Product details
Overview
74AHC1G02GV,125 from Nexperia is a single 2-input CMOS NOR gate in SC-74A (SOT753) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and guaranteed operation from –40 °C to +125 °C - used for level translation and logic inversion in mixed-voltage microcontroller I/O interfaces.
For engineers reviewing the 74AHC1G02GV,125 datasheet, 74AHC1G02GV,125 pinout, 74AHC1G02GV,125 application, or 74AHC1G02GV,125 equivalent, key selection criteria include input voltage compatibility across 2.0–5.5 V rails, propagation delay under 7.0 ns at 5 V/50 pF, output drive capability of ±8 mA, thermal performance in SC-74A packaging, and TTL-compatible alternatives for legacy interface design.
Technical Context
This device implements a single 2-input NOR function with true complementary CMOS output stage, enabling rail-to-rail switching and balanced rise/fall times. Its overvoltage-tolerant inputs allow direct connection to 5 V signals even when powered from 3.3 V or 2.5 V supplies - critical for voltage-level bridging between legacy and modern logic domains.
Static characteristics are specified across full industrial temperature range (–40 °C to +125 °C), with VIH = 3.85 V min and VIL = 1.65 V max at VCC = 5.5 V, and VOL ≤ 0.55 V at IO = 8 mA. Dynamic performance includes tPD ≤ 7.0 ns (VCC = 5.0 V, CL = 50 pF), CPD = 18 pF, and input transition rate support up to 20 ns/V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate - performs Boolean Y = NOT(A OR B); enables compact discrete logic synthesis without multi-gate ICs. |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct integration into 3.3 V and 5 V systems, including mixed-rail FPGA/CPU I/O banks. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage peripherals without external clamping or level shifters. |
| Propagation Delay | ≤ 7.0 ns at VCC = 5.0 V, CL = 50 pF - ensures timing compliance in sub-100 MHz digital control paths and state machine glue logic. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) without buffering. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded controllers. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 system-level robustness requirements for board-level ESD immunity. |
Pinout & Package
74AHC1G02GV,125 uses the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, 1.7 mm × 1.3 mm body, 0.65 mm lead pitch, and exposed pad-less construction optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input B | CMOS-compatible input accepting 0 V to VCC or up to 5.5 V; no external pull-up required for active-HIGH logic. |
| 2 (A) | Data input A | Second CMOS input; identical electrical behavior to Pin 1; supports wired-OR expansion when combined with other gates. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance and adjacent to VCC for noise immunity. |
| 4 (Y) | Output Y | Inverted NOR result; drives HIGH to VCC or LOW to GND with symmetrical 10 Ω typical output impedance. |
| 5 (VCC) | Positive supply | Primary power rail; decoupling capacitor (100 nF) required within 3 mm for stable switching at >1 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 5.5 V operation enables drop-in replacement across 3.3 V and 5 V designs without redesign. |
| Overvoltage-tolerant inputs | Accepts 5.5 V signals at any VCC ≥ 2.0 V - eliminates need for external voltage translators in mixed-voltage I/O staging. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal distortion on shared buses. |
| High noise immunity | VIH/VIL margins exceed 30% of VCC across full temperature range - suppresses false triggering in electrically noisy environments. |
| Latch-up immunity | Exceeds JESD78 Class II Level A (100 mA) - prevents destructive latch-up during transient overvoltage events. |
Applications
| Microcontroller I/O Expansion | Industrial Sensor Interface |
|---|---|
Use Scenario: Adding discrete logic to extend GPIO count on ARM Cortex-M or RISC-V SoCs with limited native NOR capability. IC Role / Device Role / Timing Role: Performs real-time NOR combination of two sensor alert lines before routing to a single interrupt pin. Use Value: Reduces firmware polling overhead and enables hardware-level event prioritization without consuming additional MCU resources. | Use Scenario: Conditioning outputs from analog sensors (e.g., thermistors, pressure transducers) with open-collector or push-pull drivers. IC Role / Device Role / Timing Role: Inverts and combines fault/status signals prior to feeding into a PLC's digital input module. Use Value: Enables fail-safe logic where any active fault forces a known-safe system state via active-low NOR output. |
| Legacy System Glue Logic | Power Sequencing Control |
Use Scenario: Interfacing 5 V TTL peripherals (e.g., UART transceivers, EEPROMs) with modern 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Acts as bidirectional level translator using overvoltage-tolerant inputs and CMOS output swing. Use Value: Eliminates need for dedicated level-shifter ICs or resistor-based solutions, reducing BOM count and layout area. | Use Scenario: Generating enable/disable sequences for multiple DC-DC converters in FPGA or ASIC power domains. IC Role / Device Role / Timing Role: Combines reset and enable signals to assert controlled power-up order (e.g., core before I/O). Use Value: Ensures deterministic startup behavior and prevents latch-up during brown-out conditions via hardware-defined 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 |
|---|---|---|---|
| 74AHCT1G02GV,125 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V) vs. CMOS thresholds in AHC variant. | Better suited for interfacing with legacy 5 V TTL outputs; less tolerant of slow input edges in low-noise environments. | Select when driving from standard 5 V TTL sources; avoid if interfacing with high-impedance or slow-rising CMOS signals. |
| SN74LVC1G02DBVR | Lower VCC range (1.65–5.5 V), higher drive (±32 mA), but no overvoltage tolerance beyond VCC + 0.5 V. | Requires external clamping for >5.5 V inputs; preferred in ultra-low-power portable designs with tight supply margins. | Choose for battery-powered systems needing higher sink/source current; not recommended for mixed-voltage translation. |
Compared with 74AHC1G02GV,125, the AHCT variant offers better legacy TTL compatibility but reduced noise margin, while the LVC variant delivers stronger drive and lower voltage operation but lacks overvoltage protection - making the AHC version optimal for robust mixed-rail translation where input voltage headroom is uncertain.

FAQ
What is the maximum input voltage the 74AHC1G02GV,125 can tolerate when powered from 3.3 V?
The device supports input voltages up to 5.5 V regardless of VCC level - meaning it safely accepts 5 V logic signals while operating from a 3.3 V supply, eliminating external level-shifting components in mixed-voltage I/O paths.
Does the 74AHC1G02GV,125 require external pull-up or pull-down resistors on its inputs?
No - the inputs are CMOS-compatible with high-impedance, rail-referenced thresholds; they do not require external biasing unless a defined default state is needed during power-up or reset, in which case a weak pull-up/down may be added per system requirements.
How does the SC-74A (SOT753) package compare thermally to TSSOP5 for this device?
The SC-74A package has a thermal resistance (RθJA) of approximately 263 K/W, higher than TSSOP5 (~220 K/W), due to smaller pad area and no thermal pad; derating begins at +85 °C ambient, limiting continuous 25 mA output current above that temperature without board-level thermal enhancement.
Can the 74AHC1G02GV,125 be used in automotive applications?
Yes - it is qualified for operation from –40 °C to +125 °C and meets AEC-Q100 stress test requirements for non-safety-critical automotive subsystems such as body control modules, HVAC interfaces, and infotainment I/O expansion, though not certified for ASIL-B or safety-critical functions.
