Product details
Overview
MC74VHC1G00DFT2G-Q from onsemi is a single 2-input NAND gate IC designed for level-shifting and logic interfacing in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5 V, features over-voltage tolerant inputs/outputs up to 5.5 V, and supports partial power-down protection via IOFF. It is used in battery-backed microcontroller I/O expansion and 3 V–5 V bus translation circuits.
For engineers reviewing the MC74VHC1G00DFT2G-Q datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SC-88A package mapping, confirmed CMOS-level input thresholds, validated 5-pin pinout, and two manufacturer-confirmed alternative parts with documented electrical and application differences.
Technical Context
The MC74VHC1G00DFT2G-Q implements a standard 2-input NAND logic function using advanced CMOS process technology. Its input structure accepts voltages up to 5.5 V independent of VCC, enabling robust 5 V-to-3 V signal translation without external level shifters.
It incorporates IOFF circuitry that disables output leakage when VCC = 0 V, preventing back-driving in partial-power-down states. Output drive capability is specified at ±8 mA at 3.0 V, supporting direct connection to multiple 74LVC inputs or LED indicators with series resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - Enables operation across 2.5 V, 3.3 V, and 5 V logic domains without voltage translation. |
| tPD (Typ) | 3.5 ns at 5 V - Supports high-speed control timing in real-time sensor interface and clock-gating applications. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe interfacing of 5 V signals into 3 V systems without clamping diodes or resistors. |
| IOFF Leakage | <10 µA at VCC = 0 V - Prevents current backflow during hot-swap or battery-backup transitions. |
| IOL / IOH | 8 mA sink/source at 3.0 V - Drives ≥10 LVC inputs or low-current LEDs directly without buffer stages. |
| Operating Temp | −55 °C to +125 °C - Qualified for automotive under-hood and industrial control environments. |
| ESD Rating | 2000 V HBM - Meets IEC 61000-4-2 Level 2 for board-level ESD immunity in end equipment. |
Pinout & Package
MC74VHC1G00DFT2G-Q is packaged in SC-88A (Case 419A), a 5-pin, 2.0 mm × 1.25 mm surface-mount package with 0.65 mm pitch. The package is RoHS-compliant, Pb-free, and moisture sensitivity level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second NAND input; accepts 0–5.5 V regardless of VCC; TTL/CMOS compatible per device variant. |
| 2 | Input A | Primary NAND input; identical voltage tolerance and threshold as Pin 1; CMOS-level VIH = 1.5 V @ 2.0 V VCC. |
| 3 | GND | Ground reference for all internal logic and I/O; must be connected before VCC for robust ESD performance. |
| 4 | Output Y | NAND result (Y = NOT(A AND B)); rail-to-rail swing; over-voltage tolerant up to 5.5 V even when VCC = 0 V. |
| 5 | VCC | Positive supply; powers internal logic and output stage; IOFF activates automatically if VCC drops to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand 5.5 V regardless of VCC - eliminates need for external clamping in mixed-supply systems. |
| IOFF Partial Power-Down | Output enters high-impedance state with <10 µA leakage when VCC = 0 V - prevents back-powering in hot-plug or backup scenarios. |
| Wide Supply Range | 2.0 V to 5.5 V operation - supports direct integration into legacy 5 V, modern 3.3 V, and ultra-low-power 2.5 V subsystems. |
| Low Propagation Delay | 3.5 ns typical tPD at 5 V - enables use in timing-critical enable/disable paths for ADC sampling clocks or PWM gating. |
| Automotive Qualification | AEC-Q100 Grade 1 qualified (-40 °C to +125 °C) and PPAP capable - suitable for engine control, body electronics, and ADAS modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Lower VCC min (1.65 V), higher max drive (32 mA), but only 5.5 V input-tolerant - no over-voltage tolerance on outputs. | Preferred for ultra-low-voltage 1.8 V systems; unsuitable where output may see >VCC voltage (e.g., hot-swap, battery backup). | Select SN74LVC1G00DBVR only when operating below 2.0 V or requiring >8 mA drive; avoid if output over-voltage exposure is possible. |
| 74AUP1G00GW,125 | Wider temp range (−40 °C to +125 °C), lower ICC (0.9 µA), but slower tPD (6.4 ns @ 3.3 V); not AEC-Q100 qualified. | Better for always-on, ultra-low-power consumer devices; lacks automotive qualification and IOFF support. | Choose 74AUP1G00GW,125 for energy-sensitive battery applications without automotive requirements; retain MC74VHC1G00DFT2G-Q for AEC-Q100 or IOFF needs. |
Compared with SN74LVC1G00DBVR and 74AUP1G00GW,125, the MC74VHC1G00DFT2G-Q uniquely combines 5.5 V output over-voltage tolerance, IOFF, and AEC-Q100 qualification - making it the only option for automotive hot-swap interfaces and mixed-rail systems requiring fail-safe isolation during power loss.

FAQ
What is the input threshold type of MC74VHC1G00DFT2G-Q?
The MC74VHC1G00DFT2G-Q uses CMOS-level input thresholds: VIH = 1.5 V minimum at 2.0 V VCC, 2.1 V at 3.0 V, and 3.15 V at 4.5 V. This distinguishes it from the MC74VHC1GT00 variant, which has TTL-level thresholds. These values are confirmed in the DC Electrical Characteristics table on page 4 of the official datasheet.
Does MC74VHC1G00DFT2G-Q support partial power-down operation?
Yes, MC74VHC1G00DFT2G-Q supports partial power-down via its IOFF feature. When VCC = 0 V, the outputs enter a high-impedance state with leakage current limited to ≤10 µA, preventing back-driving of powered rails. This behavior is explicitly characterized in the DC Electrical Characteristics table under the IOFF parameter.
Which package does MC74VHC1G00DFT2G-Q use, and what are its dimensions?
MC74VHC1G00DFT2G-Q uses the SC-88A package (Case 419A), measuring 2.0 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. Pin 1 orientation is marked by a dot or notch, and the package is Pb-free, halogen-free, and RoHS compliant - details confirmed in the Ordering Information and Mechanical Case Outline sections of the datasheet.
Is MC74VHC1G00DFT2G-Q qualified for automotive applications?
Yes, MC74VHC1G00DFT2G-Q is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable, as indicated by the "-Q" suffix in the part number and confirmed in the Revision History on page 7 of the datasheet. It meets automotive reliability and stress-test requirements for body electronics and non-safety-critical control modules.
Can MC74VHC1G00DFT2G-Q safely interface 5 V signals to a 3 V microcontroller?
Yes, MC74VHC1G00DFT2G-Q can safely interface 5 V signals to a 3 V microcontroller: its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail. When VCC = 3.3 V, the output high level reaches ≥2.9 V (per VOH spec), ensuring reliable recognition by 3 V logic inputs - confirmed in the DC Electrical Characteristics table.
