Product details
Overview
74LVC1GX04GW,125 from Nexperia is a single unbuffered crystal oscillator driver IC designed for fundamental-mode Pierce oscillator circuits. It features dual outputs (X2 and Y), 1.65 V to 5.5 V supply operation, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and operates across –40 °C to +125 °C. It enables low-power, small-footprint clock generation in microcontroller timing systems and IoT sensor nodes.
For engineers reviewing the 74LVC1GX04GW,125 datasheet, 74LVC1GX04GW,125 pinout, 74LVC1GX04GW,125 application, or 74LVC1GX04GW,125 equivalent, key selection criteria include its dual-output crystal drive capability, overvoltage-tolerant 5.5 V inputs, IOFF-enabled system-level power sequencing, and TSSOP6 package compatibility with high-density PCB layouts.
Technical Context
The 74LVC1GX04GW implements an unbuffered CMOS inverter core optimized for crystal excitation, with internal feedback biasing (via external 1 MΩ resistor) to operate the inverter in its linear gain region. Its X1 input drives both X2 (inverted buffered output) and Y (inverted unbuffered output), supporting split-load configurations where X2 feeds the crystal and Y drives downstream logic.
IOFF circuitry actively disables the Y output when VCC = 0 V, blocking backflow current during partial power-down-critical for mixed-voltage systems with asynchronous power rail sequencing. Input overvoltage tolerance to 5.5 V allows direct interfacing with 5 V logic while powered from 3.3 V or lower supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.65 V to 5.5 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Output drive | ±24 mA at VCC = 3.0 V - sufficient to drive typical 12 pF load crystals and moderate fanout logic |
| Propagation delay | 0.3–5.6 ns (X1→Y) - ensures stable oscillation startup and low jitter in crystal loops |
| Input voltage range | –0.5 V to 5.5 V - overvoltage tolerant inputs prevent damage during hot-plug or rail mismatch |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial control environments |
| Power dissipation | 250 mW max (TSSOP6) - enables use in thermally constrained space-constrained designs |
| Input capacitance | 5.0 pF - minimizes crystal load perturbation and maintains frequency accuracy |
Pinout & Package
TSSOP6 (SOT363-2) plastic thin shrink small outline package, 6-lead, 1.25 mm body width, 0.65 mm lead pitch, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | Not connected | No internal connection; must remain unconnected per design rules |
| GND | Ground reference | 0 V return path for all internal circuitry and output loads |
| X1 | Inverter input | Primary crystal feedback node; accepts inverted signal from X2 via external crystal network |
| X2 | Inverted buffered output | Drives crystal terminal; provides gain and phase inversion for Pierce loop closure |
| VCC | Supply voltage | Single positive rail powering entire device; IOFF active when VCC = 0 V |
| Y | Inverted unbuffered output | Low-capacitance clock output for downstream logic; disabled during power-down via IOFF |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output crystal drive | X2 delivers buffered crystal excitation; Y provides clean, low-skew clock output for MCU/system clocks |
| IOFF partial power-down | Y output high-impedance state when VCC = 0 V prevents backfeed into powered rails during sequencing |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - eliminates need for external clamping in mixed-supply systems |
| Wide temperature range | Specified from –40 °C to +125 °C - suitable for engine control units and industrial gateways |
| Low dynamic power | CPD = 35 pF at 3.3 V - reduces switching power in battery-powered timing applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G04GV,125 | Single-output (Y only); no X2 buffer; identical supply range and IOFF | Lacks dedicated crystal-drive output - requires external inverter stage for Pierce configuration | Select when only clock distribution (not crystal excitation) is needed |
| SN74LVC1G14DBVR | Schmitt-trigger input; higher hysteresis (≈0.3×VCC); same 6-pin SOT-23 package | Better noise immunity in electrically noisy environments but higher propagation delay (6.5 ns min) | Select for unreliable crystal signals or EMI-heavy under-hood locations |
Compared with 74LVC1GX04GW,125, the 74LVC1G04GV,125 lacks the X2 output required for self-contained Pierce oscillators, while the SN74LVC1G14DBVR trades lower jitter tolerance for superior noise rejection-making the 74LVC1GX04GW optimal for precision, low-power crystal drive where board space and component count are constrained.

FAQ
What is the function of the n.c. pin on the 74LVC1GX04GW,125?
Pin 1 is explicitly marked "n.c." (not connected) in the official Nexperia datasheet and package drawing. It has no internal bond wire or silicon connection. PCB layout must leave this pad unconnected and unstubbed to avoid parasitic coupling or unintended grounding that could affect crystal loop stability or EMI performance.
Can the 74LVC1GX04GW,125 drive a 32.768 kHz watch crystal directly?
Yes - the 74LVC1GX04GW,125 is validated for fundamental-mode 32.768 kHz tuning-fork crystals. Its low input capacitance (5.0 pF), high gain, and IOFF-enabled power sequencing make it suitable for RTC applications. External load capacitors (C1/C2) must be selected per crystal manufacturer's specified CL, typically 12.5 pF, using the formula CL = (C1 × C2)/(C1 + C2) + Cs, where Cs ≈ 5 pF.
How does the IOFF feature protect the device during partial power-down?
When VCC drops to 0 V, the IOFF circuitry forces the Y output into high-impedance state, blocking reverse current flow from powered downstream logic (e.g., 3.3 V MCU) into the unpowered 74LVC1GX04GW,125. This prevents latch-up, overheating, and bus contention-enabling safe power-rail sequencing in multi-voltage SoC systems without external isolation switches.
Why does the 74LVC1GX04GW,125 have two outputs (X2 and Y)?
X2 is a buffered, low-impedance output optimized to drive the crystal's capacitive load and sustain oscillation; Y is an unbuffered, low-capacitance output intended for clean clock distribution to digital logic. This separation isolates crystal loading from system clock fanout, improving frequency stability and reducing jitter compared to single-output drivers.
