74AHC1G17GVH Übersicht
A Schmitt-trigger buffer is a single-input, single-output logic gate whose input switching threshold includes deliberate hysteresis — the input trips at a higher voltage on the rising edge than on the falling edge. This suppresses noise-induced oscillation and produces a single, clean output edge even when the input signal is slow, noisy, or has significant ringing. Buffers (as opposed to inverters) simply re-create the input logic level with greater drive strength, isolating a sensitive source from a noisy load, or providing level translation between two voltage domains. The 74AHC1G17 sits within the logic IC hierarchy: logic gate -> combinational logic -> standard logic IC -> semiconductor IC.
Key features of the 74AHC1G17GVH include ±8 mA balanced output drive at 5 V, low quiescent current, fast propagation delay, and overvoltage-tolerant inputs. The SC-74A package measures only 2.9 x 1.5 x 1.0 mm with a gull-wing lead frame compatible with standard SMD assembly. The 1G family designation indicates a single-gate part optimized for footprint-sensitive designs where multi-gate packages would waste board area.
Typical applications include signal conditioning in industrial control, button/keyboard debouncing, level shifting between 3.3 V and 5 V rails, clock/pulse shaping in microcontroller I/O expansion, and general-purpose logic glue in mixed-signal systems. The wide 2.0-5.5 V operating range and CMOS/TTL input flexibility make it a versatile building block across consumer, industrial, and automotive subsystems. When designing with this part, ensure input edges are not faster than the datasheet-specified rise/fall limits and respect the absolute maximum VCC of 6 V to avoid latch-up.

Typische Anwendungen
74AHC1G17GVH ist geeignet für 6 Anwendungs: Mechanical Button / Switch Debouncing, 3.3 V to 5 V Logic Level Translation, Clock / Pulse Signal Conditioning, Microcontroller I/O Expansion and Isolation, Reset and Watchdog Signal Conditioning, Industrial Sensor Signal Buffering.
Mechanical Button / Switch Debouncing
The 74AHC1G17GVH is widely used to debounce mechanical push-buttons, toggle switches, and rotary-encoder contacts in industrial HMIs and consumer keypads. The Schmitt-trigger input hysteresis eliminates the rapid on/off chatter that mechanical contacts produce during closure, producing a single clean edge at the output. With VCC = 3.3 V or 5 V and ±8 mA output drive, it directly drives a microcontroller GPIO without additional buffering. Pair the input with a 10 kΩ / 100 nF RC network for software-free hardware debouncing in noisy factory environments.
Empfohlen
3.3 V to 5 V Logic Level Translation
The 74AHC1G17GVH's overvoltage-tolerant inputs (tolerant to 5.5 V regardless of VCC) make it a compact, single-bit level translator between a 3.3 V microcontroller and a 5 V peripheral. Power the part from the 3.3 V rail; drive inputs from the 5 V peripheral; outputs will swing rail-to-rail on the 3.3 V domain. This avoids the cost and complexity of dedicated translator ICs when only a handful of signals need shifting in mixed-voltage designs, such as 5 V sensors feeding a low-voltage host MCU on a factory sensor board.
Empfohlen
Clock / Pulse Signal Conditioning
In mixed-signal and timing-critical circuits, the 74AHC1G17GVH cleans up slow or ringing clock edges from long PCB traces, opto-isolators, or RC-coupled paths. The Schmitt-trigger input provides well-defined switching thresholds, and the push-pull CMOS output delivers sharp edges capable of driving 50 pF loads at 5 V within the datasheet's propagation delay. Use it to regenerate a degraded clock from a sensor, isolator, or RC oscillator before feeding the signal to a counter or PLL. The 2.0-5.5 V VCC range covers all common logic rails.
Empfohlen
Microcontroller I/O Expansion and Isolation
Place a 74AHC1G17GVH between a sensitive MCU output and a noisy load — such as a long cable, relay driver input, or motor-driver logic pin — to buffer and isolate the MCU from back-EMF and ESD events. The ±8 mA balanced output drive at 5 V is sufficient for short PCB traces and signal-path buffering. The part's small SC-74A footprint and single-gate design let engineers add isolation in tight board areas without dedicating a multi-gate IC that consumes more board space and quiescent current.
Empfohlen
Reset and Watchdog Signal Conditioning
Use the 74AHC1G17GVH to clean up a manual reset push-button, watchdog timer strobe, or supervisory circuit output before it reaches a processor's reset pin. The Schmitt-trigger action rejects the contact bounce of a front-panel reset button and the small glitches on a supervisory reset line, ensuring the processor only sees a single, clean reset pulse. Operating from the same 3.3 V or 5 V rail as the supervisor, the part integrates easily into any standard supervisory topology in industrial controllers.
Empfohlen
Industrial Sensor Signal Buffering
In industrial sensor front-ends — proximity sensors, Hall-effect devices, photo-interrupters — the 74AHC1G17GVH buffers and shapes the sensor's open-collector or analog-conditioned output before feeding it to a PLC digital input or MCU counter. The Schmitt-trigger input tolerates slow 10/90 % edges and rejects the high-frequency noise common on long factory-floor cable runs. The wide -40 C to +125 C operating range ensures reliability in unconditioned industrial enclosures, and the SC-74A package is rated for standard SMD assembly.

Wichtigste Unterscheidungsmerkmale
- 5 V-tolerant inputs when operated at lower VCC enables single-component level translation (vs. 74AHCT1G17GV)
- Smallest 5-pin footprint in the AHC1G17 family (vs. 74AHC1G17SE-7 (SOT-353/SC-88A))
- Same-brand suffix options for tape orientation without redesign (vs. 74AHC1G17GW)
Designhinweise
Place a 0.1 µF decoupling capacitor as close as possible to the VCC pin (pin 5) of the SC-74A package. For designs switching more than ~10 MHz or driving long PCB traces, add a bulk 1 µF to 10 µF capacitor on the same VCC net. Keep input traces short and away from switching noise sources; the Schmitt-trigger input will tolerate noise, but excessive ringing can exceed the absolute maximum input voltage of 5.5 V relative to GND.
The 74AHC1G17GVH draws very low quiescent current (typically a few µA), but the dynamic supply current scales with output load capacitance and frequency — estimate ICC_dynamic = CL × VCC × f × 10^-3 mA per Nexperia datasheet guidance. At 5 V with 50 pF load at 10 MHz, expect ~25 µA dynamic current. The overvoltage-tolerant input feature allows inputs to be driven above VCC up to 5.5 V without current paths, simplifying power-sequencing designs.
Do not exceed VCC = 6 V absolute maximum — latch-up can permanently damage the part. Pin 1 is sometimes marked NC for mechanical stability, but some Nexperia datasheet revisions use pin 1 as a no-connect or as a second GND in related 1Gxx families — verify against the package marking on the datasheet, not on a generic 1G family reference. For level translation, never drive the output above VCC; the push-pull output is not 5 V-tolerant when VCC = 3.3 V.
Compliance-Informationen
ROHS3 Compliant and REACH Unaffected per PartGenie summary; AEC-Q100 qualification status not stated by Nexperia in the verified web data — choose a Q-100 qualified variant (e.g., SN74AHC1G17QDRQ1) for automotive designs.
