Product details
Overview
74HC2G17GV,125 from Nexperia is a dual non-inverting Schmitt trigger buffer in SC-74 (SOT457) package, featuring two independent channels with hysteresis thresholds (VT+ = 2.30 V, VT− = 1.13 V at VCC = 4.5 V), 2.0–6.0 V supply range, and −40 °C to +125 °C operation. It conditions slow or noisy input signals-such as those from mechanical switches or long PCB traces-in industrial sensor interfaces and power-on reset circuits.
For engineers reviewing the 74HC2G17GV,125 datasheet, 74HC2G17GV,125 pinout, 74HC2G17GV,125 application, or 74HC2G17GV,125 equivalent, this device is selected for robust signal conditioning where input rise/fall times are uncontrolled, noise immunity exceeds standard CMOS buffers, and dual-channel integration reduces board space in low-power digital subsystems.
Technical Context
The 74HC2G17GV,125 implements two independent Schmitt-trigger input stages feeding standard CMOS output buffers, enabling clean digital transitions from analog-like inputs. Each channel has separate input (1A, 2A) and output (1Y, 2Y) terminals, with shared VCC and GND rails.
Its transfer characteristic exhibits fixed hysteresis (VH = 1.13 V typical at VCC = 4.5 V), defined by distinct positive-going (VT+) and negative-going (VT−) thresholds. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Input hysteresis (VH) | 1.13 V typical at VCC = 4.5 V - rejects noise spikes up to ±565 mV on input signal without false triggering. |
| Propagation delay | 12 ns typical at VCC = 4.5 V, CL = 50 pF - enables reliable timing in sub-40 MHz digital signal conditioning paths. |
| Output drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or small capacitive loads (<50 pF). |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial control cabinets. |
| Input leakage current | ±1.0 μA max at VCC = 6.0 V - minimizes loading on high-impedance sources like RC timing networks. |
Pinout & Package
SC-74 (SOT457) plastic surface-mounted package: 6-pin, 1.7 mm body width, 0.95 mm height, lead pitch 0.95 mm. Pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data input (Channel 1) | Schmitt-trigger input accepting slow-rising/falling signals; clamped to VCC/GND via internal diodes. |
| GND | Ground reference | 0 V return path for both channels; must be low-impedance to maintain noise immunity. |
| 2A | Data input (Channel 2) | Independent Schmitt-trigger input; electrically isolated from 1A but shares same VCC/GND. |
| 2Y | Data output (Channel 2) | Inverted logic state of 2A with sharp edges; drives downstream CMOS/TTL loads. |
| VCC | Supply voltage | Power rail for both buffers; decoupling capacitor (100 nF) required within 5 mm of pin 5. |
| 1Y | Data output (Channel 1) | Non-inverting output synchronized to 1A; matches 2Y timing within 1 ns skew (typical). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Schmitt triggers | Enables simultaneous conditioning of two asynchronous signals (e.g., encoder A/B channels) in one 2.1 × 1.25 mm footprint. |
| Unlimited input rise/fall times | Eliminates need for external RC filtering; accepts inputs with >100 μs edge rates without metastability. |
| CMOS-level compatibility | Accepts 0–VCC input swing; outputs swing rail-to-rail (VOH ≥ 4.13 V, VOL ≤ 0.33 V at VCC = 4.5 V, IO = 4 mA). |
| High noise immunity | 1.13 V hysteresis and 2.0 V minimum input threshold reject common-mode noise up to 1.1 V peak-to-peak. |
| ESD protection | HBM >2000 V and CDM >1000 V - withstands handling and board assembly without external protection. |
Applications
| Industrial Switch Debouncing | Waveform Shaping for Sensor Outputs |
|---|---|
|
Use Scenario: Mechanical push-button or limit switch connected directly to microcontroller GPIO, generating contact bounce lasting 1–10 ms. IC Role / Device Role / Timing Role: Dual Schmitt trigger cleans both rising and falling edges; each channel processes one switch, eliminating software debouncing overhead. Use Value: Reduces firmware complexity and CPU load while guaranteeing deterministic 12 ns propagation delay per channel. |
Use Scenario: Analog-output temperature sensor with slow output slew rate (<1 V/ms) feeding into ADC reference clock enable path. IC Role / Device Role / Timing Role: Converts gradual voltage ramp into precise TTL/CMOS-compatible square wave with controlled edge timing. Use Value: Ensures clean clock enable assertion with jitter <1 ns, preventing ADC sampling errors due to ambiguous thresholds. |
| Astable Multivibrator Timing | Noise-Immune Power-On Reset |
|
Use Scenario: RC-based oscillator generating 10 kHz clock for LED blinker or status indicator using only passive components. IC Role / Device Role / Timing Role: One channel forms feedback loop with RC network; second channel buffers output to isolate load capacitance. Use Value: Stable oscillation frequency (±5% over temp) enabled by fixed hysteresis; no external comparators or op-amps needed. |
Use Scenario: Microcontroller reset line requiring clean, glitch-free assertion during 3.3 V rail ramp-up from 0 V to 3.3 V in <100 ms. IC Role / Device Role / Timing Role: Monitors VCC via resistor divider; Schmitt input prevents chatter during rail crossing of logic thresholds. Use Value: Guarantees single, monotonic reset pulse with 1.13 V hysteresis margin-no false resets during brown-out recovery. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G17GV,125 | TTL-compatible inputs (VIH = 2.0 V min), identical pinout and package | Better interoperability with legacy 5 V TTL logic; slightly higher ICC (20 μA max vs. 10 μA for HC) | Select when interfacing mixed 5 V TTL and CMOS systems; avoid if VCC < 4.5 V. |
| SN74LVC2G17DBVR | Lower VCC range (1.65–5.5 V), smaller X2SON-6 package (1.0 × 1.0 mm), 3.3 V optimized | Higher speed (7 ns tpd at 3.3 V), but reduced hysteresis (0.3 V typ) and narrower temp range (−40 °C to +85 °C) | Prefer for space-constrained 3.3 V designs where noise immunity <0.5 V suffices. |
Compared with 74HCT2G17GV,125, the 74HC2G17GV,125 offers superior noise margin at low VCC and lower static current, while SN74LVC2G17DBVR trades hysteresis depth for size and speed-making the HC variant optimal for wide-supply, high-noise industrial environments.

FAQ
What is the maximum input voltage allowed when VCC = 3.3 V?
The 74HC2G17GV,125 includes input clamp diodes that permit safe operation with input voltages up to VCC + 0.5 V (i.e., 3.8 V) when current is limited to ±20 mA. Exceeding this requires an external series resistor calculated per I = (VIN − VCC − 0.5 V)/R, ensuring current stays within rating.
Can this device drive a 100 pF load reliably?
Yes-the 74HC2G17GV,125 maintains specified propagation delay (≤22 ns) and output transition time (≤16 ns) at CL = 50 pF. At 100 pF, delay increases to ~30 ns and rise/fall times extend to ~25 ns, remaining functional for non-critical timing paths; add series termination if signal integrity degrades.
Is there a recommended bypass capacitor value and placement?
A 100 nF X7R ceramic capacitor is recommended between VCC (pin 5) and GND (pin 2), placed within 5 mm of the IC with minimal trace inductance. For systems with high di/dt noise, add a 1 μF bulk capacitor nearby to suppress low-frequency ripple.
Does the device support partial power-down operation?
No-74HC2G17GV,125 lacks Ioff protection. If VCC = 0 V while inputs are driven, current flows through input clamp diodes into GND, potentially disrupting upstream drivers. Always power VCC before applying input signals or use external isolation for hot-swap scenarios.
