Product details
Overview
74HC3G14DP-Q100 from Nexperia is a triple inverting Schmitt trigger IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with 2.0–6.0 V supply range and CMOS-level inputs. It provides sharp signal conditioning for slow-rising/noisy inputs in automotive timing and waveform shaping circuits, featuring 3 independent channels, hysteresis of 0.8–1.7 V (VCC = 6.0 V), and propagation delay as low as 13 ns.
For engineers reviewing the 74HC3G14DP-Q100 datasheet, 74HC3G14DP-Q100 pinout, 74HC3G14DP-Q100 application, or 74HC3G14DP-Q100 equivalent, this page delivers verified functional role, TSSOP8 package details, Schmitt-trigger transfer characteristics, automotive-grade thermal and ESD specs (HBM >2000 V), and real-world multivibrator design context - all confirmed from Nexperia's Rev. 4 product data sheet (Dec 2023).
Technical Context
This device implements three independent inverting Schmitt triggers with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors. Its hysteresis (VT+ − VT−) ranges from 0.30 V at 2.0 V VCC to 1.70 V at 6.0 V VCC, ensuring robust noise immunity against slow transitions and EMI in automotive environments.
The logic function is strictly inverting: L input yields H output, H input yields L output. Each channel operates with unlimited input rise/fall times and supports rail-to-rail output swing (VOH ≥ 5.68 V, VOL ≤ 0.26 V at VCC = 6.0 V, IO = ±5.2 mA), meeting JEDEC JESD7A and JESD8C standards for 2.0–6.0 V and 2.7–3.6 V operation respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Triple inverting Schmitt trigger - converts slow/noisy analog-like inputs into clean digital outputs with defined hysteresis |
| Supply Voltage Range | 2.0 V to 6.0 V - supports wide-battery automotive systems (e.g., 12 V nominal with load-dump transients) |
| Hysteresis Voltage (VH) | 0.80–1.70 V at VCC = 6.0 V - prevents chatter on marginal input thresholds in noisy under-hood environments |
| Propagation Delay (tpd) | 13 ns typical at VCC = 6.0 V - enables reliable timing in relaxation oscillators up to ~20 MHz |
| Input Clamping Current | ±20 mA - allows direct interface to overvoltage signals using external series resistors without damage |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive system-level ESD robustness requirements per AEC-Q100 |
| Operating Temperature | -40 °C to +125 °C - qualified for engine control, body electronics, and ADAS sensor front-ends |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 indicator located on lower left corner below marking code 'H14'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 (1A, 2A, 3A) | Data input | Three independent Schmitt-trigger inputs; each accepts CMOS-level signals and features internal clamp diodes |
| 2, 5, 7 (3Y, 1Y, 2Y) | Data output | Inverted outputs corresponding to pins 1/3/6; rail-to-rail swing with ±5.2 mA drive capability |
| 4 | GND | Ground reference (0 V) for all I/O and supply return; must be low-impedance for noise immunity |
| 8 | VCC | Positive supply rail; decoupling capacitor (100 nF) required near pin for stable Schmitt threshold operation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT3G14DP-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher propagation delay (21 ns typ @ 4.5 V) | Better suited for legacy 5 V TTL logic interfacing; less tolerant of sub-2 V input swings | Select when interfacing with older 5 V microcontrollers or op-amps with TTL output levels |
| SN74LVC3G14DCUR | Lower VCC range (1.65–5.5 V), smaller VSSOP8 package (SOT765-1), no AEC-Q100 qualification | Not qualified for automotive use; suitable for industrial or consumer portable designs requiring space savings | Choose for non-automotive applications needing footprint reduction and 1.8 V compatibility |
Compared with 74HC3G14DP-Q100, the 74HCT3G14DP-Q100 offers better 5 V TTL interoperability but sacrifices low-voltage operation; SN74LVC3G14DCUR reduces board area and supports 1.8 V logic but lacks automotive qualification and high-temp performance.

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. Continuous operation above 6.0 V risks parametric shift and reduced reliability, especially at high temperature. Nexperia specifies 6.0 V as the upper limit for guaranteed functionality and lifetime performance in automotive applications.
Can this IC interface directly with a 12 V sensor signal?
Yes - its input clamp diodes allow safe interface to signals up to VCC + 0.5 V. With a 5 V supply, a 12 V sensor output can be connected via a series current-limiting resistor (e.g., 10 kΩ limits input current to <0.7 mA). This avoids external level-shifting components while maintaining AEC-Q100 compliance.
How does hysteresis vary with supply voltage?
Hysteresis increases linearly with VCC: 0.30–1.00 V at 2.0 V, 0.60–1.40 V at 4.5 V, and 0.80–1.70 V at 6.0 V. This scaling ensures consistent noise margin across the full operating range - e.g., 1.7 V hysteresis at 6 V provides >28% of rail, matching typical automotive CAN/LIN bus noise floors.
Is the TSSOP8 package RoHS and REACH compliant?
Yes - the SOT505-2 (TSSOP8) package used for 74HC3G14DP-Q100 is fully RoHS-compliant (Pb-free terminations, homogeneous material restrictions met) and REACH-conformant, with no SVHC substances above threshold. Nexperia's declaration of conformity is publicly available on their website under product documentation.
