SN74F08DRG4

Overview

The SN74F08DRG4 is a quadruple 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74F logic series and utilizes BiCMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a low-level output current of 20 mA and a high-level output current of -1 mA. The propagation delay is specified at 6.6 ns. The component is housed in a 14-SOIC package and supports surface-mount installation. It functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND gates for complex logic implementation
• Utilizes BiCMOS technology for high-speed signal processing
• Provides robust drive capability with 20 mA low-level output current

Applications

• Digital logic circuits requiring multiple AND operations
• Data acquisition systems
• Telecommunications equipment
• Computing peripherals

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing options as per Texas Instruments documentation. Confirm the SOIC-14 package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when high-speed logic performance is required within standard 5V logic families. The F series offers faster switching speeds compared to LS or ALS variants. Verify that the 20 mA output drive strength is sufficient for the connected load capacitance. Consider the 14-pin SOIC package constraints during layout design to ensure adequate thermal dissipation and mechanical stability.

Part Context

This part is part of the Texas Instruments 74F series, known for high-speed performance in standard TTL-compatible logic applications. The DRG4 designation specifies the tape-and-reel packaging format and RoHS-compliant construction. It serves as a direct functional replacement for other 74F08 devices in compatible packages, maintaining pinout consistency while offering updated environmental compliance.

Replacement Considerations

SN74F08DR is the non-RoHS equivalent with identical electrical characteristics. SN74ALS08DR offers similar functionality but with lower power consumption and slightly slower speed. SN74LS08DR provides comparable performance with higher noise immunity but significantly slower propagation delays.
