Product details
Overview
74AUP1Z125GW,125 from Nexperia is a low-power crystal oscillator driver IC with integrated enable input, internal bias and pull-up resistors, and 3-state output. It operates across 0.8 V to 3.6 V supply, supports -40 °C to +125 °C ambient, features Schmitt-trigger inputs for noise immunity, and delivers propagation delays as low as 0.3 ns (VCC = 3.6 V, CL = 5 pF) on X1→Y path. It enables robust, space-constrained crystal clock generation in battery-powered IoT sensors.
For engineers reviewing the 74AUP1Z125GW,125 datasheet, 74AUP1Z125GW,125 pinout, 74AUP1Z125GW,125 application, or 74AUP1Z125GW,125 equivalent, key selection criteria include its wide VCC range (0.8–3.6 V), guaranteed 3-state disable behavior with EN-driven power-down mode, internal RPU/Rbias eliminating external components, and TSSOP6 package compatibility with high-density PCB layouts.
Technical Context
The 74AUP1Z125GW,125 implements a CMOS-based Pierce oscillator driver with dual outputs: buffered Y (3-state) and unbuffered X2. Its internal bias resistor (Rbias ≈ 1.62 MΩ typical) sets the inverter's DC operating point near mid-supply, ensuring linear gain region operation for stable oscillation startup and amplitude control. The EN input directly controls output state via Schmitt-trigger logic, enabling deterministic disable/enable transitions independent of VCC slew rate.
Unlike standard inverters, it integrates both pull-up (RPU) and bias (Rbias) resistors on-die-eliminating two external passives-and guarantees high-impedance OFF-state at Y when EN = HIGH. Its IOFF circuitry maintains partial power-down functionality even with VCC = 0 V, limiting leakage current to ±0.2 μA on Y and EN terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 0.8 V to 3.6 V - supports single-cell Li-ion, coin-cell, and multi-rail embedded systems without level-shifting. |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments. |
| Propagation Delay (X1→Y) | 1.4 ns (typ, VCC = 3.6 V, CL = 5 pF) - enables reliable timing in sub-500 MHz crystal oscillator loops. |
| Enable/Disable Time | 1.7 ns (typ, VCC = 3.6 V) - allows rapid clock gating for dynamic power management in MCU sleep/wake cycles. |
| Input Capacitance (X1) | 1.5 pF - minimizes crystal load perturbation and preserves frequency stability across temperature. |
| Power Dissipation Cap. | 24.3 pF (VCC = 3.6 V) - used to calculate dynamic power: PD = CPD × VCC² × fi × N. |
| IOFF Leakage Current | ±0.2 μA (VCC = 0 V) - ensures negligible standby current during full system power-down. |
Pinout & Package
TSSOP6 package (SOT363-2): plastic thin shrink small outline, 6-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input (active LOW) | Drives device into low-power disable mode; Schmitt-trigger threshold scales with VCC (e.g., 0.75×VCC min HI). |
| 2 (GND) | Ground reference | Primary return path for all internal currents; must be low-impedance connection to minimize noise coupling. |
| 3 (X1) | Clock input / crystal node | Connects to one terminal of quartz crystal; internal 1.5 pF capacitance affects load calculation. |
| 4 (X2) | Unbuffered inverter output | Direct feedback path to crystal; no 3-state control-always active when enabled. |
| 5 (VCC) | Supply voltage | Accepts 0.8–3.6 V; decoupling capacitor (≥100 nF) required within 2 mm of pin. |
| 6 (Y) | Buffered 3-state output | Delivers clean clock signal to downstream logic; high-impedance when EN = HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RPU and Rbias | Eliminates two external resistors (typically 1–10 MΩ), reducing BOM count and board area by ≥2.5 mm². |
| Schmitt-trigger EN input | Ensures clean enable/disable transitions even with slow-rising control signals (e.g., from GPIOs or RC networks). |
| IOFF partial power-down | Prevents back-driving and leakage when VCC is off but I/O pins remain biased-critical for hot-swap and battery backup designs. |
| Overvoltage-tolerant inputs | Withstands up to 3.6 V on EN/X1 regardless of VCC level-enables safe interfacing with 3.3 V logic in 1.8 V systems. |
| ESD protection | HBM >5000 V and CDM >1000 V-meets IEC 61000-4-2 Level 4 for robust handling in manufacturing and field deployment. |

|---|---|---|---|
| 74AUP1Z125GM,125 | XSON6 (SOT886) package: 1.0 × 1.45 × 0.5 mm, no leads, thermal pad not present. | Higher thermal resistance (3.3 mW/K derating above 74 °C) vs. TSSOP6 (3.7 mW/K above 83 °C); requires reflow profile adjustment. | Select for ultra-thin modules where height < 0.55 mm is mandatory; verify solder paste volume for void-free attachment. |

FAQ
What is the function of the internal Rbias resistor?
The internal Rbias resistor (1.08–3.08 MΩ, typical 1.62 MΩ) provides negative DC feedback to bias the inverter stage near mid-supply voltage, placing it in its high-gain linear region. This ensures reliable oscillation startup and stable amplitude control across voltage and temperature-eliminating the need for an external bias resistor and simplifying crystal oscillator design.
Can the 74AUP1Z125GW,125 drive crystals other than 32.768 kHz?
Yes-it supports fundamental-mode crystals from ~100 kHz to >20 MHz. Performance depends on crystal ESR and load capacitance matching: the internal 1.5 pF input capacitance (X1) and recommended external C1/C2 values must satisfy CL = (C1 × C2)/(C1 + C2) + Cs, where Cs = 1.5 pF. Higher frequencies require lower ESR crystals and tighter layout control.
How does the EN pin behave when pulled HIGH?
When EN is driven HIGH, the Y output enters high-impedance (Z) state, X2 is forced LOW, and X1 is pulled HIGH via the internal RPU resistor. This disables oscillation, reduces ICC to ≤75 μA, and places the device in a low-power disable mode-ideal for MCU sleep states while maintaining defined pin states for system-level predictability.
Is external decoupling required on VCC?
Yes-Nexperia specifies a minimum 100 nF ceramic capacitor placed within 2 mm of the VCC pin (Pin 5) and GND (Pin 2). This suppresses high-frequency switching noise generated by internal transconductance (gfs up to 39.2 mA/V), prevents supply rail collapse during fast enable transitions, and ensures stable oscillation across temperature and voltage corners.
