Nexperia USA Inc. 74LVCU04AD-Q100J

Overview

74LVCU04AD-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified hex unbuffered inverter in SO14 (SOT108-1) package, operating from 1.2 V to 3.6 V supply with 5.5 V-tolerant inputs. It delivers sub-5 ns propagation delay at 3.3 V and supports mixed-voltage level translation between 3.3 V and 5 V logic domains in automotive body control modules and infotainment interfaces.

For engineers reviewing the 74LVCU04AD-Q100 datasheet, 74LVCU04AD-Q100 pinout, 74LVCU04AD-Q100 application, or 74LVCU04AD-Q100 equivalent, key selection criteria include its unbuffered inverter architecture, -40 °C to +125 °C automotive temperature range, 5.5 V input tolerance, and SO14 package compatibility with AOI-enabled solder joint inspection.

Technical Context

This device implements six independent CMOS unbuffered inverters-each with no internal buffering stage-enabling direct use as linear amplifiers, crystal oscillator gain elements, or astable multivibrator stages. Its input structure accepts voltages up to 5.5 V while powered from as low as 1.2 V, enabling bidirectional voltage-level translation without external biasing.

The unbuffered design yields low propagation delay (typ. 2.0 ns at VCC = 3.3 V), tight output skew (<1.0 ns), and high input impedance (>10⁹ Ω), making it suitable for precision timing circuits and low-jitter clock generation where gate delay matching and minimal signal inversion latency are critical.

FAQ

Can 74LVCU04AD-Q100 operate reliably at 1.2 V supply?

Yes. The device is fully specified down to 1.2 V supply across -40 °C to +125 °C, with guaranteed VOL ≤ 0.12 V and VOH ≥ VCC − 0.5 V at IO = ±100 μA. Propagation delay increases to 6.0 ns at 1.2 V, but functionality remains intact for low-speed wake-up logic and battery-monitoring interfaces.

Is this part suitable for crystal oscillator circuits?

Yes. The unbuffered inverter architecture and low input capacitance (5.5 pF) make it ideal for Pierce oscillator configurations. Application note Fig. 9 specifies R1 = 1–10 MΩ and C1/C2 = 47 pF/22 pF for stable 1–20 MHz oscillation with typical ICC ≈ 2 mA at 3 V.

What is the significance of Side-Wettable Flanks in SO14?

Side-wettable flanks expose solderable metal on the vertical edges of SO14 leads, enabling automated optical inspection (AOI) systems to verify solder joint formation and fillet geometry-critical for zero-defect automotive PCB assembly and IPC-A-610 Class 3 compliance.

How does input clamping work with 5.5 V inputs at 1.2 V VCC?

Internal diodes clamp inputs above VCC + 0.5 V or below GND − 0.5 V. At 1.2 V supply, 5.5 V inputs draw ≤50 mA clamping current (per Table 4), which is safe if sustained for <1 ms and limited by series resistance (≥1 kΩ recommended per input per Nexperia application guidance).
