Overview
The SN74F51N is a dual wide-or-and-invert logic gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 60 ns. The device supports a maximum supply current of 1.3 mA and functions reliably across an operating temperature range from 0 °C to +70 °C. Packaged in a standard 14-pin PDIP format, it provides two independent logic circuits for digital signal processing applications.
Feature Summary
- Integrates two independent AND-OR-Invert (AOI) logic gates within a single package
- Supports asymmetrical input configurations for flexible logic design
- Compatible with standard TTL logic families for direct interfacing
Applications
- Digital logic control systems requiring complex boolean operations
- Microprocessor interface circuits for address decoding
- General-purpose combinational logic implementation
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status before procurement. Confirm that the PDIP-14 package matches your PCB footprint requirements. Ensure the operating environment stays within the specified 0 °C to +70 °C temperature range to maintain guaranteed electrical performance and reliability standards.
Selection Notes
Select this component when designing circuits that require dual AOI functionality without consuming multiple IC footprints. It serves as a suitable alternative to discrete gate combinations, reducing board space and assembly complexity. Consider its 60 ns propagation delay when evaluating timing constraints for high-speed digital signals compared to faster logic families.
Part Context
This part belongs to the Texas Instruments SN74F series, which utilizes advanced fast transistor-transistor logic technology. The SN74F51N specifically addresses applications needing efficient implementation of complex logic expressions. Its PDIP-14 packaging facilitates through-hole mounting for prototyping and industrial equipment where mechanical robustness is prioritized over miniaturization.
Replacement Considerations
Check for SN74LS51N or SN74S51N equivalents if different speed or power characteristics are required. Verify pin compatibility and logical equivalence before substitution to ensure circuit functionality remains unchanged.
