Product details

Overview

74HC3G14GD,125 from Nexperia is a triple inverting Schmitt trigger IC operating from 2.0 V to 6.0 V, featuring CMOS-level inputs, 3 independent channels, hysteresis of 0.8–1.7 V (VCC = 6.0 V), and propagation delay as low as 13 ns at 6.0 V. It serves as a noise-immune signal conditioner in input interface stages of microcontroller systems, sensor front-ends, and oscillator circuits.

For engineers reviewing the 74HC3G14GD,125 datasheet, 74HC3G14GD,125 pinout, 74HC3G14GD,125 application, or 74HC3G14GD,125 equivalent, key selection criteria include input hysteresis voltage (VT+ / VT−), supply current under dynamic switching (ΔICC up to 410 µA), temperature range (−40 °C to +125 °C), and compatibility with TSSOP8 (SOT505-2) or VSSOP8 (SOT765-1) PCB footprints.

Technical Context

This device implements three independent Schmitt-trigger inverters in a single monolithic CMOS IC. Each channel converts slow-rising/falling analog-like inputs into clean digital outputs using asymmetric threshold voltages (e.g., VT+ = 3.46 V, VT− = 2.06 V at VCC = 6.0 V), enabling robust noise rejection in industrial control and sensor signal conditioning.

The logic function is strictly inverting (L → H, H → L), with input clamp diodes allowing safe interfacing to signals exceeding VCC when used with current-limiting resistors. Static input leakage remains ≤ ±1.0 µA across full temperature range, and output drive capability supports ±4.0 mA at VCC = 4.5 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 6.0 V - Enables direct use with 3.3 V and 5 V logic domains without level translation.
Hysteresis Voltage (VH)	0.80–1.70 V at VCC = 6.0 V - Provides ≥1.1 V noise margin for reliable edge detection in EMI-prone environments.
Propagation Delay (tpd)	13 ns typical at VCC = 6.0 V - Supports >30 MHz clock shaping in relaxation oscillators and pulse edge sharpening.
Input Thresholds (VT+, VT−)	3.00 V / 1.50 V (min) at VCC = 6.0 V - Ensures deterministic switching even with slow 10–100 ns input transitions.
Output Drive Current	±4.0 mA at VCC = 4.5 V - Sufficient to directly drive LED indicators, small capacitive loads (<50 pF), or next-stage CMOS inputs.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and outdoor sensor nodes.
ESD Protection	HBM >2000 V, CDM >1000 V - Reduces need for external TVS protection in board-level ESD test compliance (IEC 61000-4-2).

Pinout & Package

XSON8 (SOT996-2) package: plastic extremely thin small outline no-lead package; 8 terminals; body size 2.0 × 1.25 × 0.5 mm; exposed thermal pad; lead pitch 0.5 mm.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	Input A1, A2, A3	Three independent Schmitt-trigger inputs; each includes internal clamp diodes for overvoltage tolerance.
2, 5, 7	Output Y1, Y2, Y3	Inverted outputs with rail-to-rail swing; capable of sourcing/sinking 4 mA at 4.5 V.
4	GND	Dedicated ground reference for all three channels; must be low-impedance for stable hysteresis behavior.
8	VCC	Single supply rail shared across all inverters; decoupling capacitor (100 nF) required within 5 mm.

Key Features

Feature	Design Value
Triple independent Schmitt triggers	Enables simultaneous conditioning of three noisy sensor or switch inputs on one die-reducing BOM count and PCB area vs. discrete solutions.
Unlimited input rise/fall times	Validated operation with tr/tf >100 ns; eliminates timing uncertainty in RC-based timing circuits and mechanical switch debouncing.
CMOS-level input compatibility	VIH/VIL thresholds scale with VCC (e.g., VT+ ≈ 0.57×VCC), ensuring interoperability across 2.0–6.0 V supply rails without external biasing.
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events in industrial power supplies.
Low static power consumption	ICC ≤ 1.0 µA per input at VCC = 6.0 V - enables battery-powered applications with multi-year standby life (e.g., IoT wake-up sensors).

Applications

Waveform Shaping

Use Scenario: Converting slow, noisy sine-wave or triangle-wave signals from analog sensors into clean square waves for MCU capture timers.

IC Role / Device Role / Timing Role: Signal conditioning stage that rejects sub-threshold noise while preserving zero-crossing timing integrity.

Use Value: Eliminates software-based digital filtering overhead; reduces CPU load by delivering jitter-free edges directly to hardware timer inputs.

Use Scenario: Generating fixed-frequency clock signals in low-cost embedded systems where crystal oscillators are unnecessary.

IC Role / Device Role / Timing Role: Core timing element in a two-gate relaxation oscillator configuration with external R/C network.

Use Value: Achieves frequency stability of ±5% over −40 °C to +125 °C using only passive components-no crystal or trimmer required.

Monostable Multivibrator

Switch Debouncing

Use Scenario: Creating precise, temperature-stable one-shot pulses for interrupt generation or event synchronization in motor control feedback loops.

IC Role / Device Role / Timing Role: Inverter-based pulse stretcher triggered by mechanical or optical edge events.

Use Value: Delivers consistent 10–100 ms output pulse width independent of input bounce duration or ambient temperature drift.

Use Scenario: Cleaning contact bounce from pushbuttons, limit switches, or relay outputs before feeding to safety-critical logic.

IC Role / Device Role / Timing Role: Input filter stage that suppresses transients <100 ns while passing valid state changes.

Use Value: Guarantees single, glitch-free logic transitions-enabling deterministic state machine behavior without firmware debounce delays.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple Schmitt-trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LVC3G14GM,132	Lower VCC range (1.65–5.5 V); higher speed (tpd = 3.2 ns @ 3.3 V); smaller XSON8 (SOT833-1) footprint.	Better suited for high-speed 3.3 V FPGA I/O conditioning; not rated for 6.0 V operation or −40 °C to +125 °C extended temp.	Select when prioritizing speed and 3.3 V compatibility over wide-voltage flexibility and extended temperature range.
SN74LVC3G14DCUR	Texas Instruments part in VSSOP8 (SOT765-1); identical logic function; slightly higher ICC (max 10 µA vs. 1 µA).	Pin-compatible with 74HC3G14DC variant; same PCB land pattern; requires verification of TI's latch-up rating (JESD78 Class II Level A).	Choose for dual-sourcing in existing VSSOP8 designs where TI qualification documentation is mandated.

Compared with 74LVC3G14GM,132 and SN74LVC3G14DCUR, the 74HC3G14GD,125 offers superior voltage range (2.0–6.0 V) and lower quiescent current (≤1 µA), making it optimal for mixed-supply systems and ultra-low-power battery applications where extended temperature operation is critical.

FAQ

What is the maximum recommended supply voltage for continuous operation?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks exceeding the 250 mW total power dissipation limit in the XSON8 package and may degrade long-term reliability due to increased junction temperature and accelerated electromigration.

Can 74HC3G14GD,125 drive a 50 pF capacitive load at 10 MHz?

Yes. With CPD = 10 pF and typical tpd = 16 ns at VCC = 4.5 V, the device delivers clean transitions into 50 pF loads. Dynamic power at 10 MHz is ~2.3 mW (PD = CPD × VCC² × fi), well within its 250 mW Ptot rating, provided adequate PCB thermal relief is implemented beneath the exposed pad.

How does the input hysteresis behave across temperature?

Hysteresis voltage (VH = VT+ − VT−) remains stable from −40 °C to +125 °C: min 0.80 V, typ 1.40 V, max 1.70 V at VCC = 6.0 V. This tight specification ensures consistent noise margin across automotive and industrial operating conditions without calibration.

Is the XSON8 (SOT996-2) package compatible with standard reflow profiles?

Yes. The XSON8 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and supports peak reflow temperatures up to 260 °C. Standard lead-free reflow profiles with 60-second dwell above 217 °C are fully compatible when solder paste volume and stencil aperture are optimized for the 0.5 mm pitch and thermal pad.
