Product details
Overview
XC7WT14DP,125 from Nexperia is a triple inverting Schmitt trigger IC in TSSOP8 package, designed for noise-immune signal conditioning in industrial and automotive-adjacent control circuits. It delivers three independent hysteresis-enabled inverters with 0.35–1.6 V hysteresis voltage (VH), 1.0–9.0 ns propagation delay (tpd), and operation across -40 °C to +125 °C at 4.5–5.5 V supply.
For engineers reviewing the XC7WT14DP,125 datasheet, XC7WT14DP,125 pinout, XC7WT14DP,125 application, or XC7WT14DP,125 equivalent, key selection criteria include input threshold symmetry (VT+ = 2.0 V, VT− = 0.5–0.6 V), balanced output drive (±8 mA), ESD robustness (HBM >2000 V), and TSSOP8 thermal performance (Ptot = 250 mW @ ≤96 °C).
Technical Context
The XC7WT14DP,125 implements three independent CMOS Schmitt-trigger inverters using Si-gate technology, each with asymmetric input thresholds and rail-to-rail output swing. Its transfer characteristic provides fixed hysteresis (VH) independent of supply voltage across 4.5–5.5 V, enabling reliable waveform shaping under slow or noisy input transitions.
It operates as a level-shifting, jitter-free signal conditioner-converting analog-like inputs into clean digital outputs without external feedback components. The device supports relaxation oscillator configurations via external RC networks and maintains stable timing behavior over full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V logic systems and tolerates ±10 % supply variation. |
| Propagation Delay (tpd) | 1.0–9.0 ns @ CL = 15–50 pF - Enables high-speed edge regeneration for clock cleanup and pulse sharpening up to ~100 MHz. |
| Hysteresis Voltage (VH) | 0.35–1.6 V - Provides noise margin against EMI-induced glitches on slow-rising sensor or switch inputs. |
| Output Drive (IO) | ±8.0 mA - Sufficient to directly drive multiple 74HC inputs or small LEDs without buffering. |
| ESD Rating (HBM) | >2000 V - Meets IEC 61000-4-2 Level 2 requirements for board-level handling in manufacturing environments. |
| Operating Temperature | -40 °C to +125 °C - Supports under-hood, motor control, and industrial PLC applications without derating. |
| Input Capacitance (CI) | 10 pF - Minimizes loading on preceding stages in high-impedance sensor interfaces. |
Pinout & Package
TSSOP8 (SOT505-2) package: plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm lead pitch, 0.5 mm lead length, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 (1A, 2A, 3A) | Independent input terminals | Accept slow-rising/falling signals; each triggers its corresponding inverter with Schmitt action. |
| 2, 5, 7 (3Y, 1Y, 2Y) | Independent output terminals | Provide inverted, jitter-free digital outputs with rail-to-rail swing and ±8 mA drive capability. |
| 4 | GND | Reference ground node for all inputs, outputs, and internal circuitry; must be low-impedance connection. |
| 8 | VCC | Primary power supply input; decoupling capacitor (100 nF) required within 5 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tpLH ≈ tpHL), critical for duty-cycle preservation in oscillator and timing circuits. |
| High noise immunity | 0.35–1.6 V hysteresis window rejects transients ≤1.6 V peak-to-peak on input lines without false triggering. |
| Balanced propagation delays | ≤1 ns skew between channels ensures synchronized edge generation across all three inverters. |
| Low static current | ICC ≤ 40 μA @ VCC = 5.5 V - Reduces quiescent power in always-on monitoring nodes. |
| Multiple temperature grades | Qualified to -40 °C to +125 °C - Validated for extended-range operation without external thermal compensation. |
Applications
| Waveform Shaping in Noisy Environments | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting slow, noisy analog signals from mechanical switches or inductive sensors into clean square waves in factory automation panels. IC Role / Device Role / Timing Role: Signal conditioner and edge regenerator - transforms ambiguous transitions into deterministic logic levels with hysteresis-based noise rejection.

Use Value: Achieves frequency stability of ±5 % over temperature (-40 °C to +125 °C) without crystal or external timing ICs. |
| Monostable Multivibrator | Relaxation Oscillator Interface |
|

IC Role / Device Role / Timing Role: Pulse stretcher and timing generator - one inverter stage triggered by edge, with RC network defining pulse width. Use Value: Delivers consistent 10–100 ms output pulses independent of button press duration or contact resistance drift. |
Use Scenario: Driving variable-frequency oscillators in programmable power supply feedback loops or fan speed controllers. IC Role / Device Role / Timing Role: Adaptive timing core - third inverter enables external potentiometer or DAC to adjust RC time constant dynamically. Use Value: Enables real-time frequency tuning from 1 kHz to 100 kHz while maintaining jitter <5 % RMS across full range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC14APWR | Hex inverter (6 channels), lower VH (0.2–0.5 V), 3.3 V only (1.65–3.6 V VCC) | Requires level-shifting for 5 V systems; better suited for low-voltage portable designs. | Select when higher channel count and 3.3 V compatibility outweigh need for 5 V tolerance and wider hysteresis. |
| 74HC14D,653 | Hex inverter, identical pinout, VH = 0.9–1.7 V, but only rated to +85 °C (not +125 °C) | Lacks extended temperature qualification; unsuitable for under-hood or high-ambient industrial use. | Select only for cost-sensitive commercial-grade applications where ambient stays below 85 °C. |
Compared with SN74LVC14APWR and 74HC14D,653, the XC7WT14DP,125 uniquely combines triple-channel integration, 5 V operation, 125 °C rating, and wide hysteresis - making it optimal for space-constrained, thermally demanding signal conditioning tasks where reliability trumps channel count.

FAQ
What is the maximum recommended load capacitance for stable operation?
The XC7WT14DP,125 is characterized up to 50 pF load capacitance per output, with propagation delay increasing linearly beyond that point. For reliable timing in oscillator circuits, keep total load (including PCB trace and probe capacitance) ≤45 pF to maintain jitter <1 ns and avoid marginal oscillation startup.
Can this device operate with a 3.3 V supply?
No - the XC7WT14DP,125 is specified only for 4.5–5.5 V operation per Table 6. At 3.3 V, VIH/VIL thresholds become undefined, hysteresis collapses, and output drive falls below 1 mA, risking logic failure. Use SN74LVC14APWR instead for 3.3 V systems.
How does the hysteresis voltage change with temperature?
VH remains stable across temperature: 0.35–1.4 V at -40 °C to +125 °C (Table 8). The typical value is 1.0 V at 25 °C, decreasing slightly to 0.35 V at extremes - a design feature ensuring noise margin retention even at temperature limits.
Is there an exposed thermal pad on the TSSOP8 package?
No - the SOT505-2 (TSSOP8) package used for XC7WT14DP,125 has no exposed pad. Thermal dissipation relies solely on lead-frame conduction through pins 4 (GND) and 8 (VCC); PCB copper pour under the package is not electrically or thermally coupled.
