74AHCT00BQ,115

Overview

The Nexperia 74AHCT00BQ,115 is a quad 2-input NAND gate in the 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device incorporates Schmitt-trigger action on all inputs for improved noise immunity and includes overvoltage tolerant inputs up to 5.5 V. Packaged in a DHVQFN14 (SOT762-1) format with dimensions of 2.5 mm x 3 mm x 0.85 mm, it supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• TTL-compatible input levels ensure direct interfacing with standard digital logic systems.
• Schmitt-trigger action at all inputs provides tolerance for slower signal rise and fall times.
• Overvoltage tolerant inputs allow safe operation in mixed voltage environments without external protection.

Applications

• Signal translation between different logic families
• Digital logic circuit design
• Mixed voltage system integration

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the DHVQFN14 package. Confirm that the selected component meets the required thermal and electrical standards for the intended application environment before finalizing procurement.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS performance characteristics. The DHVQFN14 package offers a compact solution for space-constrained designs. Consider the operating temperature range and power dissipation limits relative to the expected load conditions and ambient environment during system planning.

Part Context

This part belongs to the 74AHCT series, which combines the high-speed performance of Advanced High-CMOS technology with TTL-compatible input levels. The 'BQ' designation specifically identifies the DHVQFN14 package variant. This series is designed for applications requiring robust noise immunity and reliable operation across a wide temperature range.

Replacement Considerations

Direct replacements must match the 74AHCT logic family and DHVQFN14 package. Verify pinout compatibility and electrical specifications such as supply voltage range and propagation delay. Cross-reference with Nexperia's official substitution guide for equivalent parts.
