Product details
Overview
74AHCT1G04GW,165 from Nexperia is a single-channel TTL-input inverter in TSSOP5 (SOT353-1) package, operating from 4.5 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and propagation delay as low as 3.4 ns (typ.) at 5 V/15 pF. It serves as a level-translating logic buffer in mixed-voltage digital subsystems such as industrial I/O interfaces and microcontroller peripheral conditioning.
For engineers reviewing the 74AHCT1G04GW,165 datasheet, 74AHCT1G04GW,165 pinout, 74AHCT1G04GW,165 application, or 74AHCT1G04GW,165 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), guaranteed operation from –40 °C to +125 °C, output drive capability of ±8 mA, and compatibility with 5 V CMOS/TTL logic families in space-constrained PCB layouts.
Technical Context
The 74AHCT1G04GW,165 implements a single unbuffered inverting gate with TTL-level input switching thresholds and rail-to-rail CMOS output swing. Its input stage accepts voltages up to 5.5 V independent of VCC, enabling safe interfacing between 3.3 V controllers and 5 V peripherals without external level shifters.
It features balanced rise/fall times, symmetrical output impedance (~20 Ω typical), and latch-up immunity exceeding 100 mA per JESD78 Class II Level A. The device is characterized for full industrial temperature range (–40 °C to +125 °C) and supports dynamic loading up to 50 pF with sub-10 ns propagation delay across its operating voltage window.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL and CMOS systems; not functional below 4.5 V. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - Matches legacy TTL logic families; eliminates need for external biasing on input lines. |
| Propagation Delay | 3.4 ns (typ.) at 5 V/15 pF - Enables reliable timing in high-speed control paths up to ~100 MHz toggle rate. |
| Output Drive | ±8 mA at VCC = 5 V - Sufficient to directly drive multiple 74-series inputs or small capacitive loads (< 30 pF). |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and power supply monitoring circuits. |
| Input Overvoltage Tolerance | Up to 5.5 V regardless of VCC - Allows hot-swap-safe connection to 5 V buses while powered from lower supplies (e.g., 4.5 V). |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets IEC 61000-4-2 Level 2 requirements for board-level robustness. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, body width 1.25 mm, 0.65 mm pitch, exposed pad not present, pin 1 marked by notch or dot in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | No-connect terminal | Physically present but internally unconnected; must remain floating or grounded per layout best practice - no routing required. |
| VCC | Positive supply rail | Primary power input; requires local 100 nF ceramic decoupling within 3 mm of pin to suppress switching noise. |
| A | Inverting logic input | Single-ended digital input accepting TTL thresholds; overvoltage tolerant to 5.5 V even when VCC = 4.5 V. |
| GND | Ground reference | Return path for supply and signal currents; must connect to low-impedance system ground plane. |
| Y | Inverted logic output | CMOS-compatible push-pull output; drives HIGH to VCC and LOW to GND with matched rise/fall characteristics. |
Key Features
| Feature | Design Value |
|---|---|
| TTL input compatibility | Guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V across full temperature range enables direct interface with legacy 74LS/74F logic without pull-ups or translators. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC value, simplifying mixed-supply domain bridging in modular PCB designs. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduced signal distortion on transmission lines. |
| High noise immunity | Input hysteresis margin > 1.2 V (VCC = 5 V) rejects EMI-induced glitches in noisy industrial environments. |
| Extended temperature rating | Specified from –40 °C to +125 °C supports deployment in engine control units, motor drives, and outdoor telecom equipment. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | CMOS input thresholds (VIH = 70% VCC), wider supply range (1.65–5.5 V), lower ICC (max 10 μA) | Better suited for battery-powered 3.3 V systems; lacks TTL input compatibility | Select when interfacing with modern low-voltage MCUs and power efficiency is critical. |
| MC74VHC1GT04DTT1G | Wider supply range (2.0–5.5 V), CMOS inputs, higher output drive (±8 mA @ 3.3 V), same TSSOP5 footprint | Compatible with both 3.3 V and 5 V domains but requires external pull-up for TTL-like behavior | Choose when dual-voltage flexibility is needed and input threshold customization is acceptable. |
Compared with SN74LVC1G04DBVR and MC74VHC1GT04DTT1G, the 74AHCT1G04GW,165 uniquely guarantees TTL input compatibility at 5 V while maintaining industrial temperature range and overvoltage tolerance - making it irreplaceable in legacy-system upgrades where signal integrity and backward compatibility are non-negotiable.

FAQ
Is the 74AHCT1G04GW,165 pin-compatible with the 74AHC1G04GW?
Yes - both share identical TSSOP5 (SOT353-1) pinout and mechanical footprint. However, the 74AHCT1G04GW uses TTL input thresholds (VIH ≥ 2.0 V), while the 74AHC1G04GW uses CMOS thresholds (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping them requires verifying input source compatibility.
Can the 74AHCT1G04GW,165 operate at 3.3 V supply?
No - the 74AHCT variant is specified only for 4.5 V to 5.5 V supply. At 3.3 V, input thresholds become undefined and output drive collapses. For 3.3 V operation, use the 74AHC1G04GW or 74LVC1G04 variants instead.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF load capacitance with guaranteed propagation delay (≤ 10.0 ns at VCC = 5 V). For loads > 30 pF, add series termination (22–33 Ω) near the output to prevent ringing; total trace + load capacitance should remain ≤ 60 pF for stable 100 MHz toggling.
Does the 'n.c.' pin require PCB routing or grounding?
No - the n.c. (pin 1 in TSSOP5) is internally unconnected. It may be left floating, grounded, or tied to VCC per board-level ESD best practices, but no electrical function is affected. Do not route signals to it; maintain standard keep-out zone around the pad.
