Product details
Overview
74HC04BZZ from Nexperia is a CMOS hex inverter IC operating across 2.0 V to 6.0 V supply, delivering six independent logic-level inversion stages with propagation delay as low as 7 ns at VCC = 6.0 V and CL = 50 pF, used for signal conditioning, level translation, and clock buffering in industrial control and embedded interface circuits.
For engineers reviewing the 74HC04BZZ datasheet, 74HC04BZZ pinout, 74HC04BZZ application, or 74HC04BZZ equivalent, key selection considerations include its DHXQFN14 package (2 mm × 2 mm × 0.48 mm, 0.4 mm pitch), -40 °C to +125 °C temperature rating, TTL-compatible input thresholds (74HCT variant), and CMOS-level input compatibility (74HC variant).
Technical Context
The 74HC04BZZ implements six independent Schmitt-trigger–free CMOS inverters in a single monolithic die, each with symmetrical input clamping diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Its architecture supports rail-to-rail output swing and exhibits high noise immunity due to typical VIH/VIL margins of 1.5 V and 0.8 V respectively at VCC = 2.0 V.
It operates within JEDEC-compliant voltage standards (JESD7A for 2.0–6.0 V, JESD8C for 2.7–3.6 V) and meets stringent ESD robustness requirements: HBM >2000 V and CDM >1000 V. Latch-up immunity exceeds 100 mA per JESD78 Class II Level B, ensuring reliability in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - Enables direct integration into 3.3 V and 5 V systems without level shifters. |
| Propagation Delay (tpd) | 7 ns (typ) at VCC = 6.0 V, CL = 50 pF - Supports high-speed digital timing up to ~70 MHz toggle rate. |
| Output Drive Strength | ±4.0 mA (VOH/VOL) at VCC = 4.5 V - Sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF). |
| Input Thresholds (74HC) | VIH = 1.5 V min, VIL = 0.5 V max at VCC = 2.0 V - Ensures clean switching with wide noise margin in low-voltage logic domains. |
| Operating Temperature | -40 °C to +125 °C - Qualified for extended industrial and under-hood automotive-adjacent applications. |
| Power Dissipation (Ptot) | 250 mW (SOT8014-1) - Thermal design must account for derating above 95 °C ambient in compact PCB layouts. |
| Input Capacitance (CI) | 3.5 pF - Minimizes loading on preceding stage; critical for high-frequency fanout stability. |
Pinout & Package
DHXQFN14 (SOT8014-1) package: leadless, 2 mm × 2 mm × 0.48 mm body, 0.4 mm pitch, 14 terminals, thermal pad (non-soldered or floating GND connection recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | CMOS/TTL-compatible logic inputs; clamp diodes allow overvoltage tolerance with series resistors. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted logic outputs; rail-to-rail swing with ±4 mA drive capability at VCC = 4.5 V. |
| 7 | GND | Ground reference (0 V); required for all internal biasing and noise return paths. |
| 14 | VCC | Primary power supply; decoupling capacitor (100 nF) strongly recommended adjacent to pin. |
| Thermal Pad (exposed bottom) | Thermal / Mechanical Anchor | No electrical function unless explicitly connected to GND; improves thermal resistance by ~30 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0–6.0 V operation enables interoperability across legacy 5 V and modern 3.3 V/2.5 V logic families. |
| High Noise Immunity | Typical VIH–VIL margin >1.0 V at VCC = 4.5 V ensures reliable operation in electrically noisy factory-floor environments. |
| Input Clamp Diodes | Enable safe interface to signals up to VCC + 0.5 V using external current-limiting resistors-no external protection needed. |
| Low Dynamic Power | CPD = 21 pF (74HC) allows <10 μW static + dynamic power at 1 MHz, 5 V, reducing thermal load in dense layouts. |
| Extended Temp Rating | -40 °C to +125 °C qualification supports use in sealed enclosures or near heat-generating components. |
Applications
| Industrial PLC I/O Conditioning | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Inverting sensor status signals (e.g., limit switch active-low outputs) before feeding into a PLC's 24 V DC input module. IC Role / Device Role / Timing Role: Signal polarity correction and noise filtering via inherent hysteresis-free CMOS threshold stability. Use Value: Eliminates need for discrete transistor inverters; reduces BOM count and layout area while maintaining <10 ns timing integrity. | Use Scenario: Expanding limited GPIO count on an ARM Cortex-M0+ MCU by driving LED indicators and relay drivers from inverted outputs. IC Role / Device Role / Timing Role: Logic-level translation and fanout buffering between MCU pins and higher-current peripheral interfaces. Use Value: Provides six independent, low-propagation-delay inverters in a 4 mm² footprint-ideal for space-constrained edge-node designs. |
| Legacy Bus Signal Re-timing | Crystal Oscillator Buffer Stage |
Use Scenario: Cleaning up and re-timing TTL-level address strobes on an 8-bit microprocessor bus running at ≤10 MHz. IC Role / Device Role / Timing Role: Waveform sharpening and skew reduction across parallel data/address lines. Use Value: Delivers matched 17 ns (max) tpd across all six channels at VCC = 4.5 V, minimizing inter-channel skew to <2 ns. | Use Scenario: Isolating and buffering a 1–20 MHz fundamental-mode quartz crystal oscillator output before distribution to multiple clock domains. IC Role / Device Role / Timing Role: Low-jitter, low-capacitance buffer stage preventing oscillator load modulation. Use Value: 3.5 pF input capacitance minimizes frequency pulling; 7 ns tpd preserves phase alignment across buffered clock paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC04PW | TSSOP14 package (4.4 mm width); Ptot = 500 mW; same electrical specs. | Better thermal performance in moderate-power applications; larger footprint limits ultra-dense routing. | Select when board space permits and thermal margin >15 °C is required at full fanout. |
| SN74LVC04APWR | TI part; 1.65–5.5 V supply; 24 mA drive; different pinout; no input clamps. | Higher drive strength but lacks overvoltage input protection; requires external clamping for >VCC signals. | Choose only if system guarantees input voltages stay within VCC ±0.3 V and higher sink/source current is mandatory. |
Compared with 74HC04PW, the 74HC04BZZ trades thermal headroom for 60% smaller PCB area and improved high-frequency signal integrity due to lower parasitic inductance. Against SN74LVC04APWR, it offers superior input ruggedness and tighter propagation delay matching-but at lower output current capability.

FAQ
Is the 74HC04BZZ pin-compatible with the 74HCT04BZZ?
Yes-the 74HC04BZZ and 74HCT04BZZ share identical pinout, package (SOT8014-1), and functional behavior. The sole difference is input threshold compatibility: 74HC uses CMOS-level inputs (VIH ≈ 0.7×VCC), while 74HCT uses TTL-level inputs (VIH = 2.0 V min). Electrical substitution is possible only if source logic matches the target input standard.
Can the thermal pad on the DHXQFN14 package be left unconnected?
Yes-the exposed thermal pad has no electrical function and may remain floating. If soldered, it must either be left electrically isolated or connected directly to GND. Do not tie it to VCC or any other voltage; doing so risks latch-up or parametric shift due to unintended substrate coupling.
What is the maximum capacitive load this device can drive reliably?
At VCC = 4.5 V and Tamb = 25 °C, the 74HC04BZZ maintains specified VOL ≤ 0.26 V and VOH ≥ 4.32 V driving up to 50 pF (per output) with tpd ≤ 17 ns. Driving >75 pF increases propagation delay nonlinearly and may cause ringing; add series termination or reduce fanout for loads exceeding this value.
Does this device support mixed-voltage interfacing (e.g., 3.3 V MCU to 5 V peripheral)?
No-the 74HC04BZZ is not a level translator. Its inputs are not 5 V tolerant when operated at 3.3 V supply (absolute max VI = VCC + 0.5 V = 3.8 V). To interface 5 V signals into a 3.3 V system, use a dedicated level-shifting solution or select the 74LVC04A, which features 5 V-tolerant inputs at 3.3 V VCC.
