Product details
Overview
NC7SZU04L6X from onsemi is a single unbuffered inverter in the TinyLogic UHS family, designed specifically for crystal oscillator and analog applications where linear-region operation is required. It operates across 1.65 V to 5.5 V supply voltage, delivers ±32 mA output drive at 4.5 V, and achieves 3.9 ns propagation delay at 5 V with 15 pF load.
For engineers reviewing the NC7SZU04L6X datasheet, pinout, applications, or equivalent options, key selection criteria include unbuffered topology for oscillator feedback paths, micro-size SIP6 package compatibility, low quiescent current (<2 µA at 5.5 V), and verified performance across industrial temperature range (−40°C to +85°C).
Technical Context
The NC7SZU04L6X implements an unbuffered CMOS inverter stage-lacking internal gain staging-to enable controlled linear-mode biasing essential for Pierce oscillator configurations. Its symmetrical pull-up/pull-down strength (±32 mA at 4.5 V) ensures stable oscillation startup and amplitude control without external resistive loading.
This device uses advanced CMOS fabrication to maintain ultra-high speed (3.9 ns tPLH/tPHL at 5 V) while achieving sub-2 µA ICC quiescent current and supporting broad VCC operation from 1.65 V to 5.5 V-enabling direct drop-in use in both 1.8 V and 5 V systems without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without voltage translation |
| Propagation Delay | 3.9 ns max at 5 V, 15 pF - enables high-frequency oscillator designs up to ~100 MHz fundamental |
| Output Drive | ±32 mA at 4.5 V - provides sufficient current for driving crystal loads and sustaining oscillation under capacitive/parasitic conditions |
| Quiescent Current | <2 µA at 5.5 V, 25°C - minimizes standby power in battery-sensitive oscillator circuits |
| Input Thresholds | VIH = 0.80×VCC, VIL = 0.20×VCC at VCC ≥3.0 V - ensures robust noise margin across full supply range |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade timing stability in embedded and automotive subsystems |
| ESD Rating | 4000 V HBM - protects against handling damage during board assembly and oscillator tuning |
Pinout & Package
SIP6 (Case 127EB) is a 1.45 mm × 1.0 mm, 6-pin ultra-thin leadless package with exposed thermal pad; pin 1 is marked by dot or beveled corner, and pins are arranged in single-row configuration with no leads extending beyond body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No-connect terminal - must remain unconnected; not internally bonded |
| 2 | A | Inverter input - accepts TTL/CMOS-compatible logic levels or analog bias for oscillator feedback |
| 3 | GND | Ground reference - serves as return path for all internal currents and substrate reference |
| 4 | Y | Inverter output - drives crystal network or next-stage input; unbuffered output enables linear-region operation |
| 5 | NC | No-connect terminal - electrically isolated; no internal connection |
| 6 | VCC | Positive supply - powers internal CMOS transistors; bypass capacitor recommended near pin |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unbuffered inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Buffered inverter; higher propagation delay (4.5 ns min at 3.3 V); no guaranteed linear-region operation | Not suitable for crystal oscillator feedback; intended for digital logic inversion only | Select only if application requires strict digital inversion with no analog biasing |
| 74LVC1G14GW,125 | Schmitt-trigger input; hysteresis prevents noise-induced switching; not unbuffered | Used in noisy environments for signal conditioning; cannot replace NC7SZU04L6X in oscillator loops | Choose when input signal has slow edges or high noise; avoid for oscillator use |
Compared with SN74LVC1G04DBVR and 74LVC1G14GW,125, the NC7SZU04L6X uniquely supports intentional linear-mode operation for oscillator gain, offers lower propagation delay at 5 V, and guarantees unbuffered topology-making it irreplaceable in crystal-based timing circuits despite similar pin count and package size.

FAQ
What is the primary circuit role of the NC7SZU04L6X in oscillator designs?
The NC7SZU04L6X serves as the unbuffered gain element in Pierce and Colpitts crystal oscillator topologies. Its lack of internal buffering allows controlled operation in the linear region-essential for sustaining oscillation-while its balanced ±32 mA drive ensures stable amplitude across varying crystal ESR and load capacitance. This function is explicitly defined in the onsemi datasheet for NC7SZU04L6X.
Can the NC7SZU04L6X operate from a 1.8 V supply, and what performance is guaranteed?
Yes, the NC7SZU04L6X is fully specified from 1.65 V to 5.5 V. At 1.8 V, it delivers guaranteed propagation delay ≤11.7 ns (with 15 pF load), VIH ≥1.53 V, VIL ≤0.27 V, and ICC <2 µA. These parameters are validated across −40°C to +85°C per the official NC7SZU04L6X datasheet revision 8.
Why does the NC7SZU04L6X have two NC pins in the SIP6 package?
The NC7SZU04L6X SIP6 package contains two no-connect pins (pins 1 and 5) due to die pad layout constraints and internal bond wire routing limitations-not functional omission. These pins are electrically isolated and must remain unconnected per the NC7SZU04L6X datasheet pin definitions and absolute maximum ratings table.
Is the NC7SZU04L6X suitable for use as a general-purpose logic inverter in digital signal paths?
While the NC7SZU04L6X performs logical inversion (L→H, H→L), its unbuffered design causes slower edge rates and potential metastability when driven by slow-rising inputs. It is optimized for oscillator feedback-not digital logic. For standard inversion, onsemi recommends buffered variants like NC7SZ04L6X; this distinction is clearly stated in the NC7SZU04L6X datasheet features section.
What thermal considerations apply when using the NC7SZU04L6X in linear-mode oscillator operation?
When biased in the linear region for oscillator use, the NC7SZU04L6X can draw significant simultaneous conduction current, raising junction temperature. The SIP6 package has θJA = 154°C/W; designers must limit duty cycle and ambient temperature, and verify power dissipation using ICCPEAK data from the NC7SZU04L6X DC electrical characteristics table to avoid exceeding TJ = +150°C.
