What are the key features of 74LVC1GU04DCK?
- Single unbuffered CMOS inverter with linear gain region enabling use as a crystal oscillator amplifier at frequencies from 1 MHz to 50 MHz on a 1.65 V to 5.5 V supply
- 5-pin SC-70 package (2.0 mm × 2.1 mm) is among the smallest single-gate footprints, ideal for space-constrained logic-level conversion and signal-inversion on densely populated PCBs
- LVC-family CMOS process delivers approximately 3.8 ns propagation delay at 3.3 V with ±24 mA output drive, supporting fast signal edges in mixed 1.8 V / 3.3 V logic interfaces
What is 74LVC1GU04DCK used for?
The 74LVC1GU04DCK is commonly used as a single-gate crystal oscillator amplifier, clock buffer, or logic-level inverter in microcontroller, FPGA, and SoC designs where only one inversion stage is needed and board space is at a premium. Its wide 1.65 V to 5.5 V supply range and SC-70 package make it a versatile building block for signal conditioning, clock distribution fan-out, and pull-up level translation in IoT sensor nodes and portable consumer electronics.

Frequently Asked Questions
Why is the 74LVC1GU04DCK preferred over a buffered inverter for crystal oscillator circuits?
The unbuffered topology of the 74LVC1GU04DCK has a single CMOS gain stage that operates in its linear region, producing the high-gain analog amplification needed to sustain oscillation in a Pierce crystal circuit at frequencies from 1 MHz to 50 MHz. A buffered inverter has 3 cascaded stages that add excess phase shift and can prevent oscillator start-up, making the unbuffered 74LVC1GU04DCK the standard choice for crystal clock sources on 3.3 V MCU boards.
What supply voltage range and propagation delay does the 74LVC1GU04DCK support for mixed-voltage logic interfaces?
The 74LVC1GU04DCK operates from 1.65 V to 5.5 V, covering 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. Propagation delay is approximately 3.8 ns at 3.3 V and 5.5 ns at 1.8 V, allowing the device to translate and invert signals between different voltage domains at clock rates up to 100 MHz. The ±24 mA output current drive is sufficient to directly charge 50 pF load capacitances without an additional buffer in most PCB trace routing scenarios.
How does the 5-pin SC-70 package of 74LVC1GU04DCK compare to SOT-23-5 for dense PCB layouts?
The SC-70 package used by the 74LVC1GU04DCK measures 2.0 mm × 2.1 mm with a 0.65 mm pin pitch, occupying roughly 4.2 mm² of board area—approximately 40% less than a SOT-23-5 package at 7 mm². For a design with 8 inverter instances, switching from SOT-23-5 to SC-70 recovers approximately 22 mm² of PCB area, which is meaningful in compact wearables and IoT modules where board real estate is tightly constrained.
