Overview
SN74AHC1GU04 from Texas Instruments is a single unbuffered CMOS inverter gate performing Y = A logic, operating from 2 V to 5.5 V supply, delivering ±8 mA output drive at 5 V, with 125 °C max operating temperature and SOT-23 (DBV) 5-pin package - used in crystal oscillator circuits, level translation, and signal conditioning in telecom infrastructure and audio systems.
For engineers reviewing the SN74AHC1GU04 datasheet, SN74AHC1GU04 pinout, SN74AHC1GU04 application, or SN74AHC1GU04 equivalent, this page delivers verified electrical specs, thermal metrics, oscillator design guidance, and real-world implementation constraints - all confirmed for the DBV-packaged SN74AHC1GU04 variant.
Technical Context
This device implements a single-stage CMOS inverter with unbuffered output topology optimized for analog use in Pierce crystal oscillators. Its input voltage tolerance extends to 5.5 V regardless of VCC, enabling down-voltage translation across mixed-supply systems.
It features rail-to-rail output swing, low propagation delay (3.5 ns typical at 5 V, CL = 15 pF), and high noise immunity with VIH/VIL thresholds defined across 2–5.5 V supply range - supporting robust operation in noisy industrial and broadcast environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 5.5 V - supports direct interface with 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Output Drive | ±8 mA at 5 V - sufficient to drive crystal loads and moderate capacitive loads (≤50 pF) without external buffering. |
| Propagation Delay | 3.5 ns (typ) at 5 V, CL = 15 pF - enables timing-critical signal inversion in high-speed control paths. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| ESD Rating | 2000 V HBM - meets IEC 61000-4-2 system-level ESD immunity requirements when properly decoupled. |
| Input Tolerance | Inputs accept up to 5.5 V independent of VCC - allows safe interfacing with higher-voltage controllers or legacy 5 V peripherals. |
| Power Dissipation | 7.3 pF Cpd at 1 MHz - predicts ultra-low dynamic power in battery-powered sensor nodes and portable audio mixers. |
Pinout & Package
SOT-23 (DBV) 5-pin plastic package, 2.90 mm × 1.60 mm body size, 1.45 mm max height, JEDEC MO-178 compliant. Pin 1 marked via index area; tape-and-reel packaging (3000 pcs/reel, Q3 quadrant orientation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused terminal - must remain unconnected; no pull-up/down or routing required. |
| 2 (A) | Inverter input | CMOS-compatible digital input accepting 0–5.5 V; requires explicit bias (VCC or GND) if unused to prevent floating state. |
| 3 (GND) | Ground reference | Primary return path for logic and switching currents; must connect to low-impedance system ground plane. |
| 4 (Y) | Inverter output | Unbuffered CMOS output driving complementary logic; not intended for bus contention or wired-OR configurations. |
| 5 (VCC) | Supply voltage | Single positive supply input (2–5.5 V); requires local 0.1 µF ceramic bypass capacitor placed ≤2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Output | Enables linear-region operation for crystal oscillator feedback loops - critical for stable 1–50 MHz fundamental-mode resonator designs. |
| Wide Supply Range | 2 V to 5.5 V operation eliminates need for dedicated LDOs in multi-rail systems - simplifies power architecture in set-top boxes and cameras. |
| Overvoltage-Tolerant Inputs | Accepts 5.5 V inputs at any valid VCC - permits direct connection to 5 V microcontrollers while powered from 3.3 V rails. |
| Latch-Up Immunity | Exceeds 250 mA per JESD 17 - ensures robustness against transient current surges during hot-plug or ESD events in server backplanes. |
| Low Input Leakage | ±1 µA max II over full temperature range - preserves signal integrity in high-impedance sensor interfaces and precision timing networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1GU04DBVR | Lower VCC range (1.65–5.5 V); 24 mA drive at 3.3 V; higher input capacitance (4.5 pF vs 2 pF) | Better suited for 1.8 V systems; less optimal for crystal oscillator linearity due to buffered output | Select when operating below 2 V or requiring stronger drive in 3.3 V logic domains - avoid for oscillator use. |
| 74AUP1G04GW,125 | Ultra-low power (0.9 µA ICC); 1.1–3.6 V range; 4 mA drive at 3.3 V; smaller SC-70 package | Optimized for battery-powered IoT sensors; insufficient drive for most crystal loads above 10 MHz | Prefer for always-on wearable devices with strict quiescent current limits - not recommended for timing-critical oscillator designs. |
Compared with SN74AHC1GU04DBVR, the SN74LVC1GU04DBVR offers higher drive but sacrifices oscillator linearity, while the 74AUP1G04GW,125 minimizes power at the cost of frequency capability and load drive - making SN74AHC1GU04 the balanced choice for mixed-signal timing and translation.

FAQ
What is the maximum operating temperature for SN74AHC1GU04?
The SN74AHC1GU04 is rated for continuous operation from –40 °C to +125 °C ambient temperature. This extended range is validated per JEDEC JESD22-A108 and supports deployment in under-hood automotive modules, industrial motor controllers, and outdoor base station equipment where thermal margins are critical. The SN74AHC1GU04 maintains specified VOH/VOL and propagation delay performance across this full range.
Can SN74AHC1GU04 be used in crystal oscillator circuits?
Yes - the SN74AHC1GU04 is explicitly designed for crystal oscillator use due to its unbuffered output stage, which enables linear-region operation essential for sustaining oscillation in Pierce configurations. TI's datasheet confirms its suitability for 32.768 kHz watch crystals and fundamental-mode MHz-range quartz resonators. The SN74AHC1GU04's low input capacitance (2 pF) and symmetric drive minimize frequency pulling and improve stability.
Does SN74AHC1GU04 support voltage-level translation?
Yes - the SN74AHC1GU04 accepts input voltages up to 5.5 V regardless of VCC, enabling reliable down-translation (e.g., 5 V input to 3.3 V output). This is confirmed by VIH/VIL specifications across 2–5.5 V supply and input clamp current ratings. When used for level translation, the SN74AHC1GU04 maintains rail-to-rail output swing and sub-10 ns propagation delay - critical for maintaining timing integrity in mixed-voltage systems.
What is the recommended bypass capacitor for SN74AHC1GU04?
Texas Instruments specifies a 0.1 µF ceramic capacitor placed within 2 mm of the SN74AHC1GU04 VCC pin as mandatory for stable operation. This value is derived from the device's 7.3 pF power dissipation capacitance and fast edge rates (≤10 ns), which generate high-frequency supply transients. The SN74AHC1GU04 datasheet further recommends paralleling with a 1 µF capacitor if board space allows - especially in systems with shared power rails or high-current peripherals.
Is SN74AHC1GU04 pin-compatible with other 5-pin logic gates?
No - SN74AHC1GU04 has a unique pinout: Pin 1 is NC, Pin 2 is input (A), Pin 3 is GND, Pin 4 is output (Y), Pin 5 is VCC. This differs from standard 5-pin inverters like SN74LVC1G04 (Pin 1 = A, Pin 2 = GND, Pin 3 = Y, Pin 4 = VCC, Pin 5 = NC), making direct PCB replacement impossible without layout revision. Always verify pin mapping before substituting the SN74AHC1GU04 in existing designs.
