74LVC30ABQX

Inverter Gates Overview

The Nexperia 74LVC30ABQX is an 8-input NAND gate from the LVC logic family, housed in a DHVQFN14 package (SOT762-1). It operates on a supply voltage range of 1.2 V to 3.6 V and accepts input voltages up to 5.5 V. The device features Schmitt trigger inputs for noise tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.4 ns at 3.0–3.6 V to 11.6 ns at 1.65–1.95 V. Operating temperature spans -40 °C to +125 °C.

Inverter Gates Feature Summary

• Supports mixed 3.3 V and 5 V environments via overvoltage tolerant inputs
• Includes IOFF circuitry to prevent backflow current during partial power-down
• Schmitt trigger action provides tolerance for slow input rise and fall times

Inverter Gates Applications

• Mixed 3.3 V and 5 V logic translation
• Partial power-down applications requiring output disable
• Systems with slow signal transition rates

Inverter Gates Procurement Notes

Verify the specific suffix 'BQX' against official Nexperia documentation to confirm tape-and-reel packaging details and exact pinout compatibility. Ensure the DHVQFN14 thermal pad soldering requirements are addressed in the PCB layout design. Confirm that the component meets the required ambient temperature specifications for the target application environment.

Inverter Gates Selection Notes

Select this component when an 8-input NAND function is required within low-voltage CMOS systems. The wide supply range supports operation from 1.2 V to 3.6 V. The 5.5 V input tolerance allows direct interfacing with higher voltage logic levels without additional level shifting components.

Inverter Gates Part Context

This part belongs to the 74LVC30A series of 8-input NAND gates manufactured by Nexperia. The standard versions include SO14 and TSSOP14 packages, while the ABQ variant specifically utilizes the leadless DHVQFN14 package for space-constrained surface-mount designs.

Inverter Gates Replacement Considerations

Direct replacements include the 74LVC30AD (SO14) and 74LVC30APW (TSSOP14). Verify pinout compatibility and package dimensions before substituting, as the DHVQFN14 footprint differs from standard plastic outlines.
