Overview
The SN7400DR is a quadruple 2-input NAND gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features four independent logic channels in a 14-SOIC surface-mount package. The device supports low-level output currents up to 16mA and high-level output currents of 400µA, with a maximum propagation delay of 22ns at 5V with 15pF load. It functions reliably across an operating temperature range of 0°C to 70°C.
Feature Summary
- Contains four independent 2-input NAND gates for complex logic implementation
- Provides standard TTL-compatible input and output voltage levels
- Supports surface-mount assembly via 14-pin SOIC packaging
Applications
- General-purpose digital logic circuits
- Signal gating and switching applications
- Microprocessor system interface logic
Procurement Notes
Verify the specific suffix 'D' confirms the SOIC-14 package type and tape-and-reel shipping format. Confirm RoHS compliance status and ensure the manufacturer designation matches Texas Instruments specifications. Validate that the component meets the required industrial temperature range and electrical characteristics before integration into final designs.
Selection Notes
Select this component when standard quad NAND functionality is required in a compact surface-mount form factor. Ensure the design environment supports the specified 5V logic family requirements. Consider thermal management capabilities if multiple gates are utilized simultaneously within the operational temperature limits defined by the datasheet.
Part Context
This part belongs to the SN7400 series of quadruple 2-input positive-NAND gates. It represents a standard bipolar logic solution widely used in digital electronics. The DR suffix specifically denotes the plastic small-outline package variant suitable for automated surface-mount manufacturing processes.
Replacement Considerations
Compatible substitutes include SN7400N (PDIP package) and SN7400D (tube packaging). Cross-reference pinouts and electrical parameters to ensure functional equivalence during replacement or sourcing adjustments.
