74AHC1GU04GW,165

Overview

The Nexperia 74AHC1GU04 is a single unbuffered inverter featuring overvoltage tolerant inputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports input voltages up to 5.5 V. The device provides symmetrical output impedance and high noise immunity with CMOS low power dissipation. Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 (HBM > 2000 V) and JS-002 class C3 (CDM > 1000 V). It is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Overvoltage tolerant inputs enable use as translators in mixed voltage environments
• Symmetrical output impedance ensures balanced propagation delays
• High noise immunity combined with CMOS low power dissipation

Applications

• Linear amplifier circuits
• Crystal oscillator design
• Voltage translation between mixed voltage domains

Procurement Notes

Verify the specific package suffix against the required footprint, as the 74AHC1GU04 series includes TSSOP5 (GW), SC-74A (GV), and XSON5 (GZ). Confirm that the ordering suffix matches the exact thermal and mechanical requirements of the target PCB layout. Ensure compliance with RoHS and REACH regulations by checking the latest product database entries for chemical content declarations before finalizing procurement orders.

Selection Notes

Select this component when a single unbuffered inverter is required for signal inversion or linear amplification applications. The wide supply voltage range allows compatibility with both 3.3 V and 5 V logic systems. Consider the overvoltage tolerant inputs if interfacing with higher voltage signals without external level shifting. Verify that the unbuffered nature aligns with the application's drive requirements, as buffered alternatives may be needed for heavy capacitive loads.

Part Context

This part belongs to the Nexperia 74AHC family of high-speed CMOS logic devices. The 'U' designation indicates an unbuffered configuration, distinguishing it from buffered inverters like the 74AHC1G04. The 'GW' suffix specifically identifies the TSSOP5 plastic thin shrink small outline package. This family is designed for general-purpose digital and analog applications requiring low power consumption and high noise immunity.

Replacement Considerations

The 74AHC1G04 serves as a buffered alternative within the same logic family. For automotive applications, verify if an AEC-Q100 qualified variant such as the 74AHC1G04GW-Q100 is required. Cross-reference package dimensions carefully when substituting between GW, GV, and GZ packages due to differing physical footprints.
