Product details
Overview
MC74VHC1G01DTT1G from onsemi is a single 2-input NAND gate with open-drain output, designed for level-shifting and wired-AND logic in mixed-voltage systems. It operates from 2.0 V to 5.5 V, 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 reliable interfacing between 3 V and 5 V circuits in industrial control I/O modules.
For engineers reviewing the MC74VHC1G01DTT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain output compatibility with pull-up networks, IOFF partial power-down protection for hot-swap systems, and AEC-Q100 qualification for automotive body electronics where supply voltage mismatches occur.
Technical Context
This device implements standard CMOS NAND logic with TTL-compatible input thresholds (VIH = 1.5 V min at VCC = 2.0 V), enabling direct connection to legacy 5 V logic while powered from 3.3 V rails. Its open-drain output allows bidirectional bus arbitration and wired-AND configuration without external diodes.
The input and output structures tolerate voltages up to 5.5 V independent of VCC, supporting safe operation during battery backup transitions and hot insertion. IOFF circuitry ensures high-impedance outputs when VCC = 0 V, preventing back-powering of inactive supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-rail interface designs across 3.3 V and 5 V subsystems |
| tPD (typ) | 3.5 ns at 5 V - enables timing-critical signal conditioning in high-speed digital control loops |
| IOL (max) | 8 mA at 3.0 V - drives standard LED indicators or small MOSFET gates directly |
| VIN/VOUT Tolerance | Up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interfaces |
| IOFF Support | Active at VCC = 0 V - prevents current leakage during partial power-down in modular systems |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments |
| Package | SC-74A (SOT-23-5) - compact 3.0 mm × 1.5 mm footprint for space-constrained PCB layouts |
Pinout & Package
MC74VHC1G01DTT1G is housed in the SC-74A (SOT-23-5) package - a 3.0 mm × 1.5 mm surface-mount outline with 0.95 mm height and 0.95 mm lead pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second NAND input - accepts 0–5.5 V logic signals independent of VCC |
| 2 | A | First NAND input - CMOS-level threshold (VIH ≥ 1.5 V @ 2.0 V VCC) |
| 3 | GND | Ground reference - must be connected before VCC to ensure proper ESD protection activation |
| 4 | Y | Open-drain output - requires external pull-up to define HIGH state; sinks up to 8 mA |
| 5 | VCC | Positive supply - powers internal logic and enables IOFF behavior when de-energized |
Key Features
| Feature | Design Value |
|---|---|
| Over-Voltage Tolerant I/O | Inputs and outputs withstand 5.5 V even at VCC = 2.0 V - enables robust 5 V-to-3.3 V level translation without external components |
| IOFF Partial Power-Down | Outputs enter high-impedance state when VCC = 0 V - prevents backfeeding into powered subsystems during hot-swap events |
| Open-Drain Output | Supports wired-AND bus architectures and I²C-compatible signaling - eliminates contention in shared-line applications |
| AEC-Q100 Qualified | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP capability - suitable for automotive body control modules and lighting drivers |
| Pb-Free & RoHS Compliant | Meets J-STD-609 Category 1 moisture sensitivity (MSL 1) - supports standard reflow profiles without baking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G01DBVR | 3.3 V only VCC range (1.65–5.5 V), lower 3.2 ns tPD at 3.3 V, no AEC-Q100 qualification | Lacks automotive qualification and extended −55 °C low-temp support; optimized for consumer-grade portable systems | Select when cost-sensitive non-automotive designs require faster switching and tighter VOL specs at 3.3 V only. |
| 74AUP1G01GW,125 | Ultra-low power (0.9 μA ICC), wider −40 °C to +125 °C range, but only 1.8–3.6 V VCC operation | Not suitable for 5 V interface applications; better for battery-powered IoT nodes requiring minimal quiescent current | Choose for energy-constrained edge sensors where 5 V tolerance is unnecessary and sub-1 μA sleep current is critical. |
Compared with SN74LVC1G01DBVR and 74AUP1G01GW,125, MC74VHC1G01DTT1G uniquely combines 5.5 V I/O tolerance, AEC-Q100 Grade 1 qualification, and full −55 °C operation - making it the only option among the three validated for under-hood automotive and wide-temperature industrial control use cases.
