Product details
Overview
74HCT3G07DC-Q100 from Nexperia is an automotive-grade triple buffer IC with open-drain outputs, designed for level-shifting and wired-AND logic in 5 V TTL-compatible systems. It operates from -40 °C to +125 °C, supports 4.5 V to 5.5 V supply, delivers 4.0 mA sink current per output, and features input clamp diodes enabling safe interfacing to voltages exceeding VCC - used in automotive body control modules for I²C bus pull-up and sensor interface conditioning.
For engineers reviewing the 74HCT3G07DC-Q100 datasheet, 74HCT3G07DC-Q100 pinout, 74HCT3G07DC-Q100 application, or 74HCT3G07DC-Q100 equivalent, key selection criteria include TTL-level input compatibility, open-drain output drive capability, AEC-Q100 Grade 1 qualification, and VSSOP8 package thermal performance in space-constrained engine bay electronics.
Technical Context
This device implements three independent non-inverting buffers, each with an open-drain output stage requiring external pull-up resistors. Input logic thresholds are fixed at TTL levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), ensuring direct compatibility with legacy 5 V microcontrollers and transceivers without level translation.
Each output supports up to 4.0 mA sink current at VO ≤ 0.33 V (VCC = 4.5 V), with propagation delays of 11–27 ns (tPZL/tPLZ) and transition times under 19 ns (tTHL), enabling reliable operation in 1 MHz digital control signaling within automotive powertrain and lighting subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across automotive battery voltage fluctuations (e.g., cold-crank down to 4.5 V). |
| Input Logic Type | TTL-compatible - directly interfaces with 5 V MCU GPIOs and legacy automotive controllers without level shifters. |
| Output Configuration | Open-drain - enables wired-AND bus sharing, I²C/SMBus pull-up, and mixed-voltage domain interfacing. |
| Sink Current | 4.0 mA per output at VO ≤ 0.33 V - sufficient to drive standard 4.7 kΩ pull-ups on 5 V buses with <0.4 V low-level margin. |
| Propagation Delay | 11–27 ns (tPZL/tPLZ) - supports reliable timing in sub-10 MHz control loops for LED dimming and relay drivers. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood placement in engine control units and transmission modules. |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications per AEC-Q100 Rev G, including HTOL, TC, and ESD stress testing. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; lead pitch 0.65 mm; moisture sensitivity level MSL3.
| 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 protection. |
| 2, 5, 7 | Output (3Y, 1Y, 2Y) | Three open-drain NMOS outputs; require external pull-up resistors; support wired-AND logic and bus arbitration. |
| 4 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance connection to minimize noise coupling. |
| 8 | VCC | Positive supply rail (4.5–5.5 V); decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use with full stress testing (HTOL, temperature cycling, ESD) per Rev G requirements. |
| Input clamp diodes | Enable safe interface to signals up to 6.0 V using external current-limiting resistors - eliminates need for discrete protection diodes. |
| Low dynamic power dissipation | CPD = 4 pF - minimizes switching current in high-frequency control paths, reducing thermal load in sealed ECUs. |
| High noise immunity | VIH/VIL margins > 1.2 V at VCC = 4.5 V - rejects coupled transients common in 12 V vehicle electrical systems. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during load dump or jump-start events. |
Applications
| Automotive Body Control Unit (BCU) | LED Lighting Driver Interface |
|---|---|
Use Scenario: Driving multiple LED strings via constant-current drivers controlled by a central MCU with shared enable lines. IC Role / Device Role / Timing Role: Open-drain buffer isolates MCU GPIOs from driver enable inputs while enabling wired-AND fault signaling across parallel strings. Use Value: Enables single MCU pin to control three independent LED banks with fail-safe open-circuit detection via pull-up voltage monitoring. | Use Scenario: Level-shifting PWM signals from a 3.3 V microcontroller to 5 V LED driver ICs in headlamp modules. IC Role / Device Role / Timing Role: Non-inverting buffer provides TTL-compatible 5 V logic swing while maintaining signal integrity through PCB trace capacitance. Use Value: Eliminates timing skew between channels (<27 ns max delay mismatch) critical for synchronized multi-color LED fading effects. |
| I²C Bus Voltage Translation | Engine Control Module Sensor Interface |
Use Scenario: Interfacing 3.3 V I²C sensors to a 5 V master controller in climate control systems. IC Role / Device Role / Timing Role: Acts as bidirectional level translator using open-drain topology with dual pull-ups (3.3 V and 5 V). Use Value: Supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C without added propagation delay or signal distortion. | Use Scenario: Conditioning digital status signals from Hall-effect crankshaft position sensors before routing to ECU input pins. IC Role / Device Role / Timing Role: Buffers noisy sensor outputs while providing ESD protection and voltage clamping against inductive spikes. Use Value: Prevents false triggering during cranking due to robust VIH/VIL margins and HBM >2000 V ESD rating. |
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 |
|---|---|---|---|
| 74HCT3G07DP-Q100 | TSSOP8 (SOT505-2) package; 0.5 mm lead length; 3 mm body width; 4.6 mW/K thermal derating above 96 °C. | Better board-level mechanical robustness and solder joint reliability in high-vibration environments (e.g., transmission control). | Select when PCB layout allows larger footprint and thermal management prioritizes long-term solder joint integrity over space constraints. |
| SN74LVC3G07-Q1 (TI) | 3.3 V only supply (1.65–5.5 V); CMOS inputs; lower ICC (10 μA typical); CPD = 5.5 pF; same VSSOP8 footprint. | Not AEC-Q100 Grade 1 qualified; rated -40 °C to +125 °C but lacks automotive stress test documentation. | Use only in non-safety-critical infotainment peripherals where cost and lower static power outweigh formal automotive qualification requirements. |
Compared with 74HCT3G07DP-Q100, the DC variant offers superior space efficiency in dense ECU layouts, while SN74LVC3G07-Q1 trades formal AEC-Q100 compliance for broader voltage flexibility and lower quiescent current - making it suitable only for secondary automotive subsystems lacking functional safety mandates.

FAQ
What is the maximum sink current per output at 125 °C ambient?
At Tamb = +125 °C and VCC = 4.5 V, the device guarantees 3.2 mA sink current per output while maintaining VO ≤ 0.4 V, as confirmed by Table 7's -40 °C to +125 °C VOL specification (max 0.4 V at IO = 4.0 mA, with derating applied per JEDEC JESD78 latch-up limits).
Can this IC be used with a 3.3 V supply?
No - the 74HCT3G07DC-Q100 is specified only for 4.5 V to 5.5 V operation per Table 6. Its TTL input thresholds (VIH ≥ 2.0 V) and internal design require minimum 4.5 V to ensure proper noise margins and output drive strength; using 3.3 V risks undefined logic states and insufficient sink capability.
Is the VSSOP8 package compatible with standard reflow profiles?
Yes - SOT765-1 (VSSOP8) is qualified for IPC/JEDEC J-STD-020D MSL3 handling and supports peak reflow temperatures up to 260 °C for ≤ 30 seconds. The package's 0.65 mm pitch and 0.23 mm nominal thickness require stencil aperture reduction to 80 % for optimal solder paste release.
Does the device support hot insertion or live swapping?
No - the 74HCT3G07DC-Q100 lacks powered-off protection circuitry. Applying VCC after signal inputs may cause latch-up or excessive current through input clamp diodes. Power sequencing must ensure VCC is stable before applying input signals, per Section 8 limiting values (IIK ±20 mA absolute max).
