Overview
The SN74F08DE4 is a quadruple 2-input positive AND gate from the Texas Instruments 74F logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features a 14-pin SOIC package. The device provides a low-level output current of 20 mA and a high-level output current of -1 mA. Propagation delay is specified at 6.6 ns, with a maximum value of 5.6 ns under specific load conditions. It functions reliably across an operating temperature range of 0°C to +70°C.
Feature Summary
- Contains four independent 2-input AND gates for complex logic implementation
- Utilizes Fast (F) TTL technology for high-speed signal processing
- Provides robust low-level sink current capability for driving loads
Applications
- Digital logic circuit design requiring AND operations
- Data routing and selection systems
- Control logic in industrial automation equipment
Procurement Notes
Verify the exact suffix against manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS standards if required by your assembly process. Cross-reference the ordering part number with official Texas Instruments databases to validate availability and revision status before finalizing procurement plans.
Selection Notes
Select this component when high-speed performance is critical compared to standard or LS series alternatives. The 74F series offers superior propagation delays suitable for timing-sensitive applications. Consider the 14-SOIC package dimensions for PCB layout constraints and ensure thermal management aligns with the specified operating temperature range.
Part Context
This part belongs to the extensive 74-series logic family, specifically the F (Fast) sub-family known for speed optimization. It serves as a fundamental building block in digital electronics, providing reliable Boolean AND functionality. The DE4 suffix indicates a specific manufacturing variant compliant with environmental directives, distinct from standard commercial versions.
Replacement Considerations
SN74F08DR is a verified equivalent offering identical logical function and pin configuration. SN74F08DRE4 is another confirmed substitute within the same product line. Verify that any replacement maintains the same 14-SOIC footprint and electrical characteristics.
