Nexperia USA Inc. 74AUP1Z04GM,115

Overview

74AUP1Z04GM,115 from Nexperia is a low-power crystal oscillator driver IC with integrated enable input, internal pull-up resistor (RPU), and bias resistor (Rbias). It functions as an inverting amplifier in Pierce oscillator configurations for quartz crystals, operating across 0.8 V to 3.6 V supply, supporting -40 °C to +125 °C ambient, and delivering propagation delays as low as 0.7 ns (X1→X2, VCC = 2.3–2.7 V, CL = 5 pF). It enables power-gated crystal operation in battery-powered IoT sensors and real-time clock subsystems.

For engineers reviewing the 74AUP1Z04GM,115 datasheet, 74AUP1Z04GM,115 pinout, 74AUP1Z04GM,115 application, or 74AUP1Z04GM,115 equivalent, key selection criteria include its Schmitt-trigger EN input for noise-immune disable control, IOFF circuitry enabling partial power-down at output Y, ultra-low ICC (≤75 μA), and guaranteed operation down to 0.8 V - critical for energy-constrained microcontroller clock trees and wearable timing modules.

Technical Context

The 74AUP1Z04GM implements a single-stage CMOS inverter core with internal Rbias (~1.07–3.11 MΩ) to bias the X1 input near mid-supply, ensuring linear-region amplification for stable crystal oscillation. Its dual-output architecture separates X2 (inverted crystal feedback path) and Y (buffered logic output), allowing independent use of oscillator signal and system-enable control.

Schmitt-trigger action on the EN pin (VIH/VIL thresholds scaling with VCC) ensures robust enable/disable transitions across the full 0.8–3.6 V range, while IOFF circuitry isolates Y when VCC = 0 V, preventing backfeed during power sequencing. The device complies with JEDEC standards JESD8-12 through JESD8C and exceeds JESD78B Class II latch-up immunity (>100 mA).

FAQ

What is the function of the internal Rbias resistor?

The internal Rbias resistor (1.07–3.11 MΩ) provides negative DC feedback from X2 to X1, biasing the inverter's input near VCC/2. This establishes optimal operating point in the high-gain linear region, ensuring reliable crystal oscillation startup and stable amplitude across voltage and temperature - eliminating need for external bias components.

Can the 74AUP1Z04GM drive crystals above 1 MHz?

Yes - the 74AUP1Z04GM supports fundamental-mode crystals up to at least 100 MHz, as confirmed by propagation delay specs (0.7 ns min X1→X2 at 3.3 V). For frequencies >10 MHz, ensure external load capacitors C1/C2 are minimized to avoid excessive phase shift, and verify crystal drive level remains within manufacturer limits using series resistor R1.

How does the EN pin behave when left unconnected?

The EN pin has no internal pull-up or pull-down; leaving it floating risks undefined operation. When unused, tie EN to VCC to disable the driver (X1 pulled HIGH via RPU, X2 LOW, Y HIGH) - this places the device in low-power state with minimal ICC and prevents unintended oscillation or output contention.

Is the Y output synchronized to the crystal frequency?

No - Y is a buffered version of the X1 input signal, not a divided or phase-locked derivative of the oscillator output. Its timing follows X1 with typical tpd of 1.4–3.8 ns (VCC = 3.0–3.6 V, CL = 5–30 pF), making it suitable for system clock enable or interrupt generation, but not for direct substitution of the X2 crystal feedback signal.
