Nexperia USA Inc. 74LVCU04ADB,118

Overview

74LVCU04ADB,118 from Nexperia is a hex unbuffered inverter IC operating from 1.2 V to 3.6 V supply, with 5.5 V-tolerant inputs enabling level translation between 3.3 V and 5 V logic domains. It delivers 2.0 ns typical propagation delay at 3.3 V, supports −40 °C to +125 °C operation, and features 8.4 pF power dissipation capacitance for low dynamic power in clock buffering and oscillator circuits.

For engineers reviewing the 74LVCU04ADB,118 datasheet, 74LVCU04ADB,118 pinout, 74LVCU04ADB,118 application, or 74LVCU04ADB,118 equivalent, key selection criteria include input voltage tolerance (up to 5.5 V), unbuffered inverter architecture for linear amplifier use, SO14 package compatibility, and JEDEC JESD8-7A/5A/C compliance across 1.65–3.6 V rails.

Technical Context

The 74LVCU04ADB,118 implements six independent CMOS unbuffered inverters-each consisting of a single pair of complementary MOSFETs without internal buffering stages-enabling direct use in crystal oscillator feedback loops and linear amplifier configurations. Its input structure accepts voltages up to 5.5 V regardless of VCC, allowing seamless interfacing between mixed-voltage subsystems.

Propagation delay is tightly controlled (0.5–5.0 ns depending on VCC), with output skew limited to 1.5 ns across all six channels at 3.0–3.6 V. The device complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), ensuring interoperability in multi-rail industrial and communications systems.

FAQ

Can the 74LVCU04ADB,118 be used as a linear amplifier?

Yes. When DC-biased with appropriate feedback resistors (e.g., R1 ≥ 3 kΩ, R2 ≤ 1 MΩ), the unbuffered inverter operates in its linear region, delivering ~5 MHz unity-gain bandwidth and 20× typical voltage gain. This configuration is explicitly validated in Nexperia's Application Information section (Fig. 8) and leverages the device's inherent transconductance characteristics.

What is the maximum clock frequency supported in oscillator mode?

The 74LVCU04ADB,118 supports stable oscillation up to 20 MHz in Pierce crystal configurations, as confirmed by Nexperia's application note (Fig. 9). Performance depends on crystal load capacitance (typically 47 pF and 22 pF), supply voltage (optimal at 3.0–3.3 V), and external resistor values (R1 = 1–10 MΩ).

Does the SO14 package (SOT108-1) have thermal pad or exposed die attach?

No. The SO14 (SOT108-1) package for 74LVCU04ADB,118 is a standard plastic small-outline package with gull-wing leads and no thermal pad or exposed copper. Thermal performance relies on PCB copper pour connected to pins 7 (GND) and 14 (VCC), with Ptot derating starting at 100 °C (10.1 mW/K).

Is the 74LVCU04ADB,118 automotive qualified?

No. Although rated for −40 °C to +125 °C operation, the 74LVCU04ADB,118 is not AEC-Q100 qualified and carries no automotive-specific reliability testing or qualification documentation. Nexperia explicitly states in its Legal Information section that non-automotive qualified products are unsuitable for safety-critical or life-support systems.
