Product details
Overview
MC74VHC1G00DBVT1G from onsemi is a single 2-input NAND gate in SC-74A (SOT-25) package, designed for 2.0 V to 5.5 V operation with CMOS-level input thresholds. It delivers 3.5 ns typical propagation delay at 5 V, supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-supply interfacing in portable logic and level-shifting applications.
For engineers reviewing the MC74VHC1G00DBVT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC-74A footprint compatibility, IOFF partial power-down support, ±25 mA output current capability, and guaranteed operation across −55 °C to +125 °C industrial temperature range.
Technical Context
This device implements standard positive-logic NAND functionality (Y = NOT(A AND B)) using advanced VHC CMOS process technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe interfacing between 5 V legacy circuits and 3 V microcontrollers without external level shifters.
The output stage provides symmetrical sourcing/sinking capability (8 mA at 3.0 V), and IOFF circuitry ensures high-impedance outputs during power-down, preventing back-driving of powered rails in partial-power-down systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports direct integration into both 3.3 V and 5 V logic domains without voltage translation. |
| tPD (Typ) | 3.5 ns at 5 V - enables high-speed signal conditioning in timing-critical control paths. |
| IOH/IOL | ±8 mA at 3.0 V - sufficient to drive multiple 74-series TTL inputs or small LED indicators directly. |
| Input Voltage Tolerance | −0.5 V to +5.5 V - eliminates need for external clamping diodes when interfacing to higher-voltage sources. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor equipment use. |
| IOFF Support | Active at VCC = 0 V - prevents current leakage and bus contention during hot-swap or partial system shutdown. |
| ESD Rating | 2000 V HBM - enhances reliability in manual handling and board assembly environments. |
Pinout & Package
MC74VHC1G00DBVT1G is housed in SC-74A (SOT-25) package - a 5-pin, 3.0 mm × 1.5 mm surface-mount outline with 0.95 mm height and 0.95 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A | First NAND operand; accepts CMOS-level logic signals (VIH ≥ 1.5 V @ 2.0 V VCC). |
| 2 | GND | Ground reference for all internal circuitry and I/O; must be connected to system ground plane. |
| 3 | Input B | Second NAND operand; electrically identical to Pin 1 with same input threshold behavior. |
| 4 | Output Y | NAND result (Y = NOT(A AND B)); actively drives high/low with 8 mA capability at 3 V. |
| 5 | VCC | Positive supply rail; powers internal logic and defines output voltage swing (VOH/VOL). |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand up to 5.5 V regardless of VCC - enables safe 5 V-to-3 V interface without external protection components. |
| IOFF Partial Power-Down | Outputs enter high-impedance state when VCC = 0 V - prevents back-current flow and bus conflicts during system sleep or hot-insertion. |
| Wide Supply Range | Operates from 2.0 V to 5.5 V - simplifies design reuse across battery-powered (2.5–3.3 V) and legacy 5 V systems. |
| Low Propagation Delay | 3.5 ns typical tPD at 5 V - meets timing requirements for clock gating, enable control, and fast status decoding. |
| Pb-Free & RoHS Compliant | Meets J-STD-609 Category 1 moisture sensitivity and UL 94 V-0 flammability - suitable for lead-free reflow and regulated end markets. |
Applications
| Industrial Sensor Interface | Portable Device Power Control |
|---|---|
Use Scenario: Interfacing 5 V analog sensor output enable lines to a 3.3 V microcontroller GPIO with shared power domain. IC Role / Device Role / Timing Role: Level-shifting NAND gate performing active-low enable inversion and voltage domain isolation. Use Value: Eliminates discrete resistor-divider or dedicated level shifter IC, reducing BOM count and PCB area while maintaining noise margin. | Use Scenario: Controlling power-on sequencing of dual-rail subsystems (e.g., RF transceiver + baseband processor) in handheld medical monitors. IC Role / Device Role / Timing Role: Logic combiner ensuring both enable signals are asserted before releasing main power rail. Use Value: Provides deterministic startup order with sub-10 ns timing resolution and zero additional quiescent current (<1 μA ICC). |
| Automotive Body Control Module | IoT Edge Node Status Monitoring |

IC Role / Device Role / Timing Role: Active-low alarm aggregator asserting single "system error" signal when any sensor fails. Use Value: Reduces MCU GPIO usage by 2 pins; operates reliably at 1.8 V sleep voltage due to wide VCC range and low ICC (≤40 μA max). |
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), slightly slower tPD (4.5 ns typ @ 3.3 V), same SC-74A package. | Better suited for ultra-low-voltage 1.8 V systems; less margin for 2.0 V brown-out conditions. | Select when operating below 2.0 V or requiring TI's enhanced latch-up immunity. |
| 74AUP1G00GW,125 | Ultra-low power (ICC ≤ 0.9 μA), slower speed (tPD = 10.3 ns @ 3.3 V), same pinout but different marking orientation. | Optimized for battery life over speed; not recommended for >1 MHz toggle rates. | Select for energy-constrained IoT nodes where static power dominates total consumption. |
Compared with SN74LVC1G00DBVR and 74AUP1G00GW,125, MC74VHC1G00DBVT1G offers superior speed-to-power ratio above 2.5 V and broader over-voltage tolerance - making it optimal for mixed-voltage industrial interfaces where robustness and timing precision are jointly critical.

FAQ
What is the maximum input voltage rating for MC74VHC1G00DBVT1G?
The MC74VHC1G00DBVT1G supports DC input voltages from −0.5 V to +5.5 V, independent of VCC. This over-voltage tolerance allows safe connection to 5 V signals even when powered from 3.3 V or 2.5 V supplies - a key feature for mixed-voltage system interfacing without external protection components. The rating is validated per Absolute Maximum Ratings table in the official onsemi datasheet Rev. 29.
Does MC74VHC1G00DBVT1G support partial power-down operation?
Yes, MC74VHC1G00DBVT1G includes IOFF circuitry that places outputs in high-impedance state when VCC = 0 V. This prevents back-driving of powered buses during hot insertion or partial system shutdown. The feature is explicitly documented in the datasheet Features section and verified under DC Electrical Characteristics for IOFF leakage current (≤10 μA at 0 V VCC).
What is the propagation delay of MC74VHC1G00DBVT1G at 3.3 V supply?
At VCC = 3.3 V, MC74VHC1G00DBVT1G exhibits typical propagation delay (tPLH/tPHL) of 4.5 ns with CL = 15 pF, and 5.6 ns with CL = 50 pF, per AC Electrical Characteristics table in the datasheet. These values are measured under −40 °C to +85 °C conditions and confirm suitability for sub-100 MHz digital control paths.
Which package type does MC74VHC1G00DBVT1G use?
MC74VHC1G00DBVT1G uses the SC-74A (also known as SOT-25) package - a 5-pin, 3.0 mm × 1.5 mm surface-mount outline with 0.95 mm pitch and 0.95 mm height. This is confirmed in the Ordering Information table (page 7) and Mechanical Case Outline drawing (CASE 318BQ) of the official onsemi datasheet.
Is MC74VHC1G00DBVT1G compatible with 5 V TTL input levels?
No - MC74VHC1G00DBVT1G has CMOS-level input thresholds (VIH ≥ 1.5 V @ 2.0 V, ≥ 2.1 V @ 3.0 V), unlike the MC74VHC1GT00 variant which is optimized for TTL-level inputs. For TTL-compatible operation, MC74VHC1GT00DBVT1G is the designated variant, as clearly differentiated in the datasheet's first paragraph and DC Electrical Characteristics tables.
