Product details
Overview
74AHC1G00QSE-7 from Diodes Incorporated is an automotive-grade single 2-input positive NAND gate in SOT353 package, operating from 2.0V to 5.5V supply, delivering ±8mA output drive at 4.5V, with AEC-Q100 Grade 1 qualification (−40°C to +125°C), and Schmitt-trigger inputs for robust noise immunity in harsh environments - used in engine control unit logic interfacing and body electronics signal conditioning.
For engineers reviewing the 74AHC1G00QSE-7 datasheet, 74AHC1G00QSE-7 pinout, 74AHC1G00QSE-7 application, or 74AHC1G00QSE-7 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed automotive temperature compliance, real-world drive capability data, and precise package thermal metrics - all critical for high-reliability logic design and AEC-Q100-compliant BOM validation.
Technical Context
This device implements a single Boolean NAND function (Y = A·B) with push-pull CMOS output stage and Schmitt-trigger input thresholds, enabling reliable operation with slow-rising or noisy signals across its full 2.0–5.5V VCC range. Input voltage tolerance extends beyond VCC, supporting mixed-voltage interface scenarios without level shifters.
Propagation delay is tightly balanced between rising and falling edges (tPHL/tPLH ≤ 1.5ns mismatch at VCC = 5V, CL = 15pF), and output drive strength remains symmetric (±8mA at 4.5V), ensuring predictable timing margins in synchronous logic chains and fanout-critical nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input positive NAND gate (Y = A·B); enables compact discrete logic implementation without multi-gate ICs. |
| Supply Voltage Range | 2.0V to 5.5V; supports direct interface with 3.3V microcontrollers and legacy 5V systems without regulators. |
| Output Drive | ±8mA at VCC = 4.5V; drives ≥10 LS-TTL loads or 20 AHC loads, sufficient for board-level signal distribution. |
| Propagation Delay | Max 7.0ns at VCC = 5V, CL = 15pF; ensures sub-10ns timing in high-speed control paths like PWM sync or sensor debouncing. |
| Operating Temperature | −40°C to +125°C (Grade 1); qualified per AEC-Q100, suitable for under-hood automotive modules. |
| Input Threshold | Schmitt-trigger action (typ. 30%–70% VCC hysteresis); rejects >100mV noise on slow edges, eliminating external RC filtering. |
| ESD Rating | 2kV HBM, 1kV CDM; exceeds AEC-Q100-002/-011, reducing field failure risk in automated assembly and service environments. |

| 2 (B) | Data Input | Secondary logic input with identical Schmitt characteristics; enables true two-input NAND functionality. |
| 3 (GND) | Ground Reference | Return path for all internal current; must be low-impedance to maintain noise margin and switching stability. |
| 4 (Y) | Data Output | Push-pull CMOS output capable of sourcing/sinking ±8mA; directly interfaces with downstream logic or LED indicators. |
| 5 (VCC) | Power Supply | Single-supply rail for entire gate; decoupling capacitor (≥100nF) required within 5mm for stable high-speed operation. |
Key Features
| Feature | Design Value |

FAQ
What is the maximum allowable input voltage for 74AHC1G00QSE-7 when VCC = 3.3V?
The absolute maximum input voltage is −0.5V to 6.5V, independent of VCC. At VCC = 3.3V, inputs may safely accept signals up to 6.5V - enabling direct connection to 5V sensors or open-drain buses without level-shifting circuitry, provided current-limiting resistors are used to constrain IIK to ≤±20mA.
Can 74AHC1G00QSE-7 drive an LED directly?
Yes - with appropriate current limiting. At VCC = 5V, the output can sink up to 8mA (IOL). To drive a standard 2V, 20mA LED, use a series resistor ≥375Ω (calculated as (5V − 2V)/8mA). For higher brightness, pair with a transistor buffer; direct drive is suitable only for indicator LEDs with low forward current requirements.
Is the SOT353 package thermally adequate for continuous 8mA output operation at +125°C ambient?
Yes - with proper PCB layout. The SOT353 has θJA = 385°C/W on standard FR-4. At 8mA sink, power dissipation is ~40mW (5V × 8mA), resulting in ΔT ≈ 15.4°C above ambient. With TA = +125°C, junction temperature reaches ~140.4°C - below the 150°C absolute max, provided minimum recommended copper pad area (≥25mm²) is used per Diodes' layout guidelines.
Does 74AHC1G00QSE-7 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied directly to VCC or GND per the datasheet's Recommended Operating Conditions (Note 7). Schmitt-trigger inputs prevent floating states, but leaving them unconnected risks increased ICC, noise coupling, and potential oscillation. Direct connection eliminates leakage paths and ensures deterministic logic state without added components.
