Product details
Overview
74HCT3G06DC,125 from Nexperia is a triple inverter IC with open-drain outputs, designed for level-shifting and wired-AND logic interfacing in mixed-voltage systems. It operates from 4.5 V to 5.5 V, accepts TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V), delivers <0.33 V low-level output at 4.0 mA load, and is qualified from –40 °C to +125 °C in VSSOP8 package.
For engineers reviewing the 74HCT3G06DC,125 datasheet, 74HCT3G06DC,125 pinout, 74HCT3G06DC,125 application, or 74HCT3G06DC,125 equivalent, key selection criteria include open-drain drive capability, TTL-compatible input thresholds, propagation delay (9–29 ns), thermal robustness up to +125 °C, and compatibility with I²C bus pull-up configurations.
Technical Context
This device implements three independent inverting buffers with open-drain outputs, enabling shared-bus signaling and voltage-level translation without internal pull-ups. Each channel features input clamp diodes supporting current-limiting resistor interfaces to voltages exceeding VCC.
It complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), supports HBM ESD >2000 V and CDM >1000 V, and meets latch-up immunity >100 mA per JESD78 Class II Level B - confirming suitability for industrial control and sensor interface applications demanding reliability across extended temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with 5 V TTL and mixed 3.3/5 V system rails |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of standard TTL logic levels |
| Output Drive | IO = 4.0 mA @ VOL ≤ 0.33 V - enables direct connection to 5 V pull-up resistors in I²C or SMBus |
| Propagation Delay | tPZL/tPLZ = 9–29 ns @ VCC = 4.5 V - supports data rates up to ~10 MHz in timing-critical bus interfaces |
| Operating Temperature | –40 °C to +125 °C - validated for under-hood automotive modules and industrial motor drives |
| ESD Robustness | HBM >2000 V, CDM >1000 V - reduces susceptibility to handling damage during PCB assembly |
| Input Leakage | ±1.0 μA max @ VCC = 5.5 V - minimizes loading on high-impedance signal sources like microcontroller GPIO |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8-pin, body width 2.3 mm, 0.5 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A / 2A / 3A | Independent logic inputs - each drives one inverter stage; accept TTL-level signals |
| 2, 5, 7 | 3Y / 2Y / 1Y | Open-drain outputs - require external pull-up; support wired-AND and bidirectional bus operation |
| 4 | GND | Ground reference - all voltage measurements referenced here; must be low-impedance return path |
| 8 | VCC | Positive supply - powers internal CMOS circuitry; bypass capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Triple open-drain inverters | Enables three independent wired-AND nodes or I²C-style bus drivers in one compact footprint |
| TTL-compatible inputs | Eliminates need for external level shifters when interfacing with legacy 5 V microcontrollers or logic |
| Input clamp diodes | Allows safe interface to voltages >VCC using series current-limiting resistors (e.g., 12 V sensor signals) |
| –40 °C to +125 °C operation | Validated for use in engine control units, industrial PLC I/O modules, and power supply monitoring circuits |
| Low ICC (≤20 μA) | Reduces quiescent current in always-on subsystems such as battery-backed real-time clock supervisors |
Applications
| I²C Bus Buffering | Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Isolating and extending I²C bus segments across PCB sections with different supply domains. IC Role / Device Role / Timing Role: Open-drain inverter acting as unidirectional bus repeater - inverts SDA/SCL logic while preserving open-drain behavior. Use Value: Enables 5 V master to communicate with 3.3 V slave devices via pull-up resistors on each side; eliminates contention during hot-plug events. |
Use Scenario: Converting analog comparator outputs or Hall-effect sensor pulses into clean, rail-to-rail digital signals. IC Role / Device Role / Timing Role: Inverting buffer with noise-immune TTL thresholds - cleans up slow-rising or noisy edges before MCU capture. Use Value: VIH/VIL margins >1.2 V reject EMI-induced glitches; 9 ns tPLZ ensures accurate timing capture of fast edge transitions. |
| Industrial Control Logic | Power Sequencing Monitor |
|
Use Scenario: Implementing safety interlocks and enable/disable logic in motor drive gate driver stages. IC Role / Device Role / Timing Role: Triple inverter providing isolated enable inversion, fault signal inversion, and status feedback inversion. Use Value: Single-package solution reduces board area vs discrete transistors; 125 °C rating matches gate driver thermal environment. |
Use Scenario: Monitoring power-good signals from multiple DC-DC converters to generate a consolidated system reset. IC Role / Device Role / Timing Role: Wired-AND combiner - all inverted PG signals tied together to pull down RESET line if any converter fails. Use Value: Open-drain outputs allow direct OR-ing without additional diodes; low VOL ensures solid logic-low assertion of reset. |
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 |
|---|---|---|---|
| 74LVC3G06GW,125 | Wider VCC range (1.65–5.5 V); LVCMOS inputs; lower VOL (0.26 V @ 24 mA) | Better suited for 1.8 V/3.3 V systems; higher drive strength may overload weak pull-ups | Select when interfacing with sub-3.3 V logic or requiring faster edge rates; verify pull-up resistor sizing. |
| SN74LVC3G06DCUR | Same VCC range; identical pinout; slightly higher ICC (max 40 μA vs 20 μA) | Functionally interchangeable but less optimized for ultra-low-power always-on monitoring | Prefer for TI-based designs where toolchain and qualification alignment outweigh minor power penalty. |
Compared with 74LVC3G06GW,125 and SN74LVC3G06DCUR, the 74HCT3G06DC,125 offers superior noise immunity and tighter TTL threshold matching for legacy 5 V systems, while maintaining lower static current and proven thermal stability at +125 °C - making it optimal for industrial and automotive-adjacent control applications.

FAQ
Can 74HCT3G06DC,125 drive an I²C bus directly?
Yes - its open-drain outputs and TTL-compatible inputs make it suitable for I²C bus buffering or level translation. Connect external pull-up resistors to the desired bus voltage (e.g., 3.3 V or 5 V), ensure VCC matches the controller side, and verify timing margins using tPLZ/tPZL values (9–29 ns) against target clock frequency.
What is the maximum sink current per output?
The absolute maximum output current is 25 mA per channel (per limiting values table), but the recommended operating condition specifies 4.0 mA with VOL ≤ 0.33 V at VCC = 4.5 V. For reliable long-term operation, limit continuous sink current to ≤4 mA unless derated per thermal conditions.
Does this device require external pull-up resistors on outputs?
Yes - all three outputs (1Y, 2Y, 3Y) are open-drain and cannot source current. External pull-up resistors must be used to establish HIGH logic levels; typical values range from 1 kΩ to 10 kΩ depending on bus capacitance and speed requirements.
How does the input clamp diode affect interfacing with voltages above VCC?
The integrated input clamp diodes allow safe connection of signals up to 7.0 V (absolute max) when used with series current-limiting resistors. For example, a 12 V sensor output can be interfaced using a 10 kΩ resistor - limiting IIK to <20 mA and preventing damage while preserving logic integrity.
