Product details
Overview
74HCT3G07DC,125 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR logic applications in mixed-voltage systems. It operates from 4.5 V to 5.5 V, supports TTL-level inputs, delivers ≤0.4 V low-level output at 4.0 mA load, and functions across -40 °C to +125 °C - used in I²C bus buffering, LED sink drivers, and voltage-level translation between 3.3 V and 5 V domains.
For engineers reviewing the 74HCT3G07DC,125 datasheet, 74HCT3G07DC,125 pinout, 74HCT3G07DC,125 application, or 74HCT3G07DC,125 equivalent, key selection criteria include open-drain drive capability, TTL-compatible input thresholds, thermal performance in VSSOP8, and compatibility with 5 V logic buses requiring pull-up external resistors.
Technical Context
This device implements three independent non-inverting buffers, each with an open-drain output stage enabling wired-OR connectivity and bidirectional voltage translation. Input clamp diodes allow safe interfacing to voltages 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 maintains propagation delays of 11–32 ns (tPZL/tPLZ) over temperature under 4.5 V operation - optimized for noise-immune digital signal conditioning in industrial control and sensor interface circuits.
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 systems and stable operation across industrial temperature range. |
| Input Threshold (VIH/VIL) | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL logic levels without level-shifter circuitry. |
| Output Drive (VOL) | ≤ 0.4 V at IO = 4.0 mA - enables robust low-state sinking for driving LEDs, MOSFET gates, or I²C bus lines with external pull-ups. |
| Propagation Delay | tPZL/tPLZ = 11–32 ns - supports data rates up to ~10 MHz in timing-critical buffered paths. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, motor drives, and industrial PLC I/O stages. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - provides robust handling during PCB assembly and field service without additional protection components. |
| Input Capacitance | 1.5 pF - minimizes loading on high-speed source signals and preserves signal integrity in dense routing layouts. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, body width 2.3 mm, lead pitch 0.65 mm - optimized for space-constrained PCBs in portable and automotive electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 (1A, 2A, 3A) | Buffer input | Three independent TTL-compatible digital inputs accepting 0–5.5 V; clamp diodes permit overvoltage-safe interfacing. |
| 2, 5, 7 (1Y, 2Y, 3Y) | Open-drain output | Three active-low sinking outputs requiring external pull-up resistors; enable wired-OR logic and I²C-style bidirectional signaling. |
| 4 | GND | Ground reference for all internal circuitry and ESD protection paths; must be low-impedance connection to system ground plane. |
| 8 | VCC | Primary power supply rail (4.5–5.5 V); decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Triple open-drain buffer | Enables independent control of three separate wired-OR nodes - e.g., interrupt merging, multi-sensor alert lines, or shared status flags. |
| TTL-input compatibility | Accepts standard 5 V TTL logic thresholds without external biasing, simplifying integration into legacy microcontroller peripheral interfaces. |
| Wide temperature range | Rated from -40 °C to +125 °C - validated for use in engine control units, power inverters, and outdoor industrial gateways. |
| Low input leakage | ≤ ±1.0 μA at 5.5 V - prevents unintended logic state shifts in high-impedance sensor or switch input circuits. |
| High noise immunity | CMOS process with hysteresis-free inputs and 40 % noise margin at 5 V - resists EMI-induced glitches in electrically noisy motor drive environments. |
Applications
| I²C Bus Buffering | LED Sink Driver |
|---|---|
|
Use Scenario: Isolating and extending I²C bus segments in multi-node sensor networks where capacitance exceeds 400 pF. IC Role / Device Role / Timing Role: Open-drain buffer replicating SDA/SCL signals while breaking capacitive loading and ground loop coupling between segments. Use Value: Enables reliable 400 kHz I²C communication across 2+ meter cable runs using standard 4.7 kΩ pull-ups and no protocol changes. |
Use Scenario: Driving multiple indicator LEDs from a 5 V microcontroller GPIO with current limiting external to the IC. IC Role / Device Role / Timing Role: Low-side switch buffer providing controlled current sink path; each output independently manages one LED cathode. Use Value: Delivers consistent 4–10 mA LED current per channel with <0.4 V saturation drop, eliminating need for discrete MOSFETs or transistors. |
| Voltage-Level Translator | Interrupt Signal Aggregation |
|
Use Scenario: Interfacing 3.3 V sensors to a 5 V host MCU where bidirectional level shifting is not required. IC Role / Device Role / Timing Role: Unidirectional translator using 3.3 V input logic and 5 V pull-up on open-drain output to generate valid 5 V logic levels. Use Value: Achieves clean 5 V HIGH/LOW transitions without shoot-through current or timing skew - unlike passive resistor dividers. |
Use Scenario: Combining interrupt requests from multiple peripherals (e.g., ADC, UART, timer) into a single MCU IRQ line. IC Role / Device Role / Timing Role: Wired-OR combiner where any active-low interrupt pulls the shared line LOW; each buffer isolates source impedance. Use Value: Prevents contention and backfeeding between interrupt sources while maintaining sub-32 ns worst-case assertion delay. |
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), CMOS inputs, higher speed (tPD = 3.2 ns @ 3.3 V), but only rated to +85 °C. | Suitable for portable 3.3 V systems; unsuitable for under-hood or industrial ambient >85 °C. | Select when operating below 3.3 V or requiring faster edge rates; verify thermal derating in enclosed enclosures. |
| SN74LVC3G07DCUR | Same VCC range (1.65–5.5 V), CMOS inputs, +125 °C rating, but larger TSSOP8 (SOT505-2) footprint and 2× higher ICC (20 μA vs 10 μA). | Compatible pinout but requires PCB rework; higher supply current impacts battery-powered designs. | Choose only if VSSOP8 footprint is unavailable and thermal design accommodates increased power dissipation. |
Compared with 74HCT3G07DC,125, the 74LVC3G07GM,132 offers superior speed and lower-voltage flexibility but sacrifices high-temperature reliability, while the SN74LVC3G07DCUR matches temperature range but increases board area and quiescent current - making the original the optimal balance for 5 V industrial I/O buffering.

FAQ
Can 74HCT3G07DC,125 drive a 10 kΩ pull-up resistor on its open-drain output?
Yes - with VCC = 5.0 V and IO = 0.5 mA, VOL remains ≤0.15 V (per datasheet Table 7), well within logic LOW threshold for downstream 5 V CMOS inputs. The output can sink up to 4.0 mA while holding VOL ≤0.4 V, supporting pull-up values from 1.2 kΩ (4 mA) to 10 kΩ (0.5 mA) depending on rise-time requirements.
Is external clamping required when connecting 12 V signals to the inputs?
No - internal input clamp diodes allow direct connection of voltages up to VCC + 0.5 V (i.e., ≤6.0 V at 5.5 V supply). For 12 V signals, a series current-limiting resistor (e.g., 10 kΩ) must be used to restrict IIK to ±20 mA maximum, as specified in Absolute Maximum Ratings (Table 5).
Does this device support hot-swap or live-insertion?
No - the datasheet does not specify hot-swap capability. Power sequencing requirements mandate VCC applied before input signals; applying inputs prior to VCC risks latch-up or excessive clamp current. Use power-good monitoring or sequenced supply rails in hot-plug systems.
What is the maximum capacitive load the output can drive while maintaining 400 kHz I²C timing?
At 400 kHz, total bus capacitance must stay ≤400 pF per I²C specification. With typical CL = 30 pF (PCB + connector) and 4.7 kΩ pull-up, the 74HCT3G07DC,125's 1.5 pF input capacitance and low VOL ensure rise time <1 μs - verified in dynamic characteristics (Table 8) for loads ≤300 pF at 5 V, meeting timing margins with margin.
