NXP Semiconductors 74LVC04ADB,118

Overview

74LVC04ADB,118 from Nexperia is a hex inverter logic IC with Schmitt-trigger inputs, operating from 1.2 V to 3.6 V supply, supporting mixed-voltage translation between 3.3 V and 5 V systems, and rated for -40 °C to +125 °C ambient temperature - used in level-shifting interfaces and noise-immune digital signal conditioning.

For engineers reviewing the 74LVC04ADB,118 datasheet, 74LVC04ADB,118 pinout, 74LVC04ADB,118 application, or 74LVC04ADB,118 equivalent, key selection concerns include input overvoltage tolerance (5.5 V), propagation delay (≤6.0 ns at 3.3 V), output drive capability (±24 mA), thermal performance in SO14 package, and JEDEC-compliant voltage-level interoperability.

Technical Context

This device implements six independent CMOS inverters with Schmitt-trigger inputs, enabling robust operation with slow-rising or noisy signals. Each gate provides rail-to-rail output swing and exhibits hysteresis of typically 0.3 V at VCC = 3.3 V.

It supports dual-supply translation via 5.5 V-tolerant inputs while powered from as low as 1.2 V, satisfying JESD8-7A, JESD8-5A, and JESD8-C/JESD36 standards. Dynamic power dissipation is governed by CPD = 9.9 pF at VCC = 3.3 V.

FAQ

Can 74LVC04ADB,118 operate with a 1.2 V supply while accepting 5 V inputs?

Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, allowing safe operation at 1.2 V supply while interfacing with 5 V signal sources. Input clamp diodes and internal protection circuitry prevent damage, and logic thresholds scale correctly per JEDEC standards.

What is the maximum output current per inverter at 3.3 V supply?

Each output delivers ±24 mA at VCC = 3.0 V under DC conditions, as specified in Table 6. At 3.3 V, the guaranteed minimum HIGH-level output voltage is 2.2 V (IO = −24 mA), and LOW-level output voltage is 0.55 V (IO = +24 mA), confirming robust drive capability for fan-out and capacitive loads.

Does this part support hot-swap or live-insertion?

No. The 74LVC04ADB,118 lacks explicit hot-swap or Ioff protection features. Its inputs are overvoltage-tolerant but not powered-off isolated; applying signals while VCC = 0 V may cause latch-up or excessive ICC due to internal parasitic paths. Power sequencing must ensure VCC is stable before signal application.

How does Schmitt-trigger action improve noise immunity?

Schmitt-trigger inputs provide hysteresis - typically ~0.3 V at 3.3 V - meaning the rising threshold (VIH) and falling threshold (VIL) differ significantly. This prevents multiple transitions during slow or noisy edges, eliminating glitches caused by ringing, crosstalk, or EMI on long traces or unshielded cables in industrial environments.
