SN74AHC08DRG4

Overview

The SN74AHC08DRG4 is a Texas Instruments logic gate featuring four independent 2-input AND gates in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 5.5 V, supporting CMOS logic levels with low static current consumption of 2 µA maximum. The device provides symmetric output drive capabilities of 8 mA for both high and low states. Propagation delay is specified at 7.9 ns when operating at 5 V with a 50 pF load. It functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Contains four independent 2-input AND logic functions
• Supports wide 2 V to 5.5 V supply voltage operation
• Provides 8 mA symmetrical high and low output drive currents
• Operates reliably across extended -40°C to +125°C temperature range

Applications

• General-purpose digital logic processing
• Portable battery-powered equipment due to low power consumption
• Automotive electronics requiring extended temperature stability
• Industrial control systems utilizing CMOS interfaces

Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green manufacturing status. Ensure the DRG4 designation matches the required SOIC-14 surface mount package type. Confirm the AHC series specification aligns with system voltage requirements before procurement. Cross-reference datasheet revisions to ensure compatibility with existing design parameters.

Selection Notes

Select this component for applications requiring standard 5 V or lower voltage logic interfacing with robust drive strength. The AHC series offers faster switching speeds compared to legacy LS or ALS families while maintaining CMOS low power characteristics. Verify that the 8 mA output current meets the capacitive loading requirements of the connected loads. Consider the extended temperature rating for environments exceeding standard commercial limits.

Part Context

This device belongs to the SN74AHC08 family of single-function gates manufactured by Texas Instruments. It serves as a modern replacement for older bipolar logic families like 74LS08, offering improved speed and power efficiency. The component integrates four AND gates into a compact 14-pin small-outline integrated circuit (SOIC) format suitable for space-constrained printed circuit board designs.

Replacement Considerations

The SN74AHC08DRE4 is a verified equivalent variant within the same product line. Both parts share identical logical functionality and electrical specifications. The primary distinction lies in the packaging configuration and specific manufacturing lot details rather than performance characteristics.
