Product details
Overview
74AUP1Z125GM,132 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, features Schmitt-trigger inputs for noise immunity, and delivers stable X1→X2/X1→Y propagation delays as low as 0.3 ns (VCC = 3.6 V, CL = 5 pF). It enables ultra-compact, low-power clock generation in space-constrained portable and battery-powered systems.
For engineers reviewing the 74AUP1Z125GM,132 datasheet, 74AUP1Z125GM,132 pinout, 74AUP1Z125GM,132 application, or 74AUP1Z125GM,132 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 validated operation from –40 °C to +125 °C in XSON6 package.
Technical Context
The 74AUP1Z125GM implements a CMOS-based Pierce oscillator driver with dual outputs: buffered Y (3-state) and unbuffered X2. Its internal Rbias (~1.62 MΩ typical) sets the inverter's DC bias point near mid-supply, enabling linear-region amplification for reliable crystal startup and sustained oscillation. The Schmitt-trigger EN input ensures robust enable/disable control across full VCC range without external hysteresis.
Functionally, it supports active-low enable (EN = L → Y enabled; EN = H → Y = high-Z), with X1 as crystal input and X2 as direct inverter output. In disable mode, X1 is pulled HIGH via internal RPU (~15 µA pull-up current), X2 driven LOW, and Y placed in high-impedance OFF-state - minimizing system leakage and dynamic power during standby.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 0.8 V to 3.6 V - supports single-supply operation across ultra-low-voltage microcontrollers and mixed-voltage SoCs. |
| Operating Temperature | –40 °C to +125 °C - qualified for automotive under-hood and industrial edge computing environments. |
| X1→Y Propagation Delay | 1.4 ns (typ) at VCC = 3.6 V, CL = 5 pF - enables precise timing in high-frequency crystal reference paths. |
| IOFF Leakage Current | ±0.2 µA max at VCC = 0 V - ensures true partial power-down of output Y during system sleep states. |
| Input Capacitance (X1) | 1.5 pF - minimizes crystal load capacitance impact, simplifying CL matching for ±10 ppm stability. |

Pinout & Package
XSON6 plastic extremely thin small outline package; no leads; 6 terminals; body 1.0 × 1.45 × 0.5 mm (SOT886).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable input (active LOW) | Drives device into low-power disable mode when HIGH; Schmitt-trigger input tolerates slow edges across full VCC range. |
| 2 (GND) | Ground reference (0 V) | Common return path for all internal circuitry and output loads; decoupling capacitor must be placed adjacent. |
| 3 (X1) | Crystal input / inverter input | Primary node for connecting crystal series leg; internal RPU pulls HIGH in disable mode to prevent floating. |
| 4 (X2) | Unbuffered inverter output | Direct output of internal inverter stage; used for feedback path in Pierce oscillator configuration. |
| 5 (VCC) | Supply voltage input | Power rail for all logic and analog functions; requires local 0.47 µF + 100 µF decoupling per datasheet test setup. |
| 6 (Y) | Buffered 3-state output | Enabled only when EN = LOW; provides clean, isolated clock signal to downstream logic with high-Z disable state. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RPU and Rbias | Eliminates two external resistors (RPU ≈ 15 µA pull-up; Rbias ≈ 1.62 MΩ), reducing BOM count and PCB area in crystal oscillator designs. |
| True 3-state Output (Y) | EN = HIGH forces Y into high-impedance OFF-state with IOZ ≤ ±0.1 µA, enabling safe bus sharing and multi-source clock routing. |
| Wide-Voltage Schmitt Inputs | EN and X1 inputs meet Schmitt-trigger thresholds across 0.8–3.6 V, rejecting noise and enabling direct interface with GPIOs of diverse logic families. |
| Low ICC Supply Current | 75 µA max at full temperature range - enables >10-year battery life in always-on RTC or sensor wake-up circuits. |
| Overvoltage-Tolerant Inputs | Withstands up to 3.6 V on EN/X1 even when VCC = 0 V - prevents latch-up during hot-plug or power sequencing events. |

FAQ
What is the purpose of the internal RPU and Rbias resistors?
The internal RPU (pull-up) resistor connects X1 to VCC during disable mode (EN = HIGH), preventing floating input and ensuring predictable oscillator shutdown. The Rbias (bias) resistor provides negative feedback to set the inverter's DC operating point near mid-supply, enabling stable linear-region amplification essential for reliable crystal startup and sustained oscillation across voltage and temperature.
Can the 74AUP1Z125GM,132 drive crystals directly without external capacitors?
No - external load capacitors C1 and C2 are required to form the Pierce oscillator network with the crystal. The 74AUP1Z125GM,132 provides internal biasing but does not replace the crystal's specified load capacitance (CL). Designers must calculate C1/C2 values using CL and the device's 1.5 pF input capacitance (Cs) to meet crystal manufacturer specifications and achieve target frequency accuracy.
How does the EN pin behave during power-up or brown-out conditions?
The EN pin features Schmitt-trigger action with hysteresis defined across all VCC levels (e.g., VIH = 0.75×VCC, VIL = 0.25×VCC at VCC = 3.6 V), ensuring clean, bounce-free enable/disable transitions during supply ramp-up or droop. When VCC is below 0.8 V, the device remains in high-impedance state with negligible ICC, preventing unintended oscillation or output contention.
Is the X2 output intended for external connection or internal feedback only?
X2 is the unbuffered inverter output and is designed for internal feedback to the crystal - not for driving external loads. It exhibits higher output impedance and less drive strength than Y. Connecting external circuitry to X2 risks degrading oscillation margin, increasing jitter, or causing startup failure; only Y should be used as the system clock output.
