Product details
Overview
XC7WH14DP,125 from Nexperia is a triple inverting Schmitt trigger IC in TSSOP8 package, providing three independent hysteresis-input buffers for noise-immune signal conditioning. It operates from 2.0 V to 5.5 V, delivers ±25 mA output drive, exhibits 3.2 ns typical propagation delay at 5 V, and supports industrial temperature range (−40 °C to +125 °C). It is used in waveform shaping, relaxation oscillators, and multivibrator circuits where slow or noisy inputs require clean digital transitions.
For engineers reviewing the XC7WH14DP,125 datasheet, XC7WH14DP,125 pinout, XC7WH14DP,125 application, or XC7WH14DP,125 equivalent, this device serves as a high-speed, low-power CMOS Schmitt trigger with verified hysteresis (VH = 0.45–1.6 V), precise threshold symmetry (VT+ = 3.85 V / VT− = 1.65 V at 5.5 V), and ESD robustness (HBM > 2000 V, CDM > 1000 V) for reliable edge detection in harsh environments.
Technical Context
The XC7WH14DP,125 implements three identical inverting Schmitt triggers using Si-gate CMOS technology, each with independently defined positive-going (VT+) and negative-going (VT−) input thresholds. Its hysteresis voltage (VH = VT+ − VT−) ranges from 0.3 V to 1.6 V depending on supply voltage, enabling stable switching against input noise up to ±1.2 V.
It features symmetrical output impedance, balanced tPLH/tPHL propagation delays (≤11.0 ns at VCC = 5.0 V, CL = 50 pF), and rail-to-rail output swing. Input clamping current is limited to ±20 mA, and static supply current remains below 40 μA across full temperature range, supporting low-power embedded timing and signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 5.5 V - Enables direct interface with 2.5 V, 3.3 V, and 5 V logic systems without level shifters. |
| Propagation Delay (tpd) | 3.2 ns (typ) at 5.0 V, CL = 15 pF - Supports >100 MHz signal conditioning in high-speed digital interfaces. |
| Hysteresis Voltage (VH) | 0.45 V to 1.6 V - Provides configurable noise margin; e.g., 1.2 V at 5.5 V ensures immunity to ≥600 mV peak-to-peak noise. |
| Output Drive (IO) | ±25 mA - Sufficient to directly drive multiple 74HC inputs or small capacitive loads (<50 pF) without buffering. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets IEC 61000-4-2 Level 2 requirements for board-level handling and system integration. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and extended-range power supplies. |
| Input Leakage (II) | ≤2.0 μA max - Ensures minimal loading on high-impedance sources such as RC timing networks or sensor outputs. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-lead, 3 mm body width, 0.5 mm lead length, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First inverting Schmitt trigger input - accepts slow-rising/falling signals; threshold hysteresis enables jitter-free output transitions. |
| 2 | 3Y | Third inverting Schmitt trigger output - provides clean HIGH/LOW logic levels referenced to VCC/GND with ±25 mA sink/source capability. |
| 3 | VCC | Positive supply rail - must be decoupled locally (e.g., 100 nF ceramic) due to fast switching-induced transient currents. |
| 4 | 1Y | First inverting Schmitt trigger output - electrically isolated from other outputs; usable as independent signal conditioner. |
| 5 | 2A | Second inverting Schmitt trigger input - functionally identical to Pin 1; allows three-channel parallel signal conditioning. |
| 6 | 3A | Third inverting Schmitt trigger input - shares same electrical specs as Pins 1 and 5; no crosstalk between channels. |
| 7 | GND | Ground reference - must be low-impedance return path; separate GND plane recommended for noise-sensitive applications. |
| 8 | 2Y | Second inverting Schmitt trigger output - matches Pin 4 and Pin 2 in VOH/VOL specs and drive strength. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tPLH ≈ tPHL), critical for duty-cycle stability in oscillator and clock-generation circuits. |
| Balanced propagation delays | Max 1.5 ns skew between channels ensures synchronized output edges across all three buffers in multi-phase timing applications. |
| CMOS input levels | Compatible with standard 3.3 V and 5 V logic families without external biasing; VIH/VIL thresholds scale with VCC. |
| High noise immunity | Guaranteed 1.2 V hysteresis at 5.5 V supply rejects common-mode noise and EMI-induced glitches on sensor or long-trace inputs. |
| Multiple package options | TSSOP8 (SOT505-2) offers proven manufacturability and thermal performance; pin-compatible with XC7WH14DC and XC7WH14GT for design flexibility. |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
Use Scenario: Converting slow, noisy analog sensor outputs (e.g., thermistor-based voltage dividers or magnetic pickup signals) into clean square waves for microcontroller capture. IC Role / Device Role / Timing Role: Inverting Schmitt trigger buffer - transforms ambiguous zero-crossings into deterministic logic transitions with controlled hysteresis. Use Value: Eliminates false triggering caused by <1.2 V noise; enables reliable edge detection without software debouncing or external RC filtering. |
Use Scenario: Generating continuous square-wave clock signals using two cascaded inverters and an RC feedback network (e.g., Fig. 12 in datasheet). IC Role / Device Role / Timing Role: Core oscillator element - one inverter provides gain, another provides phase inversion, third enables buffered output isolation. Use Value: Delivers stable frequency (e.g., 10–500 kHz) with <5% variation over temperature; eliminates need for dedicated oscillator ICs in cost-sensitive designs. |
| Monostable Multivibrator | Pulse Conditioning for Industrial I/O |
Use Scenario: Creating fixed-duration output pulses in response to momentary switch closures or external event triggers in PLC input modules. IC Role / Device Role / Timing Role: Triggered delay generator - uses internal hysteresis and external RC to define pulse width; third buffer isolates timing node. Use Value: Achieves precise 1–100 ms pulse widths with <10% tolerance across −40 °C to +125 °C, replacing discrete 555-based solutions. |
Use Scenario: Cleaning up mechanical contact bounce or EMI-corrupted signals from limit switches, encoders, or relay outputs in factory automation. IC Role / Device Role / Timing Role: Input signal conditioner - filters sub-millisecond transients while preserving true state transitions for real-time control logic. Use Value: Reduces firmware interrupt load by >90%; enables deterministic response within 11 ns of valid edge, improving system determinism. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Single-channel, same TSSOP5 package; lower drive (±24 mA), wider VCC range (1.65–5.5 V), but only one buffer per package. | Requires three devices for triple functionality; increases PCB area and BOM count; lacks channel-to-channel timing match. | Select when space-constrained single-channel operation suffices and inter-buffer skew is non-critical. |
| 74HC14PW,118 | Triple inverter in TSSOP14; higher propagation delay (105 ns typ at 4.5 V), wider supply (2–6 V), but no guaranteed hysteresis spec over temp. | Not qualified for +125 °C operation; hysteresis degrades above 85 °C, risking instability in automotive or industrial ambient conditions. | Select only for commercial-temp (0–70 °C) applications where ultra-low cost outweighs timing precision and thermal reliability. |
Compared with SN74LVC1G14DBVR and 74HC14PW,118, the XC7WH14DP,125 uniquely delivers triple-channel synchronization, guaranteed hysteresis across −40 °C to +125 °C, and sub-4 ns propagation at 5 V - making it optimal for compact, thermally demanding, multi-signal conditioning tasks.

FAQ
What is the minimum supply voltage required for guaranteed operation of XC7WH14DP,125?
The XC7WH14DP,125 is fully specified down to 2.0 V supply voltage per Table 6. At this level, VT+ is 1.9 V and VT− is 0.1 V (25 °C), ensuring functional hysteresis and output drive ≥±4 mA. Operation below 2.0 V may result in undefined thresholds or reduced noise margin.
Can XC7WH14DP,125 drive a 50 pF capacitive load at 5 V while maintaining timing specs?
Yes - the datasheet guarantees tpd ≤11.0 ns (max) at VCC = 5.0 V and CL = 50 pF (Table 9). Measured typical delay is 4.6 ns under those conditions, and output drive remains ±25 mA, ensuring clean edges without excessive ringing or undershoot.
How does the hysteresis voltage change with supply voltage?
VH scales linearly with VCC: it is 0.3 V at 3.0 V, 0.45 V at 4.5 V, and 0.5 V at 5.5 V (Table 8). This proportional relationship maintains consistent noise rejection ratio (VH/VCC ≈ 10%) across the operating range, simplifying design across mixed-voltage systems.
Is the TSSOP8 package (SOT505-2) lead-free and RoHS compliant?
Yes - Nexperia confirms the XC7WH14DP,125 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The SOT505-2 package uses lead-free matte tin terminal finish and halogen-free molding compound.
