74HCT08BQ-Q100,115

Overview

The Nexperia 74HCT08BQ-Q100,115 is a quad 2-input AND gate from the 74HCT08-Q100 logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device utilizes a DHVQFN14 package (SOT762-1) with dimensions of 2.5 × 3 × 0.85 mm. It features TTL-level input compatibility, ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), and latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards for automotive applications.
• TTL-level input compatibility enabling direct interfacing with TTL logic systems.
• DHVQFN package design with side-wettable flanks facilitating automatic optical inspection of solder joints.

Applications

• Automotive electronic circuits requiring robust logic gating.
• Digital signal processing interfaces utilizing TTL-compatible inputs.
• General-purpose logic applications operating at 5 V supply voltages.

Procurement Notes

Verify that the specific ordering suffix matches the required DHVQFN14 package configuration. Confirm compliance with AEC-Q100 Grade 1 requirements if deploying in automotive environments. Ensure thermal management aligns with the specified power dissipation derating curves for the SOT762-1 package variant.

Selection Notes

Select this component when TTL-level input thresholds are necessary within a CMOS logic environment. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Verify that the 4.5 V to 5.5 V supply voltage range meets the system's power distribution specifications.

Part Context

This part belongs to the 74HCT08-Q100 series, which integrates four independent 2-input AND gates. The HCT designation indicates compatibility with standard TTL logic levels, distinguishing it from HC variants that utilize CMOS thresholds. The Q100 suffix denotes automotive-grade qualification, ensuring reliability under extended temperature ranges and rigorous environmental stress testing.

Replacement Considerations

Cross-reference with other 74HCT08-Q100 variants such as the SO14 or TSSOP14 packages if pinout compatibility allows. Verify functional equivalence with other manufacturers' 74HCT08 devices, ensuring supply voltage and input threshold specifications match the original design requirements.
