Product details
Overview
74LVQ04SCX from ON Semiconductor is a low-voltage hex inverter IC operating at 2.0–3.6 V supply, featuring six independent CMOS inverters with guaranteed 9.5 ns max propagation delay (VCC = 3.3 V, CL = 50 pF), ±12 mA output drive, and 0.1 V max VOL at 12 mA sink current. It is used in 3.3 V digital logic interfacing, signal inversion, and clock buffering in industrial control and communications equipment.
For engineers reviewing the 74LVQ04SCX datasheet, pinout, applications, or equivalent options, key selection criteria include simultaneous switching noise immunity, pin-to-pin skew control (<1.5 ns), incident-wave switching into 75 Ω transmission lines, and guaranteed dynamic threshold performance across −40°C to +85°C.
Technical Context
The 74LVQ04SCX implements six independent CMOS inverter stages in a single monolithic die, optimized for 3.3 V operation with rail-to-rail input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 3.3 V) and fast edge handling (min input edge rate 125 mV/ns). It supports TTL-compatible inputs and drives standard CMOS loads.
Its AC performance is characterized with CL = 50 pF and includes guaranteed tPLH/tPHL ≤ 10.0 ns and output-to-output skew ≤ 1.5 ns under commercial and extended temperature ranges. Dynamic input voltage thresholds (VIHD = 2.0 V max, VILD = 0.8 V max) are specified for reliable high-speed switching on transmission lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 3.6 V - Enables direct interface with 3.3 V logic families without level shifting. |
| Propagation Delay | ≤ 10.0 ns (VCC = 3.3 V, CL = 50 pF) - Supports >50 MHz toggle rates in clean logic paths. |
| Output Drive | ±12 mA - Sufficient to drive multiple 74LVC inputs or 50 Ω transmission lines with controlled edge integrity. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V (VCC = 3.3 V) - Ensures robust noise margin against ground bounce and crosstalk. |
| Dynamic Skew | ≤ 1.5 ns - Guarantees synchronized inversion across all six channels for timing-critical bus applications. |
| Power Dissipation Cap | CPD = 17 pF - Predictable dynamic power consumption enables accurate system-level power budgeting. |
Pinout & Package
74LVQ04SCX is packaged in a 14-lead SOIC (JEDEC MS-012, 0.150" narrow body), package number M14A, with standard dual-in-line pinout and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | Dedicated CMOS input per inverter stage; must be tied HIGH/LOW if unused (no floating allowed). |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | CMOS push-pull output capable of sourcing/sinking ±12 mA with rail-aligned VOH/VOL. |
| 7 | GND | Logic ground reference; decoupling capacitor placement critical for noise suppression. |
| 14 | VCC | Primary power supply (2.0–3.6 V); requires local 0.1 µF ceramic bypass near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Simultaneous Switching Noise Immunity | Guaranteed performance under worst-case multi-output switching - reduces need for additional filtering in dense PCB layouts. |
| Incident-Wave Switching | Validated into 75 Ω transmission lines - enables direct use in video, RF front-end, and high-speed serial interconnects without termination redesign. |
| PIN-to-PIN Skew Control | ≤1.5 ns skew across all six outputs - ensures deterministic timing alignment in parallel data paths or clock fanout. |
| Low-Voltage Operation | Full functionality from 2.0 V - supports battery-powered and mixed-voltage systems with 3.3 V core logic. |
Applications
| Industrial PLC I/O Expansion | 3.3 V Bus Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APWR | Lower ICC (1 µA typ), wider VCC range (1.65–5.5 V), but no guaranteed incident-wave switching into 75 Ω. | Preferred for ultra-low-power portable designs; not validated for transmission-line driving. | Select when lowest quiescent current is critical and transmission-line impedance matching is unnecessary. |
| MC74VHC04DR2G | Higher VCC max (5.5 V), faster tPLH/tPHL (5.5 ns typ), but no guaranteed skew or dynamic threshold specs. | Better for 5 V legacy compatibility and higher-speed logic; lacks LVQ-series noise and skew guarantees. | Select when operating above 3.6 V or requiring sub-6 ns delay, accepting relaxed skew/noise specifications. |
Compared with SN74LVC04APWR and MC74VHC04DR2G, the 74LVQ04SCX uniquely delivers verified 75 Ω transmission-line switching, ≤1.5 ns skew, and simultaneous switching noise control - making it the preferred choice for timing-critical, noise-sensitive 3.3 V systems where deterministic behavior is non-negotiable.

FAQ
What is the maximum operating temperature range for the 74LVQ04SCX?
The 74LVQ04SCX is rated for operation from −40°C to +85°C, fully specified across this industrial temperature range with guaranteed AC and DC parameters including propagation delay, output drive, and input thresholds. This makes the 74LVQ04SCX suitable for deployment in uncontrolled ambient environments such as factory floors and outdoor telecom cabinets where thermal cycling occurs.
Does the 74LVQ04SCX support 5 V tolerant inputs?
No, the 74LVQ04SCX does not support 5 V tolerant inputs. Its absolute maximum input voltage is VCC + 0.5 V, and with VCC limited to 3.6 V max, inputs must remain within −0.5 V to 4.1 V. Applying 5 V signals risks latch-up or permanent damage. For mixed-voltage interfacing, external resistive dividers or dedicated level translators are required alongside the 74LVQ04SCX.
What package type is used for the 74LVQ04SCX?
The 74LVQ04SCX uses a 14-lead Small Outline Integrated Circuit (SOIC) package, JEDEC MS-012 compliant, 0.150" narrow body, package number M14A. This surface-mount package has gull-wing leads, 1.27 mm pitch, and is RoHS-compliant. The "X" suffix denotes tape-and-reel packaging for automated assembly.
Can unused inputs on the 74LVQ04SCX be left floating?
No, unused inputs on the 74LVQ04SCX must never be left floating. Per the datasheet, all unused inputs must be tied either HIGH (to VCC) or LOW (to GND) to prevent undefined logic states, increased power consumption, and potential oscillation. Floating inputs can cause excessive ICC, noise coupling, and erratic output behavior - especially under temperature or voltage variation.
Is the 74LVQ04SCX pin-compatible with other 74LV series hex inverters?
Yes, the 74LVQ04SCX shares the same 14-pin SOIC footprint and pinout as standard 74LV04 and 74LVC04 devices - pin 1 is A1, pin 2 is Y1, ..., pin 14 is VCC. However, functional differences exist: the "Q" suffix denotes enhanced simultaneous switching noise and skew performance not guaranteed in baseline LV/LVC variants. So while PCB layout is compatible, timing and noise behavior require verification per application.
