Product details

Overview

74LVC3G06SS8-7 from Diodes Incorporated is a triple inverter IC with open-drain outputs, designed for voltage-level shifting and power-down signal isolation in mixed-voltage systems. It operates across 1.65V–5.5V supply, tolerates 5.5V inputs, delivers –24mA output drive at 3.3V, and supports IOFF partial power-down mode. Used in notebook I/O control, peripheral interface isolation, and embedded logic translation.

For engineers reviewing the 74LVC3G06SS8-7 datasheet, 74LVC3G06SS8-7 pinout, 74LVC3G06SS8-7 application, or 74LVC3G06SS8-7 equivalent, key selection criteria include open-drain compatibility with external pull-ups, IOFF-enabled backflow protection during power sequencing, input voltage tolerance in multi-rail designs, and VSSOP-8 thermal performance (θ_JA = 155°C/W).

Technical Context

The 74LVC3G06SS8-7 implements three independent CMOS inverters, each with an open-drain output requiring an external pull-up resistor to establish HIGH logic level. Its IOFF circuit actively disables outputs when V_CC = 0V, preventing current backflow into powered subsystems during partial power-down sequences.

Input thresholds are V_IH = 0.65×V_CC (min) at 1.65–1.95V and 0.7×V_CC (min) at 4.5–5.5V; V_IL = 0.35×V_CC (max) at low V_CC, ensuring robust noise margins. Propagation delay is 1.0ns (min) to 4.0ns (max) at 3.3V over –40°C to +125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65V to 5.5V - Enables direct interfacing between 1.8V, 2.5V, 3.3V, and 5V logic domains without level translators.
Input Voltage Tolerance	Up to 5.5V - Allows safe connection of 5V signals to lower-V_CC systems (e.g., 1.8V microcontroller GPIO).
Output Drive (I_OL)	–24mA at V_CC = 3.0V - Sinks sufficient current for driving LEDs, MOSFET gates, or standard TTL loads with external pull-up.
IOFF Leakage	±10μA max at V_I/V_O = 5.5V - Ensures negligible current flow during system sleep, critical for battery-backed or hot-swap applications.
Propagation Delay (t_PD)	1.0ns to 4.0ns at 3.3V - Supports high-speed digital control paths in real-time I/O conditioning and enable/disable sequencing.
ESD Protection	2kV HBM, 1kV CDM - Meets industrial-grade robustness requirements for board-level handling and field operation.

Pinout & Package

VSSOP-8 package: ultra-thin, lead-free, RoHS-compliant surface-mount outline (2.0mm × 2.3mm footprint, 0.5mm pitch), optimized for space-constrained portable electronics.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A	Data Input	Three independent logic inputs; each controls one inverter stage; 5.5V-tolerant regardless of V_CC.
1Y, 2Y, 3Y	Open-Drain Output	Three active-low, current-sinking outputs; require external pull-up resistors to define HIGH state voltage level.
V_CC	Supply Voltage	Single positive supply rail (1.65–5.5V); powers internal logic and enables IOFF functionality.
GND	Ground Reference	Common return path for all inputs, outputs, and internal circuitry; must be low-impedance for noise immunity.

Key Features

Feature	Design Value
IOFF Partial Power-Down Support	Automatically disables outputs when V_CC = 0V, eliminating backfeed risk during hot-plug or staged power sequencing.
Wide Supply Range (1.65–5.5V)	Eliminates need for separate level-shifting ICs in multi-voltage PCBs-e.g., 3.3V MCU controlling 5V peripherals.
5.5V-Tolerant Inputs	Accepts legacy 5V logic signals directly into low-voltage systems without clamping diodes or resistive dividers.
Low Dynamic Power (CPD = 3pF typ @ 3.3V)	Reduces switching current draw and heat generation in high-frequency enable/control lines (e.g., display backlight PWM).

Applications

PC & Notebook I/O Control

Hard Disk Drive Enable Logic

Use Scenario: Isolating USB/PCIe reset lines and SMBus address lines between 3.3V host controller and 5V peripheral modules.

IC Role / Device Role / Timing Role: Open-drain inverter provides bidirectional voltage translation and ensures clean, glitch-free reset assertion during power-up sequencing.

Use Value: Eliminates discrete MOSFET-based level shifters while maintaining <1ns propagation skew across three independent channels.

Use Scenario: Driving HDD spin-up enable and activity LED signals in portable storage enclosures with mixed 1.8V/3.3V/5V rails.

IC Role / Device Role / Timing Role: Inverts host-side active-high enable signals to active-low drive for disk motor control and sinks LED current via open-drain outputs.

Use Value: Single 8-pin VSSOP replaces three discrete inverters and two current-limiting resistors, reducing BOM count and layout area by 65%.

Set-Top Box Power Sequencing

GPS Module Interface Isolation

Use Scenario: Managing standby-to-active transitions in multi-chip STB platforms where SoC, tuner, and audio codec power domains activate asynchronously.

IC Role / Device Role / Timing Role: IOFF-enabled inverters isolate powered-down domains (e.g., tuner) from active ones (e.g., HDMI controller) during deep-sleep states.

Use Value: Prevents >100μA leakage-induced wake-up events and ensures reliable 10-year shelf-life compliance per IEC 62368-1.

Use Scenario: Interfacing 1.8V GPS baseband processor UART/IRQ lines with 3.3V GNSS antenna module requiring inverted interrupt polarity.

IC Role / Device Role / Timing Role: Provides level-shifted, inverted interrupt signaling with sub-4ns delay and zero cross-talk between RX/TX/IRQ channels.

Use Value: Enables direct connection without external biasing, reducing RF noise coupling and meeting EN 301 489-1 EMI limits for handheld navigation devices.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple open-drain inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G06DCUR	TSSOP-8 package (3.0mm × 3.0mm), θ_JA = 130°C/W; identical electrical specs and pinout.	Better thermal dissipation in high-density industrial PCBs; larger footprint less suitable for ultra-portable designs.	Select when board layout allows 3mm × 3mm area and higher continuous power dissipation is required.
74AUP3G06GM,132	Lower V_CC range (0.8–3.6V); I_OL = –4mA @ 1.2V; no 5.5V input tolerance.	Optimized for ultra-low-power wearables; incompatible with 5V signal domains or mixed-rail systems above 3.6V.	Choose only for sub-1V to 3.3V battery-powered applications where 5V tolerance is unnecessary.

Compared with SN74LVC3G06DCUR, the 74LVC3G06SS8-7 offers superior space efficiency and higher thermal resistance-critical for fanless notebooks-but requires tighter soldering process control due to 0.5mm pitch. Versus 74AUP3G06GM, it trades ultra-low static power for full 5V interoperability and stronger drive capability.

FAQ

What is the minimum recommended pull-up resistor value for 74LVC3G06SS8-7 outputs?

The minimum pull-up resistor is determined by worst-case sink current and desired VOH. At VCC = 3.3V and IOL = 24mA, a 100Ω resistor yields VOH ≈ 0.9V (below VIH), so ≥1kΩ is typical. For 3.3V systems with 10ns rise time, 4.7kΩ–10kΩ balances speed and power. Always verify against load capacitance and timing budget using tPLZ/tPZL data from the datasheet.

Can 74LVC3G06SS8-7 drive a standard LED directly?

Yes-each open-drain output can sink up to 24mA at 3.0V VCC, sufficient for most indicator LEDs (e.g., 20mA red/green at 2V forward voltage). Connect LED anode to VCC (same or higher than 74LVC3G06SS8-7 VCC) and cathode to output pin; no series resistor needed if VCC ≤ 2.2V, otherwise add resistor to limit current to ≤24mA.

Does 74LVC3G06SS8-7 require external decoupling capacitors?

Yes-per Diodes' layout guidelines, a 100nF ceramic capacitor must be placed between VCC and GND within 3mm of the VSSOP-8 package. This suppresses supply transients caused by simultaneous switching of all three inverters and maintains stable IOFF behavior during power transitions.

Is 74LVC3G06SS8-7 qualified for automotive applications?

No-the 74LVC3G06SS8-7 is not AEC-Q100 qualified. Diodes offers the automotive-grade 74LVC3G06W5-7 (WSON-8) variant for automotive use. The SS8-7 version is rated for industrial temperature range (–40°C to +125°C) but lacks PPAP documentation, IATF 16949 manufacturing certification, or stress-test validation required for automotive ECUs.
