Product details
Overview
74AHC1G14GW,165 from Nexperia is a single-channel CMOS inverting Schmitt trigger with overvoltage-tolerant inputs (up to 5.5 V), operating across 2.0 V–5.5 V supply, delivering 12.8 ns max propagation delay at 3.3 V/15 pF, and specified for -40 °C to +125 °C. It enables robust signal conditioning in mixed-voltage sensor interfaces and noise-prone industrial control inputs.
For engineers reviewing the 74AHC1G14GW,165 datasheet, 74AHC1G14GW,165 pinout, 74AHC1G14GW,165 application, or 74AHC1G14GW,165 equivalent, this device serves as a precision waveform shaper in low-power edge-detection circuits, relaxation oscillators, and level-translating input buffers where hysteresis and rail-to-rail compatibility are critical.
Technical Context
The 74AHC1G14GW implements a true Schmitt-trigger transfer function with separate positive-going (VT+) and negative-going (VT-) thresholds-e.g., VT+ = 3.15 V and VT- = 1.35 V at VCC = 4.5 V-yielding 1.8 V hysteresis. Its input stage accepts voltages up to 5.5 V regardless of VCC, enabling direct interfacing with 5 V logic while powered from 3.3 V or lower.
It features symmetrical output drive (±8 mA at VCC = 4.5 V), CMOS-level input thresholds, and ultra-low static ICC (≤40 μA at 125 °C), making it suitable for battery-powered systems requiring stable switching despite slow-rising or noisy signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct integration into mixed-supply systems without level shifters. |
| Input Hysteresis (VH) | 1.8 V at VCC = 4.5 V - ensures clean, bounce-free transitions on slow or noisy inputs. |
| Propagation Delay (tpd) | 8.6 ns max at VCC = 4.5 V, CL = 15 pF - enables reliable timing in sub-100 MHz digital conditioning paths. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive multiple standard CMOS loads or small capacitive traces. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O stages. |
| Input Overvoltage Tolerance | 5.5 V absolute max - allows safe connection to 5 V buses while VCC = 3.3 V or 2.5 V. |
| ESD Protection | HBM >2000 V, CDM >1000 V - enhances field reliability in handling-sensitive assembly environments. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected | No internal bond; must remain unconnected or grounded per layout best practice. |
| 2 | Data input (A) | Schmitt-triggered inverter input; accepts 0–5.5 V regardless of VCC. |
| 3 | Ground (GND) | Reference return path for all signals and supply current; requires low-impedance PCB tie. |
| 4 | Data output (Y) | Inverted, buffered output with rail-to-rail swing and ±8 mA drive capability. |
| 5 | Supply voltage (VCC) | CMOS core supply; decoupling capacitor (100 nF) required within 3 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (2.0–5.5 V) | Enables single-device deployment across 2.5 V, 3.3 V, and 5 V subsystems without redesign. |
| Overvoltage-tolerant inputs | Eliminates external clamping diodes when interfacing legacy 5 V sensors to modern low-VCC MCUs. |
| Symmetrical output impedance | Ensures matched rise/fall times (<1.5 ns skew) for jitter-sensitive clock shaping applications. |
| High noise immunity (1.8 V hysteresis) | Rejects >1.8 V peak-to-peak noise on input lines, preventing false triggering in EMI-heavy environments. |
| Latch-up immunity (>100 mA) | Guarantees robustness against transient ground bounce or supply glitches in high-density layouts. |
Applications
| Waveform Shaping | Pulse Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G14GW,165 | TTL-compatible input thresholds (VIH ≈ 2.0 V), narrower 4.5–5.5 V supply range. | Better match for legacy 5 V TTL systems; unsuitable for sub-4.5 V operation. | Select when interfacing exclusively with 5 V logic families and no mixed-voltage translation is needed. |
| SN74LVC1G14DBVR | Lower VCC min (1.65 V), higher max output drive (±32 mA), but no overvoltage tolerance beyond VCC. | Preferred for ultra-low-voltage portable designs; requires external clamping for 5 V inputs. | Choose for battery-powered IoT nodes needing 1.8 V operation, provided input sources stay within VCC. |
Compared with 74AHCT1G14GW,165 and SN74LVC1G14DBVR, the 74AHC1G14GW,165 uniquely balances wide supply flexibility (2.0–5.5 V), input overvoltage safety, and industrial temperature support-making it optimal for mixed-rail industrial I/O where robustness and voltage translation coexist.

FAQ
Can the 74AHC1G14GW,165 be used with a 2.0 V supply and 5.0 V input signal?
Yes. Its inputs tolerate up to 5.5 V regardless of VCC, so a 5.0 V input is safe at VCC = 2.0 V. The output will swing rail-to-rail between 0 V and 2.0 V, preserving logic levels for downstream 2.0 V receivers. No external clamping is required.
What is the minimum load capacitance this device can drive reliably?
The 74AHC1G14GW,165 is characterized down to 15 pF load capacitance, with typical tpd = 3.2 ns at VCC = 5.0 V. Driving loads <10 pF may cause marginal edge ringing due to unterminated transmission line effects, but functionality remains intact per datasheet limits.
Does pin 1 (n.c.) require any PCB routing or thermal treatment?
No. Pin 1 is internally not connected and must remain unconnected on the PCB. It may be left floating or tied to GND for mechanical stability-no electrical function or thermal benefit is gained from either choice. Avoid routing signal traces beneath it.
How does hysteresis change with supply voltage?
Hysteresis (VH = VT+ − VT−) scales linearly with VCC: VH = 0.36 × VCC (typical). At VCC = 3.0 V, VH ≈ 1.08 V; at VCC = 5.5 V, VH ≈ 1.98 V. This maintains consistent noise margin percentage across the full supply range.
