SN74F08DRE4

Overview

The SN74F08DRE4 is a quadruple 2-input positive-AND gate from the Texas Instruments 74F series, housed in a 14-SOIC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range of 0°C to +70°C. Key electrical characteristics include a low-level output current of 20 mA, a high-level output current of -1 mA, and a maximum propagation delay of 6.6 ns.

Feature Summary

• Contains four independent 2-input AND logic gates
• Provides high-speed switching performance with low propagation delay
• Delivers strong low-level output drive capability

Applications

• Digital logic circuits requiring fast AND operations
• Data acquisition systems
• Telecommunications equipment
• Instrumentation control logic

Procurement Notes

Verify that the ordering suffix 'E4' corresponds to lead-free construction and RoHS compliance as specified by Texas Instruments. Confirm the package type remains 14-SOIC and check for any specific environmental or export classification requirements such as MSL ratings before finalizing procurement documentation.

Selection Notes

Select this component when high-speed logic processing is required within standard 5V logic levels. The 74F series offers faster performance than LS variants but consumes more power. Ensure the application environment stays within the 0°C to +70°C operating temperature range and that the 20 mA sink current meets load requirements.

Part Context

This device belongs to the Texas Instruments 74F (FAST) logic family, designed for applications demanding higher speed than standard TTL. The 'E4' suffix typically indicates lead-free packaging compliant with RoHS standards. It serves as a direct pin-compatible replacement for other 74F08 variants in existing designs requiring updated environmental compliance.
