SN74F08DR

Overview

The SN74F08DR is a quadruple 2-input positive-AND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74F logic series and utilizes a 14-SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters 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. It supports a minimum operating temperature of 0°C and a maximum of +70°C.

Feature Summary

• Contains four independent 2-input AND logic gates within a single package
• Utilizes Schottky-clamped transistor technology for high-speed switching performance
• Designed for standard 5 V digital logic applications with defined noise margins

Applications

• Digital signal processing circuits requiring logical conjunction operations

Procurement Notes

Verify the specific suffix 'D' confirms the SOIC-14 package type and tape-and-reel shipping configuration. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering part number aligns exactly with the required logic family specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed logic performance is required compared to standard 74-series alternatives. The 74F series offers faster propagation delays suitable for timing-critical designs. Verify that the 14-pin SOIC footprint fits the target PCB layout constraints and thermal requirements.

Part Context

This device is part of the broader 74F (Fast) logic family produced by Texas Instruments. It shares functional similarities with other quad 2-input AND gates but distinguishes itself through superior speed characteristics derived from its specific semiconductor construction. It serves as a fundamental building block for complex combinational logic networks.

Replacement Considerations

SN74F08D is a verified parameter-equivalent alternative offering identical functionality in a different packaging format.
