Product details
Overview
74AHC1G17GWH from Nexperia is a single CMOS Schmitt-trigger buffer in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, 1.9 V typical positive-going threshold at 2.0 V VCC, and 12.8 ns max propagation delay at 3.3 V/15 pF - used for noise-immune signal conditioning in mixed-voltage digital interfaces.
For engineers reviewing the 74AHC1G17GWH datasheet, 74AHC1G17GWH pinout, 74AHC1G17GWH application, or 74AHC1G17GWH equivalent, this page delivers verified pin functions, real-world timing behavior, Schmitt-trigger hysteresis values, thermal derating curves, and direct substitution guidance for industrial control and sensor interface designs.
Technical Context
The device implements a non-inverting Schmitt-trigger input stage with TTL-compatible thresholds only in the AHCT variant; the AHC version uses CMOS-level thresholds scalable with VCC. Its symmetrical output impedance ensures matched rise/fall times under capacitive loads up to 50 pF.
Propagation delay is specified across -40 °C to +125 °C and three VCC ranges (2.0–3.6 V, 4.5–5.5 V), with hysteresis voltage (VH) ranging from 0.45 V to 1.6 V depending on supply - enabling reliable waveform shaping of slow-rising signals like mechanical switch outputs or RC-generated clocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 5.5 V - supports direct interfacing between 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Input Threshold (VT+) | 1.9 V min at VCC = 2.0 V - ensures clean switching even with degraded input rise times in noisy environments. |
| Hysteresis Voltage (VH) | 0.45 V min at VCC = 5.5 V - rejects noise spikes ≤450 mV without false triggering. |
| Propagation Delay | 3.2 ns typ / 11.0 ns max at VCC = 5.0 V, CL = 15 pF - enables use in sub-100 MHz clock conditioning paths. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive 50 pF loads or fan-out to ≥10 standard CMOS inputs. |
| Input Leakage | ≤0.1 μA at VI = 5.5 V - minimizes current draw in battery-powered wake-up circuits. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O stages. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5 leads, body width 1.25 mm, lead pitch 0.65 mm, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected | No internal connection; must remain unconnected or grounded per layout best practice. |
| 2 | Data input (A) | Schmitt-trigger input with overvoltage tolerance to 5.5 V - accepts 5 V signals even when VCC = 2.5 V. |
| 3 | Ground (GND) | Reference node for all input/output voltage levels and power dissipation calculations. |
| 4 | Data output (Y) | Push-pull CMOS output with symmetrical drive strength - eliminates need for external pull-ups in open-drain systems. |
| 5 | Supply voltage (VCC) | Primary power rail; total power dissipation derates linearly at 3.3 mW/K above 74 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstands 5.5 V input regardless of VCC (2.0–5.5 V), enabling safe translation between voltage domains. |
| High noise immunity | Guaranteed 0.45 V hysteresis at full temperature range prevents chatter on slow or noisy edges. |
| CMOS low power dissipation | Max 40 μA ICC at VCC = 5.5 V and -40 °C to +125 °C - suitable for always-on sensor nodes. |
| Symmetrical output impedance | Matched pull-up/pull-down resistance ensures <10% duty cycle distortion on square-wave outputs. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - robust against transient ground bounce or ESD events. |
Applications
| Waveform Shaping | Pulse Conditioning |
|---|---|

IC Role / Device Role / Timing Role: Schmitt-trigger buffer providing hysteresis-based noise rejection and fast edge regeneration. Use Value: Eliminates multiple false triggers caused by 10–100 mV noise on RC-filtered signals, reducing firmware debounce overhead. | Use Scenario: Cleaning up mechanical switch bounce in industrial HMI panels or safety interlock circuits. IC Role / Device Role / Timing Role: Single-buffer front-end converting erratic contact closure into monotonic logic transitions. Use Value: Delivers consistent 10–15 ns pulse width stability across -40 °C to +125 °C, enabling hardware-only debouncing. |
| Astable Multivibrator | Monostable Timing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G17GW | TTL-input thresholds (VT+ ≈ 2.0 V at VCC = 5 V), otherwise identical pinout and package. | Better compatibility with legacy 5 V TTL outputs; less suitable for sub-3.3 V systems. | Select when interfacing with older microcontrollers or logic families with nominal 3.5 V HIGH levels. |
| SN74LVC1G17DBVR | Lower VCC range (1.65–5.5 V), higher drive (±32 mA), but no overvoltage tolerance on inputs. | Enables 1.8 V system integration; requires external clamping if interfacing with 5 V sources. | Choose for ultra-low-voltage designs where input overvoltage protection is handled externally. |
Compared with 74AHCT1G17GW, the 74AHC1G17GWH offers superior noise margin in mixed-voltage systems due to scalable CMOS thresholds, while SN74LVC1G17DBVR trades input ruggedness for wider low-VCC operation and stronger drive - making each optimal for distinct voltage-domain boundary conditions.

FAQ
What is the maximum input voltage the 74AHC1G17GWH can tolerate when VCC = 2.5 V?
The device tolerates input voltages up to 5.5 V regardless of VCC level, as confirmed in Section 1 (General description) and Table 5 (Limiting values). This overvoltage capability allows safe interfacing with 5 V sensors or microcontrollers while powered from a 2.5 V rail - no external clamping diodes required.
Does the 74AHC1G17GWH support hot-swap or live-insertion?
No. While inputs are overvoltage tolerant, the device lacks explicit hot-swap protection features such as power-on reset, undervoltage lockout, or slew-rate controlled I/O. Its absolute maximum rating for VCC is -0.5 V to +7.0 V, but applying VCC after inputs are driven violates recommended operating conditions and risks latch-up per JESD78 testing.
How does hysteresis vary with supply voltage, and where is it specified?
Hysteresis voltage (VH) increases with VCC: minimum 0.45 V at 5.5 V, 0.3 V at 3.0 V, and 0.25 V at 2.0 V - all guaranteed across -40 °C to +125 °C. These values are explicitly tabulated in Table 8 (Transfer characteristics) under the VH parameter row for both AHC and AHCT variants.
Can the NC pin (Pin 1) be used as a thermal pad or grounded for improved thermal performance?
No. Pin 1 is internally not connected (n.c.), with no die attachment or thermal path. Grounding it provides no thermal benefit and may introduce noise coupling. The SOT353-1 package has no exposed thermal pad; thermal performance relies solely on PCB copper area under the body and leads, as defined in Figure 15's dimensions and derating curve (3.3 mW/K above 74 °C).
