Product details
Overview
74HCT2G17GV-Q100 from Nexperia is a dual non-inverting Schmitt trigger buffer IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and 22 ns typical propagation delay at VCC = 4.5 V/CL = 50 pF. It reshapes slow/noisy signals in engine control units and body electronics.
For engineers reviewing the 74HCT2G17GV-Q100 datasheet, 74HCT2G17GV-Q100 pinout, 74HCT2G17GV-Q100 application, or 74HCT2G17GV-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.71 V typ at VCC = 4.5 V), input clamp diodes enabling overvoltage-tolerant interfacing, automotive-grade thermal stability, and TSSOP6 (SOT457) package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent non-inverting Schmitt-trigger buffers with TTL-level input thresholds (VT+ = 1.58 V, VT− = 0.87 V at VCC = 4.5 V) and hysteresis of 0.71 V, enabling reliable signal conditioning of slow-rising or noisy waveforms without oscillation. Input clamp diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors.
It delivers balanced propagation delays (tpd = 21–45 ns across temperature) and transition times (tt = 6–22 ns), supports unlimited input rise/fall times, and maintains CMOS-level output drive (VOH ≥ 4.13 V, VOL ≤ 0.33 V at IO = ±4.0 mA) while drawing only 1.0–20.0 μA ICC across operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V automotive power rails and stable operation under load dump or cold-crank conditions. |
| Input Thresholds | VT+ = 1.58 V, VT− = 0.87 V (typ @ VCC = 4.5 V) - Provides 0.71 V hysteresis to reject noise up to ±350 mV on input signals. |
| Propagation Delay | 21 ns (typ), 45 ns (max @ −40 °C to +125 °C) - Enables reliable timing in pulse shaping and multivibrator circuits up to ~10 MHz. |
| Output Drive | VOH ≥ 4.13 V, VOL ≤ 0.33 V @ IO = ±4.0 mA - Sustains logic-high integrity driving 10+ 74HCT loads or capacitive traces up to 50 pF. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive ESD robustness requirements for in-vehicle assembly and field operation. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and transmission control module environments. |
| Power Dissipation | CPD = 10 pF - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting in compact modules. |
Pinout & Package
Supplied in SC-74 (TSOP6) plastic surface-mounted package (SOT457), 6-pin, 1.7 mm × 2.5 mm footprint, 0.65 mm pitch, with pin 1 indicator in lower-left corner below marking code "TV".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 input | TTL-compatible Schmitt-trigger input with internal clamp diodes; accepts voltages > VCC when series resistor limits current to < ±20 mA. |
| GND | Ground reference | 0 V return path for both channels; must be low-impedance to maintain noise immunity and output voltage accuracy. |
| 2A | Channel 2 input | Independent TTL-level Schmitt input; electrically isolated from 1A but shares same VCC/GND rails. |
| 2Y | Channel 2 output | CMOS-compatible non-inverted output; drives capacitive loads up to 50 pF with <22 ns transition time. |
| VCC | Supply voltage | Primary 4.5–5.5 V rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
| 1Y | Channel 1 output | Non-inverted buffered output synchronized to 1A; matches 2Y in drive strength and timing behavior. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C, including HTOL, TC, and ESD stress testing per JEDEC JESD47. |
| TTL-compatible input thresholds | VT+ = 1.58 V, VT− = 0.87 V @ VCC = 4.5 V - Ensures interoperability with legacy 5 V microcontrollers and sensors without level shifters. |
| Input clamp diodes | Enables direct interface to 12 V or 24 V signals using external current-limiting resistors, eliminating need for discrete protection components. |
| Unlimited input rise/fall times | Accepts arbitrarily slow edges (e.g., thermistor or potentiometer outputs) without metastability or false triggering due to Schmitt architecture. |
| Low static current | ICC ≤ 20.0 μA max @ VCC = 5.5 V and −40 °C to +125 °C - Supports always-on vehicle modules with strict quiescent power budgets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G17GW-Q100 | Same electrical specs, but in TSSOP6 (SOT363-2) package: 1.25 mm body width vs. 1.7 mm for SOT457. | Higher board-level density; tighter routing clearance required; identical thermal derating (4.1 mW/K above 89 °C). | Select when PCB real estate is constrained and reflow profile accommodates narrower pitch. |
| SN74LVC2G17QDCURQ1 | Lower VCC range (1.65–5.5 V), higher speed (tpd = 5.5 ns typ @ 3.3 V), no input clamp diodes. | Better suited for mixed-voltage 3.3 V systems; requires external clamping for >VCC interfaces; not qualified to AEC-Q100 Grade 1. | Choose only for non-automotive 3.3 V designs where ultra-low delay outweighs automotive qualification needs. |
Compared with 74HCT2G17GW-Q100, the GV variant offers wider PCB land pattern tolerance and slightly better thermal resistance; versus SN74LVC2G17QDCURQ1, it trades speed for guaranteed automotive qualification, input overvoltage resilience, and robustness in 5 V engine-bay environments.

FAQ
What is the maximum input voltage allowed when VCC = 5.0 V?
The input clamp diodes permit voltages up to VCC + 0.5 V (i.e., 5.5 V) continuously, provided input current remains within ±20 mA per JESD7A. For sustained overvoltage, a series resistor must limit peak current to ≤20 mA - e.g., a 1 kΩ resistor enables safe 12 V interface with 7 mA current.
Can this IC drive a 100 pF load reliably?
No - the datasheet specifies dynamic characteristics (tpd, tt) only for CL = 50 pF. Driving 100 pF increases propagation delay by ~30% and transition time by ~40%, potentially violating setup/hold timing in high-speed interfaces. Use a buffer stage or reduce trace capacitance to ≤50 pF.
Is there any difference in hysteresis between 74HC2G17GV-Q100 and 74HCT2G17GV-Q100?
Yes: at VCC = 4.5 V, the HC version has VH = 1.13 V (min), while the HCT version has VH = 0.71 V (typ). The HCT variant uses TTL-level thresholds optimized for 5 V systems, resulting in narrower hysteresis but better compatibility with legacy 5 V logic families.
Does this part support hot insertion or live swapping?
No - the device lacks Ioff (power-off protection) or partial-power-down capability. Applying input signals while VCC = 0 V may forward-bias internal protection diodes, causing excessive current flow and potential damage. Power sequencing must ensure VCC is stable before applying inputs.
