Product details
Overview
74AUP1Z04GW,125 from Nexperia is a low-power crystal oscillator driver IC with integrated enable input, internal pull-up resistor (RPU), and bias resistor (Rbias). It operates across 0.8 V to 3.6 V supply, delivers Schmitt-triggered EN input for noise immunity, supports -40 °C to +125 °C operation, and drives fundamental-mode quartz crystals in Pierce oscillator configurations for timing-critical embedded microcontrollers and real-time clocks.
For engineers reviewing the 74AUP1Z04GW,125 datasheet, 74AUP1Z04GW,125 pinout, 74AUP1Z04GW,125 application, or 74AUP1Z04GW,125 equivalent, key selection criteria include its dual-output (X2/Y) drive capability, 75 μA typical ICC in disable mode, 1.07–3.11 MΩ Rbias tolerance over frequency, <10 % overshoot/undershoot, and IOFF circuitry enabling partial power-down at output Y during system sleep states.
Technical Context
The 74AUP1Z04GW,125 implements an inverting amplifier core with internal feedback biasing via Rbias to stabilize the crystal's operating point near mid-supply voltage, ensuring linear gain region operation. Its EN input (active LOW) controls full functional enable/disable, while Schmitt-trigger thresholds scale with VCC (e.g., VIH = 0.75×VCC min at 0.8 V, 2.0 V min at 3.0–3.6 V).
Two distinct outputs serve complementary roles: X2 provides direct buffered inversion of X1 for crystal feedback path, while Y delivers inverted logic-level output referenced to GND/VCC - both support load capacitances up to 30 pF and exhibit propagation delays as low as 0.7 ns (X1→X2, VCC = 2.3–2.7 V, CL = 5 pF) and 1.4 ns (X1→Y, same conditions).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with ultra-low-voltage MCUs (e.g., ARM Cortex-M0+ at 0.9 V) and battery-powered IoT sensors without level-shifting. |
| Enable Input Threshold | VIH ≥ 0.75×VCC (min), VIL ≤ 0.25×VCC (max) - Schmitt-triggered EN ensures robust noise rejection across full VCC range, eliminating need for external RC filtering. |
| Quiescent Supply Current | 75 μA max (EN = GND) - enables >10-year battery life in always-on RTC backup circuits using coin cells. |
| Bias Resistance (Rbias) | 1.07–3.11 MΩ - sets stable DC operating point for crystal oscillation; value varies with frequency (e.g., 1.62 MΩ at 1 MHz) per Fig. 3. |
| Propagation Delay (X1→X2) | 0.7–3.9 ns (CL = 5–30 pF, VCC = 1.1–3.6 V) - supports crystal frequencies up to ~100 MHz in high-speed clock generation applications. |
| IOFF Leakage Current | ±0.75 μA (VCC = 0 V) - allows safe hot-plug or partial power-down of downstream logic while preserving signal integrity on Y output. |
| Output Drive Strength | VOH ≥ VCC − 0.11 V (IO = −20 μA); VOL ≤ 0.50 V (IO = 4.0 mA, VCC = 3.0 V) - ensures reliable CMOS logic interfacing across all supply voltages. |
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 optional. Designed for automated placement and reflow soldering in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Active-LOW enable input | Drives HIGH to disable device; places X1 HIGH via internal RPU, X2 LOW, Y HIGH - achieves ultra-low standby current. |
| 2 - GND | Ground reference | 0 V return path for all internal currents; must be low-impedance connection to minimize ground bounce in oscillator loop. |
| 3 - X1 | Inverting amplifier input | Primary crystal node connection; accepts feedback from X2; input capacitance 1.5 pF minimizes loading on crystal. |
| 4 - X2 | Inverting amplifier output | Drives crystal's other terminal; configured as part of Pierce oscillator feedback path; output capacitance 1.7 pF. |
| 5 - VCC | Positive supply | Power rail for internal logic and analog amplifier; decoupling capacitor (≥100 nF) required within 2 mm of pin. |
| 6 - Y | Inverted logic output | Provides buffered, rail-to-rail square wave for system clock distribution; supports IOFF mode when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide-Voltage Operation | 0.8 V to 3.6 V supply range enables single-part support across multiple MCU families (e.g., 1.2 V, 1.8 V, 3.3 V domains) without redesign. |
| Integrated Bias Network | On-chip Rbias (1.07–3.11 MΩ) eliminates external bias resistor, reducing BOM count and layout sensitivity in crystal oscillator design. |
| Low-Noise Output Switching | Overshoot/undershoot <10 % of VCC ensures clean edges into crystal and downstream logic, minimizing EMI and jitter accumulation. |
| Partial Power-Down Capability | IOFF circuitry maintains <±0.75 μA leakage on Y output during VCC ramp-down or removal - critical for fail-safe clock gating in safety-critical systems. |
| High-Temperature Rating | Specified from -40 °C to +125 °C ambient enables use in automotive under-hood ECUs and industrial motor drives without derating. |

FAQ
What is the function of the internal Rbias resistor in the 74AUP1Z04GW,125?
The internal Rbias resistor (1.07–3.11 MΩ) establishes a stable DC bias point near mid-supply voltage for the inverting amplifier core, ensuring operation in the high-gain linear region required for reliable crystal oscillation. It replaces an external bias resistor, simplifying design and improving consistency across temperature and process variation.
Can the 74AUP1Z04GW,125 drive a 32.768 kHz watch crystal directly?
Yes - the 74AUP1Z04GW,125 is explicitly designed for fundamental-mode quartz crystals including 32.768 kHz tuning-fork types. Its low ICC (75 μA), integrated RPU/Rbias, and optimized input/output capacitance (1.5 pF/1.7 pF) meet typical RTC crystal drive requirements without external components.
How does the EN pin behave when left unconnected?
Leaving EN unconnected is not recommended: the Schmitt-trigger input has no internal pull-up/down, risking undefined state and unintended oscillation. Per datasheet Section 1, EN must be driven HIGH (to VCC) to disable the device and achieve low-power mode with X1 pulled HIGH via RPU.
Is the Y output synchronized with the X2 output in the 74AUP1Z04GW,125?
No - Y is an inverted logic copy of X1 (not X2), so its edge timing differs. X1→Y propagation delay (1.4–10.9 ns) is longer than X1→X2 (0.7–3.9 ns), resulting in intentional skew. This allows Y to serve as a buffered system clock while X2 remains dedicated to crystal feedback with minimal delay.
