Nexperia USA Inc. 74AHC1GU04GW,165

Overview

74AHC1GU04GW,165 from Nexperia is a single unbuffered CMOS inverter in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and operation across –40 °C to +125 °C. It serves as a level translator in mixed-voltage logic interfaces and enables crystal oscillator startup in low-power timing circuits.

For engineers reviewing the 74AHC1GU04GW,165 datasheet, 74AHC1GU04GW,165 pinout, 74AHC1GU04GW,165 application, or 74AHC1GU04GW,165 equivalent, this device is selected for voltage translation between 1.8 V/3.3 V and 5 V domains, low-noise signal inversion in sensor interface chains, and gate-based oscillator design where propagation delay stability and input overvoltage tolerance are critical.

Technical Context

This unbuffered inverter uses standard AHC-series CMOS architecture with no internal buffering stage, resulting in lower propagation delay but higher sensitivity to capacitive loading compared to buffered inverters. Its overvoltage-tolerant inputs allow direct connection to 5.5 V signals even when VCC is as low as 2.0 V - enabling bidirectional level shifting without external components.

The device exhibits symmetrical output drive (|IOH| ≈ |IOL|), supports dynamic operation up to 100 MHz at CL = 15 pF and VCC = 5.0 V, and maintains stable VIH/VIL thresholds across its full temperature range. Its static input leakage remains ≤2.0 μA at 5.5 V input and 125 °C ambient, supporting reliable operation in thermally demanding industrial control nodes.

FAQ

Is the 74AHC1GU04GW,165 pin-compatible with other SOT353-1 logic devices?

Yes - it shares identical SOT353-1 (TSSOP5) mechanical footprint and pinout (n.c./A/GND/Y/VCC) with other single-gate logic devices in Nexperia's AHC, LVC, and AUP families. However, electrical behavior differs: unbuffered architecture yields faster tpd but higher capacitive loading sensitivity than buffered equivalents like 74AHC1G04.

Can the 74AHC1GU04GW,165 be used in linear amplifier configurations?

Yes - the datasheet explicitly validates linear-mode operation (Fig. 11) with typical open-loop gain of 20 and unity-gain bandwidth of 5 MHz. Biasing requires external resistors (R1 ≥ 3 kΩ, R2 ≤ 1 MΩ) and load impedance >10 kΩ; output swing is limited to VCC – 1.5 V peak-to-peak centered at 0.5 × VCC.

What is the maximum capacitive load the 74AHC1GU04GW,165 can drive while maintaining specified propagation delay?

At VCC = 5.0 V, the device maintains tpd ≤ 7.0 ns (max) for CL = 50 pF per Table 8. Driving >50 pF increases tpd nonlinearly and may cause output waveform rounding or reduced noise margin; for >50 pF loads, add series termination or consider buffered alternatives like 74AHC1G04.

Does the 74AHC1GU04GW,165 require external ESD protection in system-level designs?

No - it integrates HBM >2000 V and CDM >1000 V ESD protection per JEDEC JS-001/JS-002, meeting IEC 61000-4-2 Level 2 (4 kV contact) system requirements. External TVS diodes are unnecessary unless the board-level environment exceeds ±8 kV contact discharge or involves cable-connected ports.
