Overview
The SN74F260N is a dual 5-input positive-NOR gate from the Texas Instruments SN74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 13 ns at 5 V. The device provides high-level output current of -1 mA and low-level output current of 20 mA. It functions in an ambient temperature range of 0°C to +70°C and is housed in a 14-pin PDIP package.
Feature Summary
- Contains two independent 5-input NOR gates for complex logic implementation
- Provides standard TTL-compatible input and output characteristics
- Supports through-hole mounting via a 14-pin DIP package
Applications
- Digital logic circuit design requiring multi-input NOR functionality
- Microprocessor interface circuits
- General-purpose computing systems
Procurement Notes
Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 14-pin DIP configuration. Confirm that the intended application environment falls within the specified operating temperature range of 0°C to +70°C before finalizing component selection.
Selection Notes
Select this component when dual 5-input NOR logic is required within the SN74F family. Consider the 14-pin PDIP package for prototyping or applications requiring through-hole assembly. Verify that the 5V logic level requirements align with the system's power supply and signal integrity standards.
Part Context
This part belongs to the SN74F series, known for high-speed performance compared to standard LS logic. The SN74F260 specifically integrates two separate NOR gates into a single package, offering a compact solution for designs needing multiple high-fan-in logic operations without consuming excessive board space.
Replacement Considerations
Check for direct equivalents such as the SN74LS260 if speed requirements are less critical, or other SN74F variants with similar pinouts. Ensure any substitute maintains the same 5-input NOR function and compatible electrical specifications.
