74AHCU04BQ-Q100X

Overview

The Nexperia 74AHCU04BQ-Q100X is a high-speed Si-gate CMOS hex unbuffered inverter qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, with maximum values of 9.0 ns at 3.6 V/50 pF and 7.0 ns at 5.5 V/50 pF. It utilizes the DHVQFN14 (SOT762-1) package, measuring 2.5 × 3 × 0.85 mm.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards for reliability.
• DHVQFN package design incorporating side-wettable flanks to enable automatic optical inspection of solder joints.
• Input tolerance allows acceptance of voltages exceeding the supply voltage (VCC).
• ESD protection capabilities exceed 2000 V under Human Body Model and 1000 V under Charge Device Model testing.

Applications

• Automotive electronic systems requiring robust logic inversion.
• Crystal oscillator circuit designs utilizing external feedback components.
• Linear amplifier configurations operating within specified gain and bandwidth limits.

Procurement Notes

Verify that the specific ordering suffix matches the required DHVQFN14 package configuration. Confirm the temperature grade aligns with the intended operational environment. Ensure compliance with automotive quality requirements by checking the AEC-Q100 certification status. Validate pinout compatibility against existing schematic designs before finalizing procurement decisions.

Selection Notes

Select this component when space constraints necessitate a leadless thermal enhanced quad flat package. Choose this part for applications requiring inputs tolerant of voltages higher than the local supply rail. Consider this device for designs needing balanced propagation delays across multiple channels. Verify that the low power dissipation characteristics meet the system's thermal management requirements.

Part Context

This device belongs to the 74AHCU04-Q100 family of hex unbuffered inverters manufactured by Nexperia. It serves as a general-purpose logic gate suitable for mixed-signal environments. The product line is designed to be pin-compatible with Low-power Schottky TTL (LSTTL) standards, facilitating direct replacement in legacy designs without PCB layout modifications.

Replacement Considerations

The 74AHCU04PW-Q100 offers identical electrical performance but utilizes a TSSOP14 package. The 74AHCU04D-Q100 provides equivalent functionality within an SO14 plastic small outline package. These alternatives maintain the same AEC-Q100 qualification and logical specifications.
