Product details
Overview
74HCT2G17GW,125 from Nexperia is a dual non-inverting Schmitt trigger IC in TSSOP6 (SOT363-2) package, designed for noise-immune signal conditioning in digital interfaces. It features TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5 V), hysteresis voltage of 0.4–0.71 V, propagation delay of 21–45 ns (VCC = 4.5 V, CL = 50 pF), and operates across -40 °C to +125 °C. Used in wave shaping for industrial sensor interfaces where slow-rising signals require clean edge regeneration.
For engineers reviewing the 74HCT2G17GW,125 datasheet, 74HCT2G17GW,125 pinout, 74HCT2G17GW,125 application, or 74HCT2G17GW,125 equivalent, this page delivers verified functional identity, validated pin roles, confirmed Schmitt-trigger transfer characteristics (VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V), real-world timing behavior under load, and precise thermal/ESD specifications per JEDEC JS-001/JS-002.
Technical Context
This device implements two independent non-inverting buffers with Schmitt-trigger inputs, enabling robust conversion of slow or noisy analog-like digital signals into sharp, jitter-free logic-level outputs. Each channel provides input hysteresis (VH = 0.4–0.71 V) and clamp diodes allowing safe interfacing to voltages exceeding VCC via current-limiting resistors.
It supports dual supply domains: TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5 V) and CMOS-compatible output drive (VOH ≥ 4.13 V, VOL ≤ 0.33 V at IO = −4.0/+4.0 mA). Propagation delay and transition time are characterized across full temperature range (−40 °C to +125 °C) and supply (4.5–5.5 V), with dynamic power modeled via CPD = 10 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with 5 V TTL systems while maintaining noise margin and stable Schmitt thresholds. |
| Input Thresholds (VT+, VT−) | 1.20–1.90 V / 0.50–1.20 V - Defines hysteresis window for reliable noise rejection on slow-rising edges in industrial environments. |
| Propagation Delay (tpd) | 21–45 ns - Measured nA-to-nY at VCC = 4.5 V, CL = 50 pF; determines maximum usable frequency in pulse-shaping circuits. |
| Output Drive (VOH/VOL) | VOH ≥ 4.13 V @ −4.0 mA, VOL ≤ 0.33 V @ +4.0 mA - Guarantees logic-high integrity and low-voltage drop when driving multiple CMOS loads. |
| Operating Temperature | −40 °C to +125 °C - Validated for under-hood automotive modules, motor control feedback paths, and industrial PLC I/O stages. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Enables handling in standard assembly lines without special ESD controls beyond Class 2 requirements. |
| Power Dissipation | CPD = 10 pF - Enables accurate dynamic power calculation (PD = CPD × VCC² × fi × N) for thermal budgeting in dense PCB layouts. |
Pinout & Package
TSSOP6 (SOT363-2) plastic thin shrink small outline package, 6 leads, body width 1.25 mm, lead pitch 0.65 mm, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First Schmitt-trigger input - accepts slow/noisy signals; clamped diode enables overvoltage tolerance with series resistor. |
| 2 | GND | Digital ground reference - must be low-impedance connection to minimize switching noise coupling between channels. |
| 3 | 2A | Second Schmitt-trigger input - electrically isolated from 1A; supports independent signal conditioning paths. |
| 4 | 2Y | Output of second buffer - rail-to-rail CMOS output capable of sourcing/sinking 4 mA while maintaining VOH/VOL specs. |
| 5 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
| 6 | 1Y | Output of first buffer - identical electrical behavior to 2Y; enables dual-channel synchronization without external logic. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input levels | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5 V - Enables direct interface with legacy 5 V microcontrollers and logic families without level shifters. |
| Input hysteresis (VH) | 0.4–0.71 V - Suppresses chatter on slowly varying signals (e.g., mechanical switch bounce, thermistor ADC outputs). |
| Unlimited input rise/fall times | No minimum slew rate requirement - allows use with RC-filtered sensor outputs or long traces without timing uncertainty. |
| Latch-up immunity | >100 mA per JESD78 Class II Level B - Prevents destructive latch-up during transient overvoltage events in industrial settings. |
| Wide temperature operation | −40 °C to +125 °C - Qualified for engine control units, motor drives, and outdoor infrastructure electronics. |
Applications
| Industrial Sensor Interface | Motor Control Feedback |
|---|---|
|
Use Scenario: Conditioning analog-output Hall-effect sensor signals before feeding to MCU GPIO with weak internal pull-ups. IC Role / Device Role / Timing Role: Dual Schmitt trigger converts slow, noisy zero-crossing pulses into clean square waves synchronized to rotor position. Use Value: Eliminates false interrupts caused by EMI on 2 m cable runs; hysteresis rejects ±150 mV noise spikes without additional filtering. |
Use Scenario: Debouncing encoder quadrature A/B channel outputs in BLDC motor driver PCBs. IC Role / Device Role / Timing Role: Two independent non-inverting buffers regenerate edges while preserving phase relationship between channels. Use Value: Enables reliable direction detection at 50 kHz encoder rates; propagation delay matching (≤2 ns skew) prevents miscounting. |
| Automotive Body Control | Power Supply Sequencing Monitor |
|
Use Scenario: Converting slow-rising battery voltage monitor signals (e.g., from resistive divider) into digital enable flags. IC Role / Device Role / Timing Role: Single channel used as threshold detector; second channel reserved for future expansion or redundancy. Use Value: Hysteresis prevents oscillation during brown-out recovery; operates reliably down to 4.5 V supply with automotive-grade temp range. |
Use Scenario: Monitoring delayed power-good signals from DC-DC converters in multi-rail FPGA systems. IC Role / Device Role / Timing Role: Both channels condition separate PG signals (core & I/O rails), feeding OR-gated logic to reset controller. Use Value: Input clamp diodes tolerate overshoot during converter startup; balanced delays ensure deterministic sequencing window. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVR | CMOS-input (VIH = 0.7×VCC), wider supply (1.65–5.5 V), lower ICC (1 μA typ), but VH = 0.25 V only at 3.3 V. | Better for 3.3 V systems with ultra-low power budgets; insufficient hysteresis for noisy 5 V industrial lines. | Select when operating at 3.3 V with tight power constraints and clean signal sources. |
| MC74VHC2G17DTT1G | CMOS-input, higher speed (tpd = 7.5 ns @ 5 V), VH = 0.35 V, but only rated to +85 °C ambient. | Suitable for commercial-grade consumer devices needing faster edge regeneration; not qualified for under-hood use. | Choose for cost-sensitive 5 V applications below 85 °C where timing margin is critical. |
Compared with SN74LVC2G17DBVR and MC74VHC2G17DTT1G, the 74HCT2G17GW,125 uniquely combines TTL-level noise immunity, 125 °C operation, and proven industrial hysteresis-making it the only option qualified for harsh-environment dual-channel signal cleanup without derating.

FAQ
Can 74HCT2G17GW,125 interface directly with 3.3 V microcontrollers?
No-it is TTL-input compatible and specified for VCC = 4.5–5.5 V. Driving its inputs from 3.3 V logic may result in marginal VIH margin (2.0 V required vs. 3.3 V output), risking unreliable switching. Use level translators like TXB0104 or select 74LVC2G17 for true 3.3 V operation.
What is the maximum capacitive load this device can drive reliably?
It is characterized up to CL = 50 pF per output, with tpd and tt values guaranteed under that load. Driving >50 pF increases propagation delay nonlinearly and may cause ringing; for heavier loads, add a series resistor (22–47 Ω) near the output to dampen reflections.
Does this part support hot-swap or live-insertion?
No-its absolute maximum rating for VCC is +7.0 V, but no hot-swap protection circuitry (e.g., slew-rate limiting, back-drive blocking) is integrated. Applying VCC before GND or inserting while powered risks latch-up or ESD damage; always power-cycle before replacement.
How does input clamping affect design with overvoltage signals?
Clamp diodes allow safe interface to signals up to VCC + 0.5 V using a series current-limiting resistor (e.g., 10 kΩ for 12 V input → ~0.7 mA diode current). Exceeding ±20 mA clamping current risks permanent damage; resistor value must be calculated per IOK limit.
