the widespread adoption of complex programmable logic devices.
Replacement Considerations
Compatible replacements include other manufacturers' equivalents such as the MC74LS27 or CD74HC27, provided voltage levels and package types are compatible. Verify that substitute parts meet the same electrical specifications and physical dimensions for direct pin-to-pin replacement.
