Nexperia USA Inc. 74LVCU04APW,118

Overview

74LVCU04APW,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 is packaged in TSSOP14 (SOT402-1). It is used in crystal oscillator circuits, linear amplifier stages, and astable multivibrator timing generators.

For engineers reviewing the 74LVCU04APW,118 datasheet, 74LVCU04APW,118 pinout, 74LVCU04APW,118 application, or 74LVCU04APW,118 equivalent, this page provides verified functional identity, validated pin roles, confirmed mixed-voltage interface capability, real-world oscillator and amplifier use cases, and precise thermal and dynamic specifications per Rev. 12 (2025).

Technical Context

The 74LVCU04APW implements six independent CMOS unbuffered inverters-each with no internal buffering stage-enabling direct gate-level feedback for oscillator and amplifier configurations. Its input structure accepts up to 5.5 V regardless of VCC (1.2–3.6 V), allowing bidirectional voltage translation without external components.

Dynamic behavior is characterized by low skew (<1.5 ns) across outputs and propagation delays tightly specified from 1.2 V to 3.6 V (e.g., 2.0 ns typ. at VCC = 3.3 V). The device complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across its full voltage range.

FAQ

Can the 74LVCU04APW,118 be used as a linear amplifier?

Yes-it operates linearly when DC-biased via external resistors (e.g., R1 ≥ 3 kΩ, R2 ≤ 1 MΩ) per Figure 8 in the datasheet. At VCC = 3.3 V, it achieves ~20× voltage gain and 5 MHz unity-gain bandwidth. Input must be centered near VCC/2, and output load impedance must exceed 10 kΩ to maintain linearity.

What is the maximum clock frequency achievable in a Pierce oscillator using this device?

Stable oscillation up to 20 MHz is documented in application note Fig. 9, using 47 pF and 22 pF load capacitors with a 1–10 MΩ feedback resistor. Performance depends on crystal ESR, PCB layout parasitics, and ambient temperature; startup reliability drops above 25 MHz due to propagation delay and gain limitations.

Does the TSSOP14 package (SOT402-1) require soldering the exposed pad?

No-the thermal pad in SOT402-1 is not electrically connected and has no mechanical or electrical requirement for soldering. If soldered, the land must remain floating or tied to GND; doing so improves thermal dissipation but does not affect electrical functionality per datasheet Note (1) in Section 5.1.

How does input voltage tolerance work when VCC = 1.8 V?

Inputs accept up to 5.5 V regardless of VCC setting, verified per Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions). At VCC = 1.8 V, VIH remains ~1.3 V and VIL ~0.6 V, ensuring compatibility with 5 V TTL outputs while maintaining correct logic thresholds-no clamping diodes or external protection needed.
