Product details
Overview
74HCT3G07GD,125 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level translation and wired-AND bus interfacing in mixed-voltage systems. It operates from 4.5 V to 5.5 V, supports TTL-level inputs, delivers ≤0.33 V low-level output at 4.0 mA load, and functions across -40 °C to +125 °C - used in I²C bus pull-up control and microcontroller GPIO expansion.
For engineers reviewing the 74HCT3G07GD,125 datasheet, 74HCT3G07GD,125 pinout, 74HCT3G07GD,125 application, or 74HCT3G07GD,125 equivalent, key selection criteria include open-drain drive capability, TTL-compatible input thresholds, thermal performance in TSSOP8, and compatibility with 3.3 V/5 V mixed-signal interfaces.
Technical Context
This device implements three independent non-inverting buffers, each with an open-drain output stage enabling shared-bus operation and voltage-level flexibility. Input clamp diodes allow safe interfacing to signals exceeding VCC when current-limiting resistors are used.
It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, features ±1.0 μA max input leakage at 5.5 V, and exhibits 11 ns typical tPZL propagation delay (OFF→LOW) at VCC = 4.5 V and Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL logic rails and robust noise margin. |
| Input Threshold (VIH/VIL) | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL logic levels at 5 V supply. |
| Output Drive (VOL) | ≤0.33 V at IO = 4.0 mA - enables strong LOW assertion on shared buses with minimal voltage drop. |
| Propagation Delay (tPZL) | 11 ns typical (OFF→LOW), 10 ns typical (LOW→OFF) - supports >20 MHz bus toggle rates in I²C-compatible designs. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor control PCBs. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly. |
| Input Capacitance (CI) | 1.5 pF - minimizes capacitive loading on high-speed MCU GPIO lines and preserves signal integrity. |
Pinout & Package
The 74HCT3G07GD,125 is housed in a 8-pin XSON8 (SOT996-2) package: 2.1 mm × 1.6 mm body, 0.5 mm pitch, no leads, bottom-side thermal pad. This ultra-compact leadless package supports high-density routing and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | Input (1A, 2A, 3A) | Three independent TTL-level digital inputs; each includes internal clamp diodes for overvoltage tolerance. |
| 2, 5, 7 | Open-drain Output (3Y, 1Y, 2Y) | Active-Low outputs requiring external pull-up; enable wired-AND logic and bidirectional bus arbitration. |
| 4 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance for noise immunity. |
| 8 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor required within 3 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - eliminates need for external level shifters when driving from legacy 5 V controllers. |
| Open-drain outputs | Three independent n-channel MOSFET outputs - support I²C, SMBus, and 1-Wire protocols without external FETs. |
| Wide temperature range | Specified from -40 °C to +125 °C - validated for use in automotive engine control units and industrial PLC I/O modules. |
| Low input leakage | ±1.0 μA max at 5.5 V and 125 °C - prevents unintended logic state changes in high-impedance sensor interface circuits. |
| Clamp diode protection | Integrated input diodes to VCC and GND - allows safe connection to 12 V or 24 V signals using series current-limiting resistors. |
Applications
| I²C Bus Level Translation | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Interfacing a 3.3 V ARM Cortex-M microcontroller I²C port to 5 V peripheral sensors. IC Role / Device Role / Timing Role: Acts as bidirectional level translator via open-drain outputs and pull-up resistors on both sides of the bus. Use Value: Eliminates discrete MOSFET translators; maintains I²C timing compliance with <25 ns propagation delay and <20 pF total capacitance. | Use Scenario: Expanding limited GPIO count on an STM32WB55 to drive multiple LED indicators and status flags. IC Role / Device Role / Timing Role: Provides three additional open-drain outputs controllable by MCU firmware, sharing a single pull-up resistor per line. Use Value: Reduces BOM count vs. discrete transistors; supports 4.0 mA sink per output for direct LED drive without external drivers. |
| Industrial Sensor Interface | Automotive Body Control Module |
Use Scenario: Conditioning digital alarm signals from analog sensor comparators operating at 12 V supply. IC Role / Device Role / Timing Role: Buffers comparator outputs and translates them to 5 V logic levels compatible with MCU inputs. Use Value: Clamp diodes permit direct 12 V input connection with only one series resistor per channel; -40 °C to +125 °C rating matches sensor environment. | Use Scenario: Driving LIN bus wake-up lines and diagnostic LEDs in door module ECUs. IC Role / Device Role / Timing Role: Provides ESD-hardened, temperature-stable open-drain outputs for LIN physical layer signaling and status indication. Use Value: HBM > 2000 V and AEC-Q200 alignment (via extended temp range) reduce field return risk in harsh automotive environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC3G07GM,125 | CMOS inputs (VIH = 0.7×VCC), 1.65–5.5 V supply - lower static power but less tolerant of 5 V TTL inputs. | Preferred for 3.3 V-only systems; unsuitable for direct 5 V TTL source interfacing without level shifting. | Select when system uses only 3.3 V logic and lowest quiescent current (<10 μA) is critical. |
| SN74LVC3G07DCUR | VSSOP8 package (2.3 mm width), same electrical specs - larger footprint but easier rework and probing. | Better suited for prototyping and low-volume industrial controls where hand-soldering or test access matters. | Choose when TSSOP8 or XSON8 assembly capability is unavailable, or when thermal pad inspection is impractical. |
Compared with 74LVC3G07GM,125 and SN74LVC3G07DCUR, the 74HCT3G07GD,125 uniquely combines TTL input compatibility, XSON8 space savings, and automotive-grade temperature range - making it optimal for cost-sensitive, high-density 5 V mixed-signal designs.

FAQ
Can 74HCT3G07GD,125 drive an I²C bus directly?
Yes - its open-drain outputs, low VOL (≤0.33 V at 4 mA), and 1.5 pF input capacitance meet I²C Standard Mode (100 kHz) and Fast Mode (400 kHz) requirements. External pull-up resistors (typically 2.2 kΩ to 5 V) are required on SDA/SCL lines, and bus capacitance must remain ≤400 pF.
What is the maximum sink current per output?
The absolute maximum sink current is 25 mA per output (per limiting values table), but the recommended operating condition specifies 4.0 mA for VOL ≤0.33 V at VCC = 4.5 V. Exceeding 4.0 mA increases VOL and may violate I²C or other protocol voltage thresholds.
Does this device require external pull-up resistors?
Yes - all three outputs are open-drain and cannot source current. Each output must be pulled up to a defined voltage rail (e.g., 3.3 V or 5 V) via an external resistor. Typical values range from 1.8 kΩ (for fast rise time) to 10 kΩ (for low power), depending on bus capacitance and speed requirements.
Is 74HCT3G07GD,125 pin-compatible with 74HC3G07GD,125?
Yes - both share identical XSON8 (SOT996-2) pinout and footprint. However, 74HC3G07GD,125 uses CMOS input thresholds (VIH = 3.15 V at 4.5 V), while 74HCT3G07GD,125 uses TTL thresholds (VIH = 2.0 V), making the latter compatible with older 5 V TTL sources without level shifting.
