Product details
Overview
MC74VHC1G03DFT2G-L22038 from onsemi is a single 2-input NOR gate with open-drain output in SC-88A (SOT-353) package, operating from 2.0 V to 5.5 V supply, delivering 3.5 ns typical propagation delay at 5 V, supporting 5 V-tolerant inputs for mixed-voltage interfacing, and used in level-shifting logic control paths in industrial I/O modules.
For engineers reviewing the MC74VHC1G03DFT2G-L22038 datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain drive capability (8 mA sink at 3.0 V), overvoltage tolerance (up to 5.5 V on inputs/outputs), IOFF partial power-down protection, and SC-88A footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements standard CMOS NOR logic with an open-drain output stage, enabling wired-AND configurations and bidirectional bus interfacing. Its input structure supports voltage translation between 3 V and 5 V domains without external components, and the IOFF feature disables current flow when VCC = 0 V - critical for hot-swap and battery-backup systems.
The logic function follows Y = NOT(A OR B), with guaranteed switching across −55 °C to +125 °C. Output leakage remains ≤ ±0.25 µA in 3-state mode at 5.5 V, and input leakage stays ≤ ±1.0 µA over full temperature range, ensuring low-power integrity in always-on monitoring circuits.
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 shifters |
| tPD (Typ) | 3.5 ns at 5 V - supports high-speed control signaling in real-time industrial sequencers |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing of 5 V sensors to 3 V microcontrollers |
| Output Sink Current | 8 mA at 3.0 V - drives LEDs, pull-up resistors, or MOSFET gates directly without buffer stages |
| IOFF Protection | Active when VCC = 0 V - prevents backfeeding and latch-up during partial power-down sequences |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive and industrial motor-control environments |
| Package | SC-88A (SOT-353), 5-pin - 2.0 × 1.25 mm footprint ideal for dense sensor node PCBs |
Pinout & Package
MC74VHC1G03DFT2G-L22038 uses the SC-88A (SOT-353) package: 5-pin, 2.0 mm × 1.25 mm × 0.95 mm body, lead pitch 0.65 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input B | Second logic input; accepts 0–5.5 V regardless of VCC setting |
| 2 | Input A | Primary logic input; electrically identical to Pin 1, supports same overvoltage tolerance |
| 3 | GND | Ground reference for logic thresholds and ESD protection network |
| 4 | Y (Open Drain) | Output node requiring external pull-up; sinks up to 8 mA at 3.0 V |
| 5 | VCC | Positive supply rail; powers internal logic and enables IOFF behavior when at 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant Inputs | Withstands 5.5 V on A/B pins even when VCC = 2.0 V - eliminates need for external clamping diodes in mixed-supply designs |
| Open-Drain Output | Enables wired-AND bus arbitration and I²C-compatible signal aggregation without contention risk |
| IOFF Partial Power-Down | Blocks current flow through A/B/Y terminals when VCC = 0 V - essential for hot-plug I/O expansion cards |
| Low Propagation Delay | 3.5 ns typical at 5 V ensures timing-critical enable/disable sequencing in motor gate drivers |
| Wide Temperature Range | −55 °C to +125 °C operation validated per JEDEC JESD22-A108 - suitable for engine control units |
Applications
| Industrial PLC Input Conditioning | Automotive Body Control Module |
|---|---|
Use Scenario: Isolating and conditioning 24 V field sensor signals into 3.3 V microcontroller GPIOs via optocoupler + resistor divider networks. IC Role / Device Role / Timing Role: NOR gate configured as active-low enable for pull-up-controlled status lines; open-drain output interfaces directly to optocoupler LED anode. Use Value: Eliminates discrete transistor level shifter; 5.5 V input tolerance accommodates transient spikes on factory floor wiring without damage. |
Use Scenario: Driving door lock actuator enable lines where multiple control sources (BCM, key fob, remote start) must arbitrate access. IC Role / Device Role / Timing Role: Wired-AND bus node implementing priority-based lock/unlock arbitration using open-drain outputs tied to common pull-up. Use Value: Prevents output contention during simultaneous command events; IOFF blocks backfeed when BCM main rail is powered down but accessory rail remains live. |
| IoT Sensor Node Wake-Up Logic | Medical Infusion Pump Safety Interlock |
Use Scenario: Combining motion detection and button press signals to wake a low-power MCU from deep sleep mode. IC Role / Device Role / Timing Role: NOR gate output pulls down MCU WAKE pin (active-low); inputs connected to PIR sensor output and tactile switch. Use Value: 3.5 ns delay ensures sub-microsecond response; 8 mA sink capability drives WAKE line directly without additional buffer. |
Use Scenario: Validating dual independent safety sensor outputs before enabling pump motor driver enable signal. IC Role / Device Role / Timing Role: NOR gate verifies both sensors are LOW (safe state); output drives opto-isolator input controlling motor gate driver EN pin. Use Value: −55 °C to +125 °C rating supports sterilization cycles and ambient temperature extremes; <100 nA leakage ensures fail-safe behavior during standby. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate with open-drain applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G03DBVR | 3.3 V only VCC range (1.65–5.5 V), lower max tPD (3.1 ns @ 3.3 V), no IOFF | Lacks partial power-down protection; unsuitable for hot-swap or battery-backed systems | Select when system operates strictly at 3.3 V and IOFF is not required |
| 74AUP1G03GW,125 | Wider VCC range (0.8–3.6 V), ultra-low ICC (0.9 µA typ), higher VOL at 8 mA load | Optimized for battery-powered wearables; insufficient drive strength for industrial loads | Select for sub-1 µA standby current in portable medical devices, not for 8 mA sink applications |
Compared with SN74LVC1G03DBVR and 74AUP1G03GW,125, MC74VHC1G03DFT2G-L22038 uniquely combines 2.0–5.5 V operation, 5.5 V overvoltage tolerance, IOFF, and 8 mA sink - making it the only choice for robust mixed-voltage industrial control nodes requiring fail-safe power sequencing.

The MC74VHC1G03DFT2G-L22038 supports DC input voltages up to 5.5 V on pins A and B, regardless of the VCC supply voltage - enabling safe interfacing of 5 V signals into 3.3 V or 2.5 V systems without external protection components. This overvoltage tolerance is specified across the full operating temperature range and is verified per the Absolute Maximum Ratings table in the official datasheet.
Does the MC74VHC1G03DFT2G-L22038 support partial power-down functionality?
Yes, the MC74VHC1G03DFT2G-L22038 features IOFF circuitry that actively disables current flow through inputs and output when VCC = 0 V. This prevents back-driving and potential damage during hot-insertion or partial system power-down scenarios - a key requirement in modular industrial I/O systems and automotive domain controllers where subsystems power up/down independently.
What is the output drive capability of the MC74VHC1G03DFT2G-L22038 at 3.0 V supply?
At VCC = 3.0 V, the MC74VHC1G03DFT2G-L22038 can sink up to 8 mA while maintaining VOL ≤ 0.44 V (max) across −40 °C to +85 °C. This allows direct driving of LEDs, small-signal MOSFET gates, or optocoupler inputs without external buffers - verified in the DC Electrical Characteristics table under IOL test conditions.
Which package type does the MC74VHC1G03DFT2G-L22038 use, and what are its dimensions?
The MC74VHC1G03DFT2G-L22038 uses the SC-88A (also known as SOT-353) package: a 5-pin surface-mount outline measuring 2.0 mm × 1.25 mm × 0.95 mm with 0.65 mm lead pitch. This compact footprint is confirmed in the Ordering Information section and Mechanical Case Outline diagrams of the onsemi datasheet (Document Number MC74VHC1G03/D, Rev. 19).
