Product details
Overview
MC74VHC1G07DFT2 from onsemi is a single non-inverting buffer IC with open-drain output, CMOS-level input thresholds, 2.0–5.5 V supply operation, 3.5 ns typical propagation delay at 5 V, and overvoltage-tolerant I/O up to 5.5 V-used for level-shifting between 3 V and 5 V logic domains in industrial control interfaces.
For engineers reviewing the MC74VHC1G07DFT2 datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive capability (8 mA sink at 3.0 V), IOFF partial power-down protection, −55 °C to +125 °C operating range, and AEC-Q100 qualification for automotive subsystems.
Technical Context
This device implements a single-channel non-inverting buffer with open-drain output stage, enabling wired-OR logic and bidirectional bus interfacing. Its input structure tolerates voltages up to 5.5 V independent of VCC, supporting mixed-voltage system interconnects without external clamping.
The IC features IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering of powered-down rails. It operates across 2.0–5.5 V with guaranteed VIH/VIL thresholds matching standard CMOS logic families and supports hot insertion in live systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct use in both 3.3 V and 5 V systems without level translators |
| tPD (Typ) | 3.5 ns at 5 V - supports high-speed digital interface timing in real-time control loops |
| IOL (Max) | 8 mA at 3.0 V - sufficient to drive LED indicators or pull-down loads in sensor interface circuits |
| VIH/VIL | CMOS-compatible thresholds (e.g., VIH = 3.15 V min at VCC = 4.5 V) - ensures clean logic recognition across voltage rails |
| IOFF Leakage | <10 µA at VCC = 0 V - prevents unintended current paths during partial power-down states |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments |
| ESD Rating | 2000 V HBM - provides robust handling during board assembly and field service |
Pinout & Package
MC74VHC1G07DFT2 is packaged in SC-88A (SOT-353), a 5-pin surface-mount package measuring 2.1 mm × 1.25 mm × 0.95 mm with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must be left floating or tied to GND for mechanical stability only |
| 2 | Input (A) | CMOS-level buffered input - accepts 0–5.5 V signals regardless of VCC value |
| 3 | GND | Ground reference for all internal circuitry and output stage - requires low-impedance PCB connection |
| 4 | Output (Y) | Open-drain output - requires external pull-up resistor to define high state; sinks up to 8 mA at 3.0 V |
| 5 | VCC | Positive supply rail - powers internal logic and defines output high-level threshold for pull-up network |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant I/O | Inputs and outputs withstand up to 5.5 V even when VCC = 0 V - eliminates need for external clamping diodes in mixed-rail systems |
| IOFF Partial Power-Down | Input/output leakage remains <10 µA when VCC = 0 V - prevents back-driving of powered-down subsystems |
| Wide Supply Range | Operates from 2.0 V to 5.5 V - supports battery-powered, 3.3 V microcontroller, and legacy 5 V peripheral interfaces |
| AEC-Q100 Qualified | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP capability - suitable for automotive body electronics and infotainment modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Lower VCC min (1.65 V), higher IOL (24 mA at 3.3 V), no AEC-Q100 qualification | Better suited for ultra-low-voltage portable designs but lacks automotive reliability validation | Select when operating below 2.0 V or requiring >12 mA sink current; avoid for automotive Grade 1 deployments |
| 74AUP1G07GW,125 | NXP part with 0.8–3.6 V range, 3.7 ns tPD at 3.3 V, lower ICC (0.9 µA typ), no 5.5 V I/O tolerance | Optimized for battery life in IoT endpoints but cannot interface directly to 5 V buses | Prefer for energy-constrained 3.3 V-only systems; not viable for mixed 3.3/5 V interconnects |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the MC74VHC1G07DFT2 uniquely combines 5.5 V I/O tolerance, AEC-Q100 qualification, and 2.0–5.5 V operation - making it the only choice for robust 3.3/5 V bridging in automotive and industrial environments where voltage mismatch and thermal stress are design constraints.

FAQ
What is the function of the NC pin on MC74VHC1G07DFT2?
The NC (No Connect) pin on MC74VHC1G07DFT2 is internally unconnected and serves no electrical function. It must be left floating or optionally tied to GND solely for mechanical stability during PCB assembly - connecting it to any active signal or supply rail may compromise package integrity or thermal performance. This pin does not affect the operation of MC74VHC1G07DFT2 under any condition.
Can MC74VHC1G07DFT2 interface a 5 V microcontroller output to a 3.3 V FPGA input?
Yes, MC74VHC1G07DFT2 can safely interface a 5 V microcontroller output to a 3.3 V FPGA input when configured as an open-drain buffer with a pull-up resistor to 3.3 V. Its inputs tolerate up to 5.5 V regardless of VCC, and its output stage sinks current without voltage translation limitations - ensuring correct logic levels and timing for MC74VHC1G07DFT2-based level-shifting circuits.
Does MC74VHC1G07DFT2 support partial power-down operation?
Yes, MC74VHC1G07DFT2 supports partial power-down via its IOFF feature: when VCC = 0 V, input and output leakage currents remain below 10 µA, preventing back-current flow into powered-down sections of the system. This behavior is explicitly characterized in the datasheet and applies to all operating temperatures - a critical capability for MC74VHC1G07DFT2 in modular power architectures.
What is the maximum sink current capability of MC74VHC1G07DFT2 at 3.0 V supply?
The MC74VHC1G07DFT2 delivers up to 8 mA sink current at 3.0 V supply while maintaining VOL ≤ 0.44 V (max) across −40 °C to +85 °C. This rating is validated per DC Electrical Characteristics table and supports direct driving of LEDs, optocouplers, or pull-down loads in MC74VHC1G07DFT2-based interface circuits without external amplification.
Is MC74VHC1G07DFT2 qualified for automotive applications?
Yes, MC74VHC1G07DFT2 is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable, with the "−Q" suffix indicating compliance for automotive and other applications requiring unique site and control change requirements. This qualification covers thermal cycling, humidity testing, and ESD robustness - confirming MC74VHC1G07DFT2 suitability for body electronics, lighting, and infotainment subsystems.
