NXP Semiconductors 74LVC04APW/AUJ

Overview

74LVC04APW/AUJ from Nexperia is a hex inverter IC with Schmitt-trigger inputs, operating across 1.2 V to 3.6 V supply, tolerant to 5.5 V inputs, and rated for -40 °C to +125 °C. It enables level translation between 3.3 V and 5 V logic domains and delivers sub-6 ns propagation delay at 3.3 V in TSSOP14 packaging. It is used in bus buffering, clock signal conditioning, and noise-immune digital interface circuits.

For engineers reviewing the 74LVC04APW/AUJ datasheet, 74LVC04APW/AUJ pinout, 74LVC04APW/AUJ application, or 74LVC04APW/AUJ equivalent, key selection criteria include input overvoltage tolerance, wide V_CC range (1.2–3.6 V), guaranteed operation up to +125 °C, Schmitt-trigger hysteresis for slow-edge immunity, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The 74LVC04APW/AUJ implements six independent CMOS inverter gates with Schmitt-trigger inputs on a single die, enabling robust signal inversion in mixed-voltage systems. Each gate features symmetrical input thresholds and rail-to-rail output swing, supporting direct TTL-level interfacing without external biasing.

Its design supports dynamic operation up to 200 MHz (based on t_pd ≤ 4.5 ns and t_sk(o) ≤ 1.5 ns at V_CC = 3.0–3.6 V), with input transition rate tolerance up to 10 ns/V and ESD protection exceeding 2000 V HBM and 1000 V CDM - critical for industrial control and portable electronics interfaces.

FAQ

What is the maximum input voltage the 74LVC04APW/AUJ can tolerate?

The 74LVC04APW/AUJ supports input voltages up to 5.5 V regardless of supply voltage (1.2 V to 3.6 V), enabling safe interfacing with 5 V peripherals without external protection. This overvoltage tolerance is explicitly specified in Table 4 (Limiting Values) and Table 5 (Recommended Operating Conditions) of the Nexperia datasheet Rev. 13.

Does the 74LVC04APW/AUJ have Schmitt-trigger inputs, and why does it matter?

Yes, the 74LVC04APW/AUJ features Schmitt-trigger action at all six inputs, providing hysteresis that rejects noise on slow-rising or slow-falling signals. This is critical in applications like mechanical switch debouncing or analog sensor signal conditioning, where it prevents multiple transitions due to signal ringing or EMI - a feature confirmed in Section 1 (General description) and Section 2 (Features and benefits) of the datasheet.

What is the operating temperature range for the 74LVC04APW/AUJ?

The 74LVC04APW/AUJ is fully specified from -40 °C to +125 °C, validated across both static and dynamic parameters per Tables 5–10 in the Nexperia datasheet. This extended industrial temperature grade makes it suitable for under-hood automotive modules, power converters, and outdoor industrial equipment where thermal stress exceeds commercial-grade limits.

Can the 74LVC04APW/AUJ be used as a level shifter between 3.3 V and 5 V logic domains?

Yes - the 74LVC04APW/AUJ is explicitly designed for this role. Its 5.5 V input tolerance allows direct connection to 5 V outputs, while its 1.2–3.6 V V_CC range ensures compatible 3.3 V (or lower) output swing. Section 1 of the datasheet states: "Inputs can be driven from either 3.3 V or 5 V devices… allows use as translators in mixed 3.3 V and 5 V environments."

What package type is used for the 74LVC04APW/AUJ, and what are its key mechanical dimensions?

The 74LVC04APW/AUJ uses the TSSOP14 package (SOT402-1): 14-lead, 0.65 mm lead pitch, 4.4 mm body width, and 1.2 mm max height. These dimensions are defined in Section 3 (Ordering information) and Figure 9 of the Nexperia datasheet Rev. 13, and the package is optimized for high-density surface-mount assembly with thermal performance derating of 7.3 mW/K above 81 °C.
