74LVC1GX04GV-Q100H

Specialty Logic Overview

The Nexperia 74LVC1GX04GV-Q100H is a single-channel crystal driver (X-tal driver) designed for automotive applications, qualified to AEC-Q100 Grade 1. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V logic levels. It includes IOFF circuitry for partial power-down mode operation at output Y, preventing backflow current when powered down. Static characteristics include a maximum supply current of 4 μA and input leakage current of ±1 μA.

Specialty Logic Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• IOFF circuitry provides partial power-down mode operation at output Y
• Overvoltage tolerant inputs allow direct interface with TTL levels
• High noise immunity with ESD protection exceeding 2000 V (HBM)

Specialty Logic Applications

• Crystal controlled oscillator circuits
• Clock pulse generators
• Mixed 3.3 V and 5 V environments

Specialty Logic Procurement Notes

Verify the specific package variant required, as the GV suffix denotes the SC-74 (TSOP6) package. Confirm that the application requires the specific pinout configuration where Pin 1 is not connected and Pin 2 is Ground. Ensure the design accounts for the total power dissipation derating limits specified for the SC-74 package above 89 °C. Cross-reference the ordering information table to ensure the correct 12NC matches the desired temperature grade and packaging.

Specialty Logic Selection Notes

Select this component when a dedicated crystal driver with automotive reliability is required. The wide supply voltage range accommodates various logic families without additional level shifting. The inclusion of IOFF functionality makes it suitable for systems requiring low-power standby modes. Verify that the load capacitance requirements align with the internal input capacitance specifications provided in the static characteristics section.

Specialty Logic Part Context

This part belongs to the 74LVC1GX04-Q100 family of X-tal drivers manufactured by Nexperia. It is distinct from standard inverters like the 74LVC1G04 due to its specific optimization for driving quartz crystals. The GV package variant utilizes the SOT457 (SC-74; TSOP6) housing, which offers a small footprint suitable for space-constrained automotive PCB layouts.

Specialty Logic Replacement Considerations

The datasheet does not list specific substitute part numbers. Designers should verify compatibility with alternative crystal drivers from other manufacturers based on pinout, voltage range, and drive capability.
