Product details
Overview
74HCU04DTR2G from onsemi is a hex unbuffered inverter IC in TSSOP-14 package, operating from 2.0 V to 6.0 V, delivering 10 LSTTL load drive capability and featuring 15 pF typical power dissipation capacitance per inverter. It serves as a high-input-impedance digital signal inverter in oscillator circuits, pulse shaping, and level translation.
For engineers reviewing the 74HCU04DTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2.0–6.0 V), propagation delay (12 ns @ 6 V), input leakage current (±1.0 µA), output drive strength, and Pb-free TSSOP-14 packaging compatibility with high-density PCB layouts.
Technical Context
The 74HCU04DTR2G implements six independent CMOS inverter stages using silicon-gate technology, with no internal buffering-enabling direct use in ring oscillators and Schmitt-trigger configurations. Its inputs tolerate LSTTL levels when pulled up and interface natively with CMOS, NMOS, and TTL logic families.
It operates across –55 °C to +125 °C with guaranteed AC performance at CL = 50 pF and input rise/fall times unrestricted. The device complies with JEDEC Std. 7.0A and achieves HBM ESD robustness of 2000 V, supporting industrial and automotive-adjacent environments where noise immunity and wide temperature operation are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports single-supply operation across battery-powered (3 V) and legacy 5 V systems without level shifters |
| Propagation Delay | 12 ns max @ VCC = 6.0 V, CL = 50 pF - enables reliable timing in >30 MHz oscillator loops and fast edge reshaping |
| Output Drive | 10 LSTTL loads - sufficient to drive multiple downstream TTL inputs without external buffers |
| Input Leakage Current | ±1.0 µA max @ 125 °C - ensures stable biasing in high-impedance RC oscillator and sensor interface applications |
| Power Dissipation Cap. | 15 pF per inverter - used to calculate dynamic power: PD = CPD × VCC² × f + ICC × VCC for clocked designs |
| ESD Rating | HBM 2000 V - reduces risk of handling damage during manual assembly and board rework |
| Operating Temperature | –55 °C to +125 °C - qualified for under-hood, industrial control, and extended-range instrumentation |
Pinout & Package
TSSOP-14 package (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | CMOS-compatible high-impedance inputs; require explicit tie-high/tie-low if unused |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | Push-pull CMOS outputs; capable of sourcing/sinking ≥2.4 mA at VCC = 3.0 V |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-inductance connection |
| 14 | VCC | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Enables direct use in crystal/RC oscillators and Schmitt-trigger feedback loops without added phase delay |
| Wide Supply Range (2.0–6.0 V) | Eliminates need for separate voltage regulators in mixed-supply systems (e.g., 3.3 V MCU + 5 V peripherals) |
| High Input Impedance (>1012 Ω) | Permits high-R, low-power RC timing networks and minimizes loading on preceding analog or digital stages |
| LSTTL Load Compatibility | Drives up to 10 standard TTL inputs directly-reduces component count in legacy logic interfacing |
| Pb-Free TSSOP-14 Packaging | Supports fine-pitch automated assembly and RoHS-compliant production without lead-tin reflow compromises |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC04DR | Buffered architecture; higher propagation delay (19 ns @ 6 V); 20 pF CPD; SOIC-14 only | Less suitable for oscillator use due to added internal buffering; better for pure logic inversion with tighter fanout control | Select SN74HC04DR when deterministic propagation delay and reduced capacitive loading on driving stage are prioritized over oscillator capability |
| MC74VHC04DT | Higher speed (8 ns @ 5 V); wider VCC range (2.0–5.5 V); lower ICC (1 µA typ); TSSOP-14 | Better suited for high-frequency clock distribution but lacks 6.0 V operation and has lower noise margin at 5.5 V | Choose MC74VHC04DT for sub-10 ns timing-critical paths where 6.0 V operation is not required and ultra-low quiescent current matters |
Compared with SN74HC04DR and MC74VHC04DT, the 74HCU04DTR2G uniquely balances unbuffered gain for oscillator design, 6.0 V tolerance, and industrial temperature support-making it optimal for self-timed clock generation and ruggedized level-shifting where buffered delay or narrow voltage range would compromise system behavior.

FAQ
What is the maximum operating supply voltage for the 74HCU04DTR2G?
The 74HCU04DTR2G supports a DC supply voltage range of 2.0 V to 6.0 V, with absolute maximum rating of +7.0 V on VCC. Operation above 6.0 V is not recommended and may compromise reliability or violate JEDEC Std. 7.0A compliance. The 74HCU04DTR2G is rated for full functionality-including propagation delay and output drive-across the entire 2.0–6.0 V range.
Can the 74HCU04DTR2G be used to build a crystal oscillator?
Yes, the 74HCU04DTR2G is explicitly validated for crystal oscillator use, as shown in Figure 4 of its datasheet. Its unbuffered inverter structure provides the necessary phase inversion and gain for Pierce configurations. The 74HCU04DTR2G supports oscillator operation from 2.5 V to 6.0 V, and its low input capacitance (10 pF) and high input impedance ensure reliable start-up with standard AT-cut crystals.
Does the 74HCU04DTR2G have built-in ESD protection?
Yes, the 74HCU04DTR2G includes on-die ESD protection circuits rated at 2000 V HBM (Human Body Model) and 200 V Machine Model. This meets industrial handling requirements and reduces susceptibility to damage during PCB assembly or field service. The 74HCU04DTR2G datasheet confirms these ratings under "Features" and "Maximum Ratings" sections.
What is the pinout compatibility of the 74HCU04DTR2G with legacy logic families?
The 74HCU04DTR2G shares identical pinout with the 74LS04 and MC14069UB, enabling drop-in replacement in existing SOIC-14 or TSSOP-14 footprints. All six inverter pairs (A1/Y1 through A6/Y6), plus VCC (pin 14) and GND (pin 7), match exactly. The 74HCU04DTR2G maintains functional equivalence while offering CMOS advantages: lower power, wider voltage range, and higher noise immunity.
How does the 74HCU04DTR2G handle unused inputs and outputs?
Unused inputs of the 74HCU04DTR2G must be tied to a valid logic level-either VCC or GND-to prevent floating nodes that cause excessive supply current or erratic switching. Unused outputs should remain open (unconnected); connecting them together or to supply rails risks contention and device damage. This requirement is specified in the "DC Electrical Characteristics" and "Recommended Operating Conditions" sections of the 74HCU04DTR2G datasheet.
