Product details
Overview
MC74VHC1G02P5T5G from onsemi is a single 2-input NOR gate logic IC in SOT-953 package, operating from 2.0 V to 5.5 V supply, with 3.5 ns typical propagation delay at 5 V, CMOS-level input thresholds, and over-voltage tolerant inputs/outputs up to 5.5 V-used for level-shifting between 3 V and 5 V digital subsystems in portable instrumentation.
For engineers reviewing the MC74VHC1G02P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range, propagation delay, input threshold compatibility (CMOS vs. TTL), IOFF partial power-down support, and SOT-953 footprint constraints in space-constrained PCB layouts.
Technical Context
This device implements a single 2-input NOR function using advanced high-speed CMOS technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling robust 3 V/5 V interface translation without external clamping.
The output stage supports ±8 mA drive at 3.0 V and features IOFF circuitry that disables I/O leakage when VCC = 0 V-critical for hot-swap and battery-backup systems where power domains are sequenced independently.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports mixed-voltage system integration without level shifters |
| tPD (typ) | 3.5 ns at 5 V, CL = 15 pF - enables use in sub-100 MHz digital control paths |
| Input Thresholds | CMOS-level (VIH = 3.15 V, VIL = 1.35 V @ VCC = 4.5 V) - ensures noise margin compatibility with 3.3 V logic families |
| IOFF Support | Active when VCC = 0 V - prevents back-powering and signal contention during partial power-down |
| Over-Voltage Tolerance | Inputs/outputs withstand up to 5.5 V regardless of VCC - eliminates need for external protection diodes in 5 V-tolerant 3 V designs |
| Drive Strength | ±8 mA at 3.0 V - sufficient to drive standard CMOS loads and small capacitive buses |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
SOT-953 (Case 527AE), 5-pin ultra-small surface-mount package measuring 1.00 mm × 0.80 mm × 0.37 mm with 0.35 mm pitch - optimized for high-density portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (Input) | First NOR input; accepts 0–5.5 V signals regardless of VCC |
| 2 | GND | Ground reference; must be connected before VCC for ESD-safe power sequencing |
| 3 | B (Input) | Second NOR input; identical electrical behavior to Pin 1 |
| 4 | Y (Output) | Active-low NOR output; drives high/low states with ±8 mA capability at 3 V |
| 5 | VCC | Positive supply; powers internal logic and enables IOFF when de-asserted |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2.0–5.5 V) | Enables direct integration into both 3.3 V microcontroller I/O banks and legacy 5 V peripheral interfaces |
| 5.5 V over-voltage tolerant I/O | Allows safe connection to 5 V buses while powered from 3 V, eliminating external voltage translators |
| IOFF partial power-down | Prevents current leakage through inputs/outputs when VCC is off-essential for battery-powered sleep modes |
| Low propagation delay (3.5 ns typ) | Supports timing-critical combinational logic in real-time control loops and fast state machines |
| AEC-Q100 qualified (-Q variant available) | Validated for automotive applications including body control modules and infotainment power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G02DBVR | TTL-compatible input thresholds (VIH = 2.0 V min @ 3.3 V); slightly higher ICC (10 µA max vs. 1.0 µA for MC74VHC1G02P5T5G) | Better suited for interfacing with older 3.3 V LVTTL peripherals; less ideal for ultra-low-quiescent-current battery systems | Select when interfacing legacy 3.3 V logic with marginal noise margins; verify VIH/VIL alignment with driving source |
| 74AUP1G02GW,125 | Lower VCC range (0.8–3.6 V); 3.8 ns tPD at 3.3 V; IOFF supported but no 5.5 V over-voltage tolerance | Optimized for sub-1 V core logic and ultra-low-power wearables; incompatible with 5 V signal domains | Choose only for single-supply ≤3.3 V designs requiring lowest possible dynamic power; not suitable for 5 V-tolerant use cases |
Compared with SN74LVC1G02DBVR and 74AUP1G02GW,125, the MC74VHC1G02P5T5G uniquely combines 5.5 V over-voltage tolerance, CMOS input thresholds, and −55 °C to +125 °C operation-making it the only option among the three qualified for mixed-voltage automotive and industrial interface applications without external protection.

FAQ
What is the maximum input voltage the MC74VHC1G02P5T5G can tolerate?
The MC74VHC1G02P5T5G supports input voltages up to 5.5 V regardless of VCC level-verified per Absolute Maximum Ratings table. This allows safe connection to 5 V signal sources even when powered from 2.0 V or 3.3 V, eliminating external clamping diodes in many interface designs. The specification applies to both pins A and B under all operating conditions.
Does the MC74VHC1G02P5T5G support partial power-down functionality?
Yes, the MC74VHC1G02P5T5G includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This prevents back-current flow and signal contention in systems with asynchronous power domain sequencing-such as battery-backed memory controllers or hot-pluggable modules where the MC74VHC1G02P5T5G remains connected during main supply removal.
What is the propagation delay of the MC74VHC1G02P5T5G at 3.3 V supply?
At VCC = 3.3 V and CL = 15 pF, the MC74VHC1G02P5T5G exhibits a typical propagation delay (tPLH/tPHL) of 4.5 ns, with a maximum of 6.5 ns over temperature (−55 °C to +125 °C). This value is specified in the AC Electrical Characteristics table and confirmed across all operating conditions for the SOT-953 packaged variant.
Is the MC74VHC1G02P5T5G pin-compatible with the MC74VHC1GT02 series?
No-the MC74VHC1G02P5T5G uses CMOS-level input thresholds, while the MC74VHC1GT02 variants use TTL-level thresholds (lower VIH/VIL). Although both share identical SOT-953 pinout and logic function, their input voltage compatibility differs significantly; substituting one for the other may cause logic misinterpretation in marginal signal conditions.
What package type does the MC74VHC1G02P5T5G use, and what are its dimensions?
The MC74VHC1G02P5T5G is packaged in SOT-953 (Case 527AE), a 5-pin ultra-compact surface-mount package measuring 1.00 mm × 0.80 mm × 0.37 mm with 0.35 mm lead pitch. Its small footprint supports high-density routing in portable electronics, and the package is Pb-free, halogen-free, and RoHS compliant per onsemi documentation.
