Product details
Overview
74HC3G07DC,125 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR logic interfacing in mixed-voltage systems. It operates from 2.0 V to 6.0 V, supports CMOS input levels, delivers ≤25 ns propagation delay at 4.5 V, and features integrated input clamp diodes enabling safe interface to voltages exceeding VCC - commonly used in I²C bus pull-up networks and GPIO expansion circuits.
For engineers reviewing the 74HC3G07DC,125 datasheet, 74HC3G07DC,125 pinout, 74HC3G07DC,125 application, or 74HC3G07DC,125 equivalent, key selection criteria include open-drain output drive capability (5.2 mA sink at 6.0 V), -40 °C to +125 °C industrial temperature rating, VSSOP8 package footprint compatibility, and static input leakage <±0.1 μA at 6.0 V.
Technical Context
This device implements three independent non-inverting buffers, each with an open-drain output stage that requires external pull-up resistors. The inputs incorporate clamp diodes to VCC and GND, allowing current-limited overvoltage tolerance up to 6.0 V regardless of supply voltage.
It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, exhibits latch-up immunity >100 mA per JESD78 Class II Level B, and maintains stable operation across full industrial temperature range with VIH = 4.2 V (min) and VOL = 0.33 V (max) at 6.0 V/5.2 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - enables direct interface between 3.3 V and 5 V domains without level translators. |
| Propagation Delay | 7 ns (typ) to 20 ns (max) at VCC = 6.0 V - ensures timing predictability in high-speed digital control paths. |
| Output Sink Current | 5.2 mA (min) at VCC = 6.0 V, VOL ≤ 0.33 V - supports standard 1 kΩ pull-up on I²C buses up to 400 kHz. |
| Input Leakage | ±0.1 μA (max) at VCC = 6.0 V - minimizes loading on high-impedance sensor or microcontroller GPIO lines. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces field failure risk in manual handling and board assembly environments. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package; 8 leads; body width 2.3 mm; pin pitch 0.5 mm; exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A / 2A / 3A | Independent logic inputs - accept CMOS-level signals; clamp diodes allow safe overvoltage up to 6.0 V. |
| 2, 5, 7 | 3Y / 1Y / 2Y | Open-drain outputs - require external pull-up; support wired-AND/wired-OR bus topologies. |
| 4 | GND | Ground reference - must be low-impedance return path for all output sink currents. |
| 8 | VCC | Positive supply - powers internal logic; also serves as clamp diode anode for input overvoltage protection. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent open-drain buffers | Enables consolidation of three discrete level-shifting paths into one 2.3 mm × 2.0 mm footprint. |
| Input clamp diodes to VCC/GND | Permits use of series current-limiting resistors for interfacing to 12 V sensors or legacy 5 V peripherals. |
| Low dynamic power dissipation | CPD = 4 pF - limits switching power to <1 μW at 1 MHz with 5 V supply and light capacitive load. |
| High noise immunity | VIL = 1.8 V (min), VIH = 4.2 V (min) at VCC = 6.0 V - provides >2.4 V noise margin in noisy industrial environments. |
Applications
| I²C Bus Level Translation | GPIO Expansion Interface |
|---|---|
Use Scenario: Interfacing a 3.3 V microcontroller I²C master to 5 V peripheral slaves. IC Role / Device Role / Timing Role: Open-drain buffer isolates voltage domains while preserving signal integrity and bus timing compliance. Use Value: Eliminates need for dedicated bidirectional level shifters; supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C timing with <20 ns propagation skew. |
Use Scenario: Expanding MCU GPIO count to drive multiple LED indicators or status flags. IC Role / Device Role / Timing Role: Provides three additional open-drain outputs controllable via standard logic levels. Use Value: Enables shared pull-up configuration across multiple LEDs; reduces PCB routing complexity versus discrete FET solutions. |
| Industrial Sensor Signal Conditioning | Legacy System Voltage Interface |
Use Scenario: Conditioning analog sensor enable signals operating at 12 V in PLC backplane modules. IC Role / Device Role / Timing Role: Input clamp diodes and series resistor limit current to safe levels while buffering logic state. Use Value: Prevents damage from 12 V transients on 3.3 V controller inputs; maintains <100 ns total delay including RC time constant. |
Use Scenario: Connecting modern low-voltage logic to legacy 5 V TTL control buses. IC Role / Device Role / Timing Role: Acts as unidirectional voltage translator with CMOS input compatibility and 5 V-tolerant outputs. Use Value: Supports interoperability without external voltage dividers; meets JEDEC JESD8C for 3.3 V–5 V interoperation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC3G07GM,132 | Lower VCC range (1.65–5.5 V); higher speed (tPD = 3.2 ns typ at 3.3 V); no input clamp diodes. | Suitable only for 3.3 V systems; cannot tolerate >5.5 V inputs without external protection. | Select when speed >5 ns and supply is strictly 3.3 V; avoid in mixed-voltage or overvoltage-prone designs. |
| SN74LVC3G07DCUR | Same VCC range (1.65–5.5 V); identical pinout; no clamp diodes; lower ICC (<1 μA). | Lacks overvoltage input tolerance; requires external clamping for >5.5 V interfaces. | Prefer for battery-powered IoT nodes where ultra-low quiescent current is critical and voltage domains are tightly controlled. |
Compared with 74HC3G07DC,125, the LVC variants offer faster switching and lower static current but sacrifice input overvoltage resilience and 6.0 V operation - making them unsuitable for industrial sensor interfacing or legacy system integration where clamp diodes are essential.

FAQ
Can 74HC3G07DC,125 be used as a direct replacement for 74HCT3G07DC?
No - the 74HC3G07DC uses CMOS input thresholds (VIH ≥ 4.2 V at 6.0 V), while 74HCT3G07DC uses TTL-compatible inputs (VIH ≥ 2.0 V at 5.0 V). Swapping them may cause logic misreads in 5 V systems with marginal high-level signals, especially near noise margins. Verify input voltage levels before substitution.
What is the maximum recommended pull-up resistor value for 74HC3G07DC,125 outputs?
At VCC = 6.0 V and 5.2 mA sink current, the maximum pull-up is 1.15 kΩ to maintain VOL ≤ 0.33 V. For I²C fast-mode (400 kHz), 2.2 kΩ is typical with 20 pF bus capacitance, yielding rise time <300 ns. Exceeding 4.7 kΩ risks violating timing specs under worst-case load and temperature.
Does 74HC3G07DC,125 support hot-swap or live-insertion?
No - it lacks powered-off protection or Ioff specification. Applying input voltage before VCC risks forward-biasing internal clamp diodes, causing excessive current flow and potential damage. Always power VCC before applying input signals during system startup or hot-plug sequences.
Is the VSSOP8 package (SOT765-1) RoHS and REACH compliant?
Yes - Nexperia confirms SOT765-1 packaging for 74HC3G07DC,125 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound. Full compliance documentation is available via Nexperia's product change notifications and material declarations portal.
