Product details
Overview
74LVC2G17GW,125 from Nexperia is a dual non-inverting Schmitt trigger buffer IC with 5 V tolerant inputs, designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is rated for -40 °C to +125 °C. It enables reliable level translation between 3.3 V and 5 V logic domains in industrial control interfaces.
For engineers reviewing the 74LVC2G17GW,125 datasheet, 74LVC2G17GW,125 pinout, 74LVC2G17GW,125 application, or 74LVC2G17GW,125 equivalent, this page provides verified functional identity, TSSOP6 package mapping, Schmitt-trigger hysteresis values (e.g., VH = 0.73 V typ at 3.0 V), IOFF leakage specs (<±2 μA), and validated alternatives for noise-immune waveform shaping.
Technical Context
This device implements two independent non-inverting Schmitt-trigger buffers with separate input thresholds (VT+ and VT−) and hysteresis (VH), enabling robust noise rejection on slow or noisy digital signals. Each channel supports rail-to-rail output swing and accepts inputs up to 5.5 V regardless of VCC level.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and multi-rail system design. Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with propagation delay as low as 1.0 ns at 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to 5 V sources while powered from 3.3 V or lower, supporting mixed-voltage translation. |
| Hysteresis Voltage (VH) | 0.73 V typical at VCC = 3.0 V - Provides noise margin >200 mV for reliable edge detection on degraded waveforms. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple LVC loads or moderate capacitive traces without buffering. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Prevents disruptive current flow into powered-down sections during partial power-down sequencing. |
| Propagation Delay (tpd) | 1.0 ns min / 5.4 ns max at VCC = 4.5–5.5 V - Ensures timing predictability in high-speed clock/data conditioning paths. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and extended-temperature embedded controllers. |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2); 6 leads; body width 1.25 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A - Channel 1 input | Schmitt-trigger input accepting 0–5.5 V; enables noise-immune signal acquisition from legacy or noisy sources. |
| 2 | GND - Ground reference | Common return path for both channels; must be low-impedance to maintain hysteresis stability and noise immunity. |
| 3 | 2A - Channel 2 input | Independent Schmitt input; allows dual-channel waveform shaping without cross-talk or shared threshold drift. |
| 4 | 2Y - Channel 2 output | Non-inverting buffered output with rail-to-rail swing; drives downstream logic or analog comparators. |
| 5 | VCC - Supply voltage | Single supply powering both buffers; IOFF activates automatically when VCC = 0 V to isolate outputs. |
| 6 | 1Y - Channel 1 output | Matched-output channel with identical timing and drive specs; supports parallel signal conditioning paths. |
Key Features

Applications
| Industrial Encoder Interface | Automotive Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Quadrature signals from rotary encoders exhibit slow edges and EMI-induced jitter in factory automation cabinets. IC Role / Device Role / Timing Role: Dual Schmitt trigger buffers reshape A/B phase signals, restoring clean square waves before MCU quadrature decoder input. Use Value: Hysteresis (0.73 V typ at 3.0 V) rejects sub-microsecond noise spikes, eliminating false counts without software debouncing overhead. |
Use Scenario: Analog sensor outputs (e.g., throttle position) digitized via open-collector comparators generate slow, noisy transitions in engine bays. IC Role / Device Role / Timing Role: Converts comparator outputs into fast, rail-to-rail CMOS logic levels compatible with automotive microcontroller GPIOs. Use Value: 5 V tolerant inputs accept comparator outputs referenced to 5 V supplies, while VCC = 3.3 V matches MCU I/O voltage. |
| USB Hub Power-Sequence Monitoring | Programmable Logic I/O Expansion |
|
Use Scenario: USB hub power rails sequence up asynchronously; status lines require glitch-free assertion before enumeration. IC Role / Device Role / Timing Role: Buffers and cleans reset/status signals from discrete MOSFET supervisors during multi-rail power-up sequences. Use Value: IOFF ensures no current flows from active 5 V status lines into unpowered 3.3 V monitoring logic during staggered startup. |
Use Scenario: FPGA I/O banks configured for 1.8 V logic must interface with 3.3 V peripheral control lines (e.g., display enable, SD card detect). IC Role / Device Role / Timing Role: Translates and conditions control signals between mismatched voltage domains while preserving edge timing. Use Value: Propagation delay variation <1.5 ns across VCC (1.65–5.5 V) prevents skew-induced setup/hold violations in synchronous control paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum input voltage the 74LVC2G17GW,125 can tolerate when VCC = 1.8 V?
The device accepts inputs up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Section 2 (Features). This overvoltage tolerance enables safe interfacing with 5 V sources while operating from 1.8 V, eliminating external clamping diodes or resistors in mixed-voltage designs.
Does the 74LVC2G17GW,125 support hot-swap insertion in live backplanes?
Yes-the IOFF circuitry disables outputs when VCC = 0 V, limiting backflow current to ±2 μA max (Table 7). This meets IEC 61000-4-2 system-level ESD robustness requirements and prevents bus contention during live insertion, provided GND connects first and VCC last in the mating sequence.
How does the Schmitt trigger hysteresis change with supply voltage?
Hysteresis voltage (VH) scales with VCC: it is 0.49 V typ at 1.8 V, 0.73 V typ at 3.0 V, and 1.02 V typ at 5.5 V (Table 11). This proportional relationship maintains consistent noise margin relative to logic swing, ensuring reliable operation across the full 1.65–5.5 V supply range.
Can the 74LVC2G17GW,125 drive a 50 pF load at 10 MHz without signal degradation?
Yes-dynamic characteristics show tpd ≤ 7.1 ns and tr/tf ≤ 2.5 ns at VCC = 3.0–3.6 V driving 50 pF (Table 10). At 10 MHz (100 ns period), this introduces <7% timing uncertainty, well within setup/hold margins for standard CMOS receivers, provided trace impedance is controlled.
