SN74AHC08DBR

Overview

The SN74AHC08DBR is a quad 2-input positive AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features low static power consumption with a maximum quiescent current of 2 µA. The device utilizes a 14-SSOP package and supports surface mount installation. It provides symmetric output drive capabilities of 8 mA for both high and low states. Maximum propagation delay is specified at 7.9 ns when operating at 5 V with a 50 pF load. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Contains four independent 2-input AND logic gates in a single integrated circuit
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Provides symmetric 8 mA output drive capability for reliable signal transmission
• Ensures low static power consumption suitable for battery-powered applications

Applications

• Digital logic circuits requiring multiple AND operations
• Portable electronic devices utilizing low-power CMOS technology
• Industrial control systems operating in extended temperature environments
• Communication equipment interfacing between different voltage domains

Procurement Notes

Verify the specific ordering suffix to confirm the package type matches the design requirements, as variations exist within the product family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant meets all applicable environmental regulations for the target market. Cross-reference the datasheet revision history to validate parameter consistency against previous versions.

Selection Notes

Select this component when a quad AND gate configuration is required within a compact SSOP footprint. The wide supply voltage range allows compatibility with various digital logic families. Consider the 7.9 ns propagation delay for timing constraints in high-speed designs. Verify that the 8 mA drive strength suffices for the connected load capacitance without external buffering.

Part Context

This part belongs to the SN74AHC08 series, which represents high-speed CMOS logic technology. The AHC series offers performance comparable to LS TTL but with lower power consumption and wider voltage operation. The DBR suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

SN74AHC08DR serves as a direct alternative offering identical logical functionality and pinout compatibility.
