Nexperia USA Inc. 74LVC1GX04GW-Q100H

Overview

74LVC1GX04GW-Q100 from Nexperia is an automotive-grade crystal oscillator driver IC designed for Pierce oscillator configurations. It features dual outputs (X2 and Y), 1.65 V to 5.5 V supply operation, ±24 mA output drive at 3.0 V, IOFF-enabled partial power-down protection, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It drives fundamental-mode quartz crystals in engine control units and ADAS timing subsystems.

For engineers reviewing the 74LVC1GX04GW-Q100 datasheet, 74LVC1GX04GW-Q100 pinout, 74LVC1GX04GW-Q100 application, or 74LVC1GX04GW-Q100 equivalent, key selection criteria include crystal load capacitance tuning capability, IOFF leakage performance during system sleep states, propagation delay matching across temperature, and TSSOP6 package compatibility with high-density automotive PCB layouts.

Technical Context

This device implements a CMOS inverter-based crystal driver with two buffered outputs: X2 (inverted input) and Y (non-inverted output), enabling flexible oscillator feedback and clock distribution. Its IOFF circuit actively disables the Y output when VCC = 0 V, limiting backflow current to ≤±2 μA - critical for ISO 16750-compliant vehicle power sequencing.

The 74LVC1GX04GW-Q100 supports mixed-voltage interfacing: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), allowing direct connection to 5 V microcontrollers while powered from 3.3 V or 2.5 V rails. Propagation delays range from 0.3 ns (VCC = 4.5–5.5 V) to 6.5 ns (VCC = 1.65–1.95 V, −40 °C to +125 °C), with guaranteed monotonicity across voltage/temperature.

FAQ

What crystal load capacitance range is supported by the 74LVC1GX04GW-Q100?

The device supports standard Pierce oscillator configurations with load capacitances from 6 pF to 32 pF, determined by external C1/C2 values. The internal input capacitance is 5.0 pF, and design equations in Section 12.1.1 of the datasheet provide exact calculation methods using the crystal manufacturer's specified CL value and PCB stray capacitance.

Can the 74LVC1GX04GW-Q100 drive a 32.768 kHz watch crystal?

No - the 74LVC1GX04GW-Q100 is optimized for fundamental-mode crystals from 1 MHz to 50 MHz. Its input threshold and drive strength are not characterized for low-frequency tuning-fork crystals; use dedicated RTC oscillator ICs like PCF2129 for 32.768 kHz applications.

How does the IOFF function behave during VCC ramp-up?

IOFF remains active until VCC exceeds 0.5 V, at which point the Y output transitions from high-impedance to functional state with VOH/VOL specifications. This ensures no unintended clock pulses are generated during power-on sequencing, meeting ISO 11898-2 requirements for CAN transceiver initialization.

Is the X2 output inverted relative to X1, and can it be used as a clock signal?

Yes - X2 is the inverted output of the internal inverter stage and exhibits full rail-to-rail swing with matched drive strength to Y. It is intended for crystal feedback but may serve as a clock signal if phase inversion is acceptable; propagation delay from X1 to X2 is 0.3–4.5 ns, typically 0.5 ns faster than X1→Y.
