Product details
Overview
74LVQ04SJX from ON Semiconductor is a low-voltage hex inverter IC operating at 2.0–3.6 V supply, delivering six independent CMOS inverters with guaranteed 9.5 ns max propagation delay (tPHL/tPLH @ 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 buffering, signal inversion, and clock conditioning in industrial control and communications interfaces.
For engineers reviewing the 74LVQ04SJX datasheet, pinout, applications, or equivalent options, key selection criteria include its guaranteed simultaneous switching noise performance, incident-wave switching into 75 Ω transmission lines, pin-to-pin skew control, and EIAJ TYPE II SOP-14 package compatibility for space-constrained PCB layouts.
Technical Context
The 74LVQ04SJX implements six independent CMOS inverter stages with rail-to-rail input thresholds (VIH = 2.0 V min, VIL = 0.8 V max @ VCC = 3.3 V) and TTL-compatible output swing. Its AC performance is characterized under controlled load (CL = 50 pF) and specified across −40°C to +85°C.
Designed for low-noise 3.3 V systems, it guarantees dynamic input voltage thresholds (VIHD = 2.0 V, VILD = 0.8 V), quiet-output dynamic VOL/VOLP behavior, and simultaneous switching noise immunity-critical for mixed-signal board environments where signal integrity must be preserved during multi-output transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - supports standard 3.3 V logic rails with 10% tolerance margin |
| Propagation Delay | 9.5 ns max (tPHL/tPLH @ 3.3 V, CL = 50 pF) - enables reliable timing in ≤100 MHz edge-triggered paths |
| Output Drive | ±12 mA - sufficient to drive 50 Ω transmission lines or fan-out to ≥10 LVTTL inputs |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max @ VCC = 3.3 V - ensures robust noise margin against ground bounce |
| Dynamic VOL | 0.44 V max @ IOL = 12 mA - maintains logic LOW integrity under heavy capacitive or resistive loads |
| Power Dissipation Cap | CPD = 17 pF @ 3.3 V - allows accurate dynamic power estimation at 10 MHz toggle rate |
Pinout & Package
74LVQ04SJX is housed in a 14-lead Small Outline Package (SOP), EIAJ TYPE II, 5.3 mm wide (Package Number M14D), with gull-wing leads and standard 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Inverter Input (A1–A6) | Digital logic inputs accepting 0–VCC voltage levels; must not float - tie unused pins HIGH/LOW |
| 2, 4, 6, 8, 10, 12 | Inverter Output (Y1–Y6) | CMOS push-pull outputs sourcing/sinking up to ±12 mA; rail-to-rail swing |
| 7 | GND | Ground reference for all logic and power domains; requires low-impedance PCB connection |
| 14 | VCC | Primary supply pin for all six inverters; bypassing with 0.1 µF ceramic capacitor recommended |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed pin-to-pin skew | ≤1.5 ns (tOSHL/tOSLH) - ensures synchronized inversion across all six channels for clock fanout |
| Incident-wave switching into 75 Ω | Validated for transmission-line driving without termination - reduces board-level stubs and layout complexity |
| Simultaneous switching noise control | Specified dynamic VOLP/VOLV limits (±1.1 V @ 3.3 V) - prevents false triggering in adjacent logic |
| Low quiescent ICC | 20 µA max @ VCC = 3.6 V - supports battery-backed or always-on subsystems with minimal standby drain |
Applications
| Industrial PLC I/O Conditioning | 3.3 V UART Signal Inversion |
|---|---|
Use Scenario: Inverting sensor status signals (e.g., limit switch closures) before feeding into microcontroller GPIOs with active-low interrupt triggers. IC Role / Device Role / Timing Role: Level-shifting and polarity correction for open-collector/drain interface signals in noisy factory environments. Use Value: Guaranteed 0.44 V VOL at 12 mA ensures clean LOW detection despite cable capacitance and EMI-induced voltage rise on shared grounds. | Use Scenario: Converting RS-232-style inverted logic (TxD/RxD) to native MCU UART logic levels in embedded serial gateways. IC Role / Device Role / Timing Role: Single-supply logic inversion stage between legacy transceivers and 3.3 V SoCs. Use Value: 9.5 ns max propagation delay preserves UART timing margins at 115.2 kbps with 16× oversampling, avoiding bit sampling errors. |

Use Scenario: Distributing a system clock to multiple FPGA configuration or ADC sampling clocks while maintaining edge alignment. IC Role / Device Role / Timing Role: Low-skew fanout buffer providing six phase-aligned inverted copies of a master clock. Use Value: ≤1.5 ns output-to-output skew ensures sub-cycle timing correlation across distributed clock domains. | Use Scenario: Enabling/disabling high-current LED drivers via microcontroller GPIOs that require active-HIGH enable but driver accepts active-LOW. IC Role / Device Role / Timing Role: Polarity translation for enable/control signals in lighting control modules. Use Value: ±12 mA drive capability directly switches driver EN pins without external transistor staging, reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC04APW | Higher VCC range (1.65–5.5 V); 5.5 ns typical tPD @ 3.3 V; no guaranteed incident-wave spec | Better suited for mixed-voltage systems; lacks 75 Ω transmission-line validation | Select when wider supply flexibility or faster typical speed is prioritized over transmission-line integrity guarantees |
| MC74VHC04DR2 | Same 2.0–3.6 V range; 7.5 ns max tPD; no dynamic threshold or skew specs published | Lower static power (ICC < 2 µA), but no guaranteed simultaneous switching noise performance | Select for ultra-low-quiescent-power applications where skew and noise immunity are secondary |
Compared with SN74LVC04APW and MC74VHC04DR2, the 74LVQ04SJX uniquely provides documented incident-wave switching into 75 Ω and guaranteed output skew - making it preferred for high-integrity signal routing in industrial backplanes and timing-critical interfaces where deterministic behavior under load is mandatory.

FAQ
What is the maximum operating temperature range for the 74LVQ04SJX?
The 74LVQ04SJX is rated for operation from −40°C to +85°C ambient temperature. This industrial-grade range ensures reliable functionality in factory automation controllers, outdoor communication nodes, and motor drive interface modules where thermal cycling and extended temperature exposure occur. All electrical specifications-including propagation delay, output drive, and noise immunity-are guaranteed across this full range.
Does the 74LVQ04SJX support 2.5 V supply operation?
Yes, the 74LVQ04SJX supports 2.5 V supply operation within its specified VCC range of 2.0 V to 3.6 V. At 2.5 V, VIH is guaranteed ≥1.7 V and VIL ≤0.7 V, preserving adequate noise margin. Propagation delay increases to ~12.7 ns max (tPHL/tPLH), and output drive reduces to ±8 mA, which remains sufficient for light-load logic interfacing and low-speed control signaling.
Is the 74LVQ04SJX pin-compatible with standard 74HC04 or 74LS04 devices?
No, the 74LVQ04SJX is not pin-compatible with 74HC04 or 74LS04. While all are 14-pin hex inverters with identical pin numbering (inputs on odd pins, outputs on even pins, VCC on 14, GND on 7), the 74LVQ04SJX is designed exclusively for 3.3 V operation and lacks 5 V tolerance. Interfacing with 5 V logic requires level translation, and substituting it for 74LS04 introduces incompatible drive strength and threshold levels that may cause functional failure.
What is the meaning of "incident-wave switching into 75 Ω" for the 74LVQ04SJX?
"Incident-wave switching into 75 Ω" means the 74LVQ04SJX is characterized to drive unterminated 75 Ω coaxial or PCB transmission lines without signal reflection-induced overshoot or ringing during the initial edge transition. This capability-guaranteed across −40°C to +85°C-enables direct connection to video lines, RF front-end controls, or legacy telecom interfaces without external series termination, simplifying layout and improving signal integrity in high-speed edge-sensitive paths.
Can unused inputs on the 74LVQ04SJX be left floating?
No, unused inputs on the 74LVQ04SJX must never be left floating. The datasheet explicitly states that unused inputs must be held HIGH or LOW-either tied to VCC or GND through a pull-up/pull-down resistor (typically 10 kΩ). Floating inputs can cause increased ICC, erratic output behavior, excessive power dissipation, and potential latch-up due to intermediate voltage states violating CMOS input threshold stability requirements.
