Product details
Overview
74HC1GU04GW,125 from Nexperia is a single unbuffered CMOS inverter in TSSOP5 (SOT353-1) package, operating from 2.0 V to 6.0 V supply, delivering symmetrical output impedance, balanced propagation delays (6–15 ns at VCC = 6.0 V, CL = 50 pF), and high noise immunity - used for signal inversion, crystal oscillator biasing, and linear amplifier stages in compact timing and interface circuits.
For engineers reviewing the 74HC1GU04GW,125 datasheet, 74HC1GU04GW,125 pinout, 74HC1GU04GW,125 application, or 74HC1GU04GW,125 equivalent, this device serves as a low-power, temperature-stable logic inverter with input clamp diodes enabling overvoltage-tolerant interfacing, ESD robustness (HBM >2000 V), and operation across -40 °C to +125 °C industrial and automotive-adjacent environments.
Technical Context
The 74HC1GU04GW,125 implements a single-stage unbuffered inverter topology with no internal gain staging, resulting in lower drive strength but improved propagation delay matching and reduced capacitive loading versus buffered variants. Its input includes integrated clamp diodes referenced to VCC and GND, permitting safe interface with signals exceeding supply rails when current-limited.
It operates within JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) voltage standards, supports rail-to-rail input/output swing, and exhibits consistent VIH/VIL thresholds across temperature (e.g., VIH = 4.8 V min at VCC = 6.0 V, -40 °C to +125 °C), making it suitable for mixed-voltage signal conditioning and oscillator feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Propagation Delay (tpd) | 6 ns (typ.) at VCC = 6.0 V, CL = 50 pF - ensures precise timing alignment in clock distribution and oscillator loops. |
| Output Drive Strength | ±2.6 mA at VCC = 6.0 V - sufficient for driving small capacitive loads (e.g., crystal networks, gate inputs) without external buffers. |
| Input Clamp Diodes | Integrated anode-to-GND / cathode-to-VCC - allows safe interfacing with voltages up to VCC + 0.5 V using series resistors. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, industrial control, and extended-range embedded applications. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - reduces need for external protection in space-constrained PCB layouts. |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 74 °C (TSSOP5) - derates linearly at 3.3 mW/K above 74 °C, supporting thermal-aware design. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, body width 1.25 mm, pin pitch 0.65 mm, exposed pad not present, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected (n.c.) | Internally unconnected - must be left floating or tied to GND per layout best practice; no electrical function. |
| 2 | Data input (A) | Inverting logic input with clamp diodes - accepts DC or AC-coupled signals up to VCC + 0.5 V when series-resistor limited. |
| 3 | Ground (GND) | Reference 0 V node - requires low-inductance connection to system ground plane for stable switching and noise immunity. |
| 4 | Data output (Y) | Inverted logic output with symmetrical rise/fall characteristics - drives capacitive loads up to 50 pF within specified tpd. |
| 5 | Supply voltage (VCC) | Positive supply rail - bypass capacitor (e.g., 100 nF ceramic) required within 5 mm for transient current stability. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered inverter architecture | Minimizes internal capacitance and propagation skew - critical for Pierce oscillator loop phase margin and jitter performance. |
| Wide VCC range (2.0–6.0 V) | Eliminates need for separate voltage regulators in multi-rail systems - supports direct use with Li-ion, USB, and legacy 5 V supplies. |
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew) - improves signal integrity in clock fanout and differential pair termination. |
| Latch-up immunity >100 mA | Guarantees robustness against transient current injection - essential in noisy industrial I/O and hot-swap environments. |
| CMOS low power dissipation | ICC < 20 μA at VCC = 6.0 V, static - enables battery-backed real-time clock buffering and always-on sensor interface stages. |
Applications
| Crystal Oscillator Biasing | Signal Level Translation |
|---|---|

| Linear Amplifier Stage | Reset Signal Inversion |
|
Use Scenario: Configured with feedback resistors to operate in analog linear mode for low-frequency signal amplification (e.g., sensor biasing). IC Role / Device Role / Timing Role: Functions as a high-input-impedance, rail-to-rail CMOS amplifier with open-loop gain ~20 and unity-gain bandwidth ~5 MHz. Use Value: Delivers cost-effective analog gain without dedicated op-amps - ideal for trimming reference voltages or conditioning thermistor outputs. |
Use Scenario: Inverts active-low reset signals (e.g., from pushbutton or supervisor IC) to meet active-high reset requirements of SoCs. IC Role / Device Role / Timing Role: Provides clean, fast logic inversion with sub-15 ns delay and low-glitch risk due to unbuffered edge fidelity. Use Value: Ensures deterministic reset assertion timing across temperature and supply variations - critical for fail-safe boot sequencing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1GU04GW,125 | Lower VCC range (1.65–5.5 V); higher speed (tpd = 3.2 ns typ. at VCC = 3.3 V); TTL-compatible inputs. | Better suited for 1.8 V/3.3 V-only systems; not rated for 5 V operation or -40 °C to +125 °C full range. | Select when prioritizing speed and low-voltage compatibility over 6 V tolerance and extended temperature coverage. |
| SN74AUP1G04DBVR | Ultra-low power (ICC < 0.9 μA typ.); VCC = 0.8–3.6 V; slower tpd (6.5 ns at VCC = 3.3 V, CL = 30 pF). | Optimized for battery-powered IoT nodes; lacks clamp diodes and 125 °C rating - unsuitable for harsh environments. | Choose for energy-constrained applications where supply voltage never exceeds 3.6 V and ESD robustness is secondary. |
Compared with 74HC1GU04GW,125, the LVC variant trades 6 V tolerance and extended temperature for speed and 1.65 V operation, while the AUP variant sacrifices voltage range, clamping, and temperature rating to achieve nanoamp-level quiescent current - selection depends on whether voltage flexibility, environmental ruggedness, or ultra-low power dominates the design priority.

FAQ
Can the 74HC1GU04GW,125 be used in a crystal oscillator circuit?
Yes - the 74HC1GU04GW,125 is explicitly qualified for Pierce oscillator configurations per its datasheet (Fig. 13). Its unbuffered inverter structure provides optimal phase gain and low noise for quartz crystals from 3 kHz to 600 kHz. External components include R1 (1–10 MΩ), R2 (adjustable per frequency), and load capacitors C1/C2 (e.g., 47 pF / 22 pF), with typical ICC ≈ 2 mA at VCC = 3 V and 1 MHz oscillation.
What is the purpose of Pin 1 (n.c.) on the TSSOP5 package?
Pin 1 is internally not connected - it serves only as a mechanical pin index for orientation and has no electrical function. The datasheet specifies it must remain unconnected (floating) or optionally tied to GND for mechanical stability; routing traces or vias to it provides no functional benefit and may risk solder bridging in fine-pitch assembly.
Does the 74HC1GU04GW,125 support 5 V operation with guaranteed timing at -40 °C to +125 °C?
Yes - the device is fully specified for VCC = 5.0 V across -40 °C to +125 °C per Table 6 (Recommended Operating Conditions) and Table 8 (Dynamic Characteristics). At VCC = 5.0 V and CL = 15 pF, tpd is 5 ns (typ.), and VOH/VOL remain within spec (VOH ≥ 4.13 V, VOL ≤ 0.33 V) across the full temperature range, confirmed in Tables 7 and 8.
How does the input clamp diode functionality affect interface design?
The integrated clamp diodes (anode to GND, cathode to VCC) allow safe interfacing with input signals exceeding VCC - e.g., a 5.5 V signal can be applied to Pin 2 if limited to ≤20 mA using a series resistor (e.g., 270 Ω for 500 mV drop). This eliminates external protection diodes in mixed-voltage systems, provided VI stays within absolute max ratings (VCC + 0.5 V) and current limits are observed.
