Product details
Overview
MC74VHC1G01DBVT1G from onsemi is a single 2-input NAND gate with open-drain output in SC-74A (SOT-23-5) package, designed for level-shifting and wired-OR logic applications across 2.0 V to 5.5 V supply rails. It features CMOS-level input thresholds, 3.5 ns typical propagation delay at 5 V, ±8 mA output drive at 3.0 V, and over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-signal interfacing in automotive and industrial control systems.
For engineers reviewing the MC74VHC1G01DBVT1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, validated SC-74A pin mapping, AEC-Q100 qualified automotive use context, IOFF partial power-down support, and real-world interface design guidance - all grounded in the official onsemi Rev. 22 datasheet.
Technical Context
The MC74VHC1G01DBVT1G implements a standard 2-input NAND logic function with open-drain output architecture, requiring an external pull-up resistor for high-level assertion. Its input structure tolerates voltages up to 5.5 V independent of VCC, supporting bidirectional voltage translation between 3 V and 5 V domains without level-shifters.
IOFF circuitry disables input/output leakage when VCC = 0 V, preventing back-powering and enabling hot-insertion safety in modular systems. The device operates across −55 °C to +125 °C and meets AEC-Q100 Grade 1 requirements when ordered with the −Q suffix, as confirmed by the ordering table and qualification note in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports single-supply operation across 3 V and 5 V logic families without level conversion. |
| tPD (typ) | 3.5 ns at VCC = 5 V, CL = 15 pF - enables high-speed signal conditioning in timing-critical control paths. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - allows safe connection to 5 V signals while powered from 3 V, eliminating risk of latch-up or damage. |
| IOL (max) | 8 mA at VCC = 3.0 V - sufficient to drive LEDs, small MOSFET gates, or multiple CMOS inputs in low-power systems. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - ensures no back-current flow during power sequencing or partial shutdown. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor embedded applications. |
| ESD Rating | HBM: 2000 V - provides robust handling protection during PCB assembly and field service. |
Pinout & Package
MC74VHC1G01DBVT1G is housed in the SC-74A (SOT-23-5) package - a 3.0 mm × 1.5 mm × 0.95 mm surface-mount outline with 0.95 mm lead pitch, optimized for space-constrained PCB layouts in automotive modules and portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second NAND input - accepts CMOS-level logic signals; tolerant to 5.5 V regardless of VCC. |
| 2 | A | First NAND input - identical electrical behavior to Pin 1; both inputs share over-voltage protection. |
| 3 | GND | Ground reference - must be connected to system ground plane; serves as return path for IOL current. |
| 4 | Y | Open-drain output - sinks current only; requires external pull-up to define high state voltage and logic level. |
| 5 | VCC | Positive supply - powers internal logic; IOFF activation occurs automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| CMOS-level input thresholds | VIH = 1.5 V (min) at VCC = 2.0 V - ensures reliable recognition of 3 V logic highs without false triggering. |
| Over-voltage tolerant I/O | Inputs and outputs withstand 5.5 V even at VCC = 2.0 V - eliminates need for external clamping diodes in mixed-voltage designs. |
| IOFF partial power-down | Blocks >99% of input/output leakage when VCC = 0 V - prevents unintended power injection into unpowered subsystems. |
| Open-drain output architecture | Enables wired-OR bus configurations and flexible pull-up selection - supports I²C-compatible signaling and multi-master arbitration. |
| AEC-Q100 qualified (−Q option) | MC74VHC1G01DBVT1G−Q* variant meets Grade 1 stress testing - certified for automotive body electronics and ADAS sensor interfaces. |
Applications

Use Value: Eliminates discrete level-shifter ICs; leverages inherent 5.5 V input tolerance and open-drain output to safely drive 5 V loads from 3 V domain. |
Use Scenario: Implementing shared interrupt line across three 3.3 V peripherals in an industrial PLC module. IC Role / Device Role / Timing Role: Wired-OR combiner - each peripheral drives its own MC74VHC1G01DBVT1G output low to assert shared INT# signal. Use Value: Provides clean, glitch-free interrupt aggregation with minimal board area; open-drain outputs prevent contention and simplify routing. |
| Hot-Swappable Module Detection | Power Sequencing Monitor |
|
Use Scenario: Detecting insertion/removal of a daughterboard in a telecom base station backplane. IC Role / Device Role / Timing Role: Presence detector - daughterboard pulls one input low; MC74VHC1G01DBVT1G output asserts interrupt when board is seated. Use Value: IOFF protection prevents back-powering of unpowered daughterboard; over-voltage tolerance handles transient coupling during mating. |
Use Scenario: Monitoring power-good status of a 12 V DC-DC converter feeding a 3.3 V LDO in a motor drive controller. IC Role / Device Role / Timing Role: Power sequencing logic element - NAND gate combines enable and PG signals to gate downstream reset generation. Use Value: Ensures deterministic startup order; wide VCC range allows direct monitoring of both 12 V and 3.3 V rails via resistive dividers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate with open-drain output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G01DBVR | TTL-compatible inputs (VIH = 2.0 V min at 3.3 V), slightly higher ICC (max 10 µA vs 40 µA), same SC-70-5 package. | Better suited for 3.3 V-only systems where TTL input compatibility is required; lacks 5.5 V over-voltage tolerance. | Select when interfacing legacy 3.3 V TTL logic and full 5 V tolerance is unnecessary. |
| 74AUP1G01GW,125 | Lower VCC range (0.8 V–3.6 V), ultra-low power (ICC < 0.9 µA), smaller XSON-6 package - not pin-compatible. | Targeted at battery-powered IoT sensors; incompatible with 5 V domains and SC-74A footprint. | Choose for sub-1 V to 3.6 V ultra-low-power applications where board space and quiescent current dominate. |
Compared with SN74LVC1G01DBVR and 74AUP1G01GW,125, the MC74VHC1G01DBVT1G uniquely supports 2.0–5.5 V operation with 5.5 V I/O tolerance and AEC-Q100 qualification - making it the only choice for automotive-grade 3 V/5 V mixed-signal interfacing in a standard SOT-23-5 layout.

FAQ
What is the maximum input voltage rating for MC74VHC1G01DBVT1G?
The MC74VHC1G01DBVT1G supports DC input voltages from −0.5 V to +5.5 V, independent of VCC level. This over-voltage tolerance allows safe connection to 5 V signals even when powered from 2.0 V or 3.3 V supplies - a key enabler for mixed-voltage system design without external protection components. The absolute maximum rating is documented in the "Maximum Ratings" table on page 3 of the onsemi datasheet Rev. 22.
Does MC74VHC1G01DBVT1G support partial power-down functionality?
Yes, MC74VHC1G01DBVT1G includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This feature limits power-off leakage current to ≤10 µA, preventing back-powering of unpowered sections in modular systems. It is explicitly verified in the "DC Electrical Characteristics" table on page 4 of the datasheet and applies to both input pins and the open-drain output Y.
What package type does MC74VHC1G01DBVT1G use, and is it RoHS compliant?
MC74VHC1G01DBVT1G uses the SC-74A (SOT-23-5) package - a 3.0 mm × 1.5 mm × 0.95 mm surface-mount outline with 0.95 mm lead pitch. Per the datasheet's "Features" section and ordering information, this device is Pb-free, halogen-free/BFR-free, and fully RoHS compliant. The "G" suffix in the part number confirms lead-free packaging per JEDEC J-STD-609.
Is MC74VHC1G01DBVT1G qualified for automotive applications?
Yes - the MC74VHC1G01DBVT1G−Q* variant is AEC-Q100 qualified and PPAP capable, meeting Grade 1 temperature requirements (−40 °C to +125 °C ambient). The datasheet explicitly states this qualification in the "Features" list and "Ordering Information" table. Standard MC74VHC1G01DBVT1G (without −Q) shares identical silicon and package but lacks automotive-specific process controls and documentation.
Can MC74VHC1G01DBVT1G drive an LED directly?
Yes, MC74VHC1G01DBVT1G can drive an LED directly when configured as a low-side switch: connect the LED anode to VCC (2.0–5.5 V), cathode to Y (Pin 4), and rely on the open-drain output to sink current. At 3.0 V VCC, it delivers ≥8 mA - sufficient for indicator LEDs. Ensure series resistance limits current to ≤25 mA (absolute max) and respects VOL spec (≤0.52 V at 8 mA, 5.5 V).
