74HC1GU04GV,125

Overview

The Nexperia 74HC1GU04GV,125 is a single unbuffered inverter from the HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range of -40 °C to +125 °C. The device utilizes a SC-74A (SOT753) surface-mount package with five leads. Static characteristics include high-level output voltages up to 5.81 V at 6.0 V supply and low leakage currents. Dynamic performance features propagation delays ranging from 18 ns to 105 ns depending on load capacitance and voltage.

Feature Summary

• Features input clamp diodes for interfacing with voltages exceeding VCC using current limiting resistors.
• Provides symmetrical output impedance and balanced propagation delays for consistent signal inversion.
• Offers high noise immunity and CMOS low power dissipation suitable for various digital applications.

Applications

• Linear amplifier circuits
• Crystal oscillator designs
• General-purpose signal inversion

Procurement Notes

Verify the specific ordering suffix '125' corresponds to the required temperature grade (-40 °C to +125 °C) and packaging format. Confirm that the SC-74A package dimensions align with the target PCB footprint. Ensure application requirements do not exceed the absolute maximum ratings defined in the datasheet.

Selection Notes

Select this component when a single-channel inverter is required with wide supply voltage flexibility between 2.0 V and 6.0 V. The unbuffered design allows for direct feedback connections in oscillator topologies. Verify that the input voltage levels remain within the specified limits relative to the chosen supply voltage.

Part Context

This part belongs to the 74HC1Gxx series of single-gate logic devices manufactured by Nexperia. The 'U' designation indicates an unbuffered configuration, distinguishing it from buffered variants like the 74HC1G04. The GV suffix identifies the SC-74A package type.

Replacement Considerations

Direct functional equivalents include the 74HC1G04GV,125 if buffering is acceptable. For identical unbuffered performance, verify pinout compatibility with other manufacturers offering single inverters in SOT753 packages.

FAQ

Can the 74HC1GU04 be used as a linear amplifier?

Yes, the datasheet specifies its use in linear amplifier configurations with appropriate biasing components.

What is the purpose of the input clamp diodes?

The clamp diodes allow the inputs to interface with voltages higher than VCC, provided current limiting resistors are used.
