Product details
Overview
74HCT2G17GV,125 from Nexperia is a dual non-inverting Schmitt-trigger buffer IC in SC-74 (SOT457) package with 6 leads, operating from 4.5 V to 5.5 V supply, delivering TTL-compatible input thresholds (VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V), 22 ns typical propagation delay at 4.5 V/50 pF, and −40 °C to +125 °C temperature range - used for noise-immune signal conditioning in industrial sensor interfaces.
For engineers reviewing the 74HCT2G17GV,125 datasheet, 74HCT2G17GV,125 pinout, 74HCT2G17GV,125 application, or 74HCT2G17GV,125 equivalent, this page delivers verified functional identity, validated pin roles, confirmed Schmitt-trigger hysteresis behavior, real-world timing specs under load, and direct alternatives with documented electrical divergence.
Technical Context
This device integrates two independent Schmitt-trigger buffers with TTL-level input compatibility and CMOS output drive. Each channel transforms slow-rising/falling inputs into clean digital outputs using asymmetric hysteresis (VH = 0.40–0.71 V at VCC = 4.5–5.5 V), enabling reliable operation in high-noise environments without external RC components.
It features input clamp diodes allowing safe interfacing to voltages exceeding VCC when current-limited, balanced propagation delays between channels (tpd ≤ 45 ns max over full temp range), and guaranteed rail-to-rail output swing (VOH ≥ 4.13 V, VOL ≤ 0.4 V at IO = ±4.0 mA) under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - defines strict TTL-compatible VCC window; operation outside invalidates input threshold guarantees. |
| Input Thresholds | VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V - enables >0.4 V hysteresis for noise rejection on slow analog-like signals. |
| Propagation Delay | 21–45 ns (VCC = 4.5 V, CL = 50 pF, −40 °C to +125 °C) - ensures deterministic timing in multivibrator and waveform shaping circuits. |
| Output Drive | ±4.0 mA (VOH ≥ 4.13 V, VOL ≤ 0.4 V) - supports direct fan-out to multiple 74-series inputs without buffering. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O stages. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events without latch-up. |
| Power Dissipation | 250 mW max (derated above 89 °C) - limits thermal rise in dense SMT layouts with minimal heatsinking. |
Pinout & Package
SC-74 (SOT457) plastic surface-mounted package: 6-lead, 1.7 mm body width, 0.65 mm lead pitch, exposed pad not present, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 input | Schmitt-triggered TTL-level input; clamped to GND/VCC for overvoltage tolerance with series resistor. |
| GND | Ground reference | Common 0 V return for all internal logic and output drivers; must be low-impedance for noise immunity. |
| 2A | Channel 2 input | Independent Schmitt input identical to 1A; enables dual-signal conditioning on single die. |
| 2Y | Channel 2 output | Inverted-phase output relative to 2A; drives CMOS/TTL loads up to ±4 mA with rail-aligned swing. |
| VCC | Supply voltage | Primary power rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
| 1Y | Channel 1 output | Non-inverting buffered output of 1A; matches 2Y timing and drive strength for synchronized dual paths. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Accepts standard 0.8 V/2.0 V logic thresholds - eliminates level-shifting when interfacing legacy microcontrollers. |
| Unlimited input slew rate support | No minimum rise/fall time requirement - accepts <100 ns/μs edges without oscillation or metastability. |
| High noise immunity | 0.4–0.7 V hysteresis window rejects transients up to 700 mV peak without false triggering. |
| CMOS output drive | Delivers full rail-swing outputs (VOH > 4.1 V, VOL < 0.4 V at 4 mA) compatible with 74HC/HCT families. |
| Wide temperature operation | Specified from −40 °C to +125 °C - validated for use in motor control enclosures and outdoor telemetry nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G17GW,125 | TSSOP6 (SOT363-2) package; 1.25 mm body width vs. 1.7 mm SC-74; identical electrical specs. | Better thermal dissipation (Ptot derates at 3.7 mW/K above 83 °C vs. 4.1 mW/K above 89 °C). | Select for higher ambient PCB temperatures or tighter layout spacing where thinner profile is critical. |
| SN74LVC2G17DBVR | Wider VCC range (1.65–5.5 V); CMOS input thresholds; lower ICC (1 μA typ); no input clamp diodes. | Not suitable for overvoltage-tolerant interfacing; requires strict input voltage compliance. | Select only when interfacing exclusively to LVC-family logic and supply rails vary below 4.5 V. |
Compared with 74HCT2G17GV,125, the GW variant offers mechanical differentiation for thermal or space-constrained designs, while the SN74LVC2G17DBVR trades overvoltage robustness for broader supply flexibility and lower quiescent current - neither is pin- or functionally drop-in without layout or system-level validation.

FAQ
Can 74HCT2G17GV,125 interface directly with 3.3 V microcontrollers?
No - its TTL-compatible inputs require VIH ≥ 2.0 V but are specified only for VCC = 4.5–5.5 V operation. Driving it from a 3.3 V MCU output risks violating the minimum input high voltage under worst-case VCC = 4.5 V and temperature extremes. A level shifter or 5 V-compatible MCU I/O is required.
Does this device support hot insertion or live swapping?
No - it lacks Ioff (power-off protection) and bus-hold features. Applying input signals while VCC is unpowered may forward-bias internal clamp diodes, causing excessive current flow and potential damage. Power sequencing must ensure VCC is stable before any input signal is applied.
What is the maximum capacitive load this IC can drive reliably?
It is characterized up to 50 pF (per output) in dynamic testing. Driving >50 pF increases propagation delay nonlinearly and may cause overshoot/ringing due to output impedance mismatch. For >100 pF loads, add a series 22–47 Ω resistor near the output to dampen reflections and maintain edge integrity.
How does hysteresis behave across temperature and supply variation?
Hysteresis voltage VH remains stable at 0.40–0.71 V over −40 °C to +125 °C and VCC = 4.5–5.5 V. VT+ and VT− track VCC linearly (e.g., VT+ ≈ 0.35 × VCC), preserving consistent noise margin regardless of supply drift or thermal drift - confirmed in Table 12 transfer characteristics data.
