Product details
Overview
XC7SET14GV,125 from Nexperia is a single-channel CMOS inverting Schmitt trigger in SC-74A (SOT753) package, operating from 4.5 V to 5.5 V over -40 °C to +125 °C. It converts slow-rising/falling input signals into clean, jitter-free digital outputs with 0.4–1.6 V hysteresis, symmetric output drive (±8 mA), and 4.1–9.0 ns propagation delay at 15–50 pF load - used in waveform shaping and relaxation oscillators.
For engineers reviewing the XC7SET14GV,125 datasheet, XC7SET14GV,125 pinout, XC7SET14GV,125 application, or XC7SET14GV,125 equivalent, key selection criteria include Schmitt threshold symmetry (VT+ = 2.0 V, VT− = 0.5–0.6 V), TTL-compatible input levels, ESD robustness (HBM >2000 V, CDM >1000 V), and industrial temperature support up to +125 °C.
Technical Context
The XC7SET14GV,125 implements a single inverting buffer with hysteresis using Si-gate CMOS technology, enabling noise-immune signal conditioning without external feedback components. Its transfer characteristic defines distinct positive-going (VT+) and negative-going (VT−) thresholds, yielding a programmable hysteresis voltage (VH) of 0.4–1.6 V depending on supply voltage.
It operates with symmetrical output impedance and balanced propagation delays (tPLH ≈ tPHL), supports TTL-level inputs at VCC = 4.5–5.5 V, and maintains stable VIH/VIL margins across its full industrial temperature range. Static current consumption remains below 40 μA at VCC = 5.5 V and −40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | Inverting Schmitt trigger - provides noise-immune signal regeneration with built-in hysteresis |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and tolerant of ±0.5 V variation |
| Hysteresis Voltage (VH) | 0.4–1.6 V - ensures ≥300 mV noise margin between switching thresholds under all conditions |
| Propagation Delay | 4.1–9.0 ns - supports clean edge generation for clockless timing circuits up to ~100 MHz |
| Output Drive | ±8.0 mA - sufficient to directly drive 50 pF loads or interface with standard CMOS/TTL inputs |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 system-level robustness requirements |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, industrial control, and power-conversion environments |
Pinout & Package
XC7SET14GV,125 uses the SC-74A (SOT753) surface-mount package: plastic, 5-lead, 1.3 mm × 1.7 mm body, 0.95 mm lead pitch, and 0.6 mm height. Pin 1 is marked by a dot or beveled corner adjacent to the "g14" top-side marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | No-connect terminal | Internally unconnected; must remain floating or grounded per layout best practice - no routing required |
| A | Inverting input | TTL-compatible digital input accepting 0–5.5 V; triggers on rising/falling edges with hysteresis |
| GND | Ground reference | 0 V return path for supply and signal currents; requires low-inductance connection to PCB ground plane |
| Y | Inverted output | CMOS-compatible output sourcing/sinking ±8 mA; swings rail-to-rail within VCC and GND |
| VCC | Positive supply | Primary power pin; decoupling capacitor (100 nF ceramic) required within 3 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger hysteresis | Guaranteed 0.4–1.6 V window eliminates chatter on noisy or slow-transition inputs |
| Low static power | Max 40 μA ICC at +125 °C enables use in always-on industrial monitoring nodes |
| High noise immunity | Input thresholds shift <±50 mV over full temperature range, preserving noise margin stability |
| Robust ESD protection | HBM >2000 V and CDM >1000 V reduce field failure risk during handling and system integration |
| Industrial temperature grade | Specified performance from −40 °C to +125 °C supports deployment in motor drives and power supplies |
Applications
| Waveform Shaping | Pulse Generation |
|---|---|
|
Use Scenario: Converting distorted or slowly ramping analog sensor outputs (e.g., thermistor-based voltage ramps) into clean square waves for microcontroller capture. IC Role / Device Role / Timing Role: Signal conditioner that replaces RC + comparator circuits with single-device hysteresis-based edge sharpening. Use Value: Eliminates external components while maintaining sub-10 ns edge fidelity and rejecting >200 mV of common-mode noise. |
Use Scenario: Building compact, low-component-count astable multivibrators for LED blinkers or status indicators in space-constrained modules. IC Role / Device Role / Timing Role: Core inverter in a two-gate relaxation oscillator with external R-C feedback network. Use Value: Enables predictable frequency tuning via single resistor (e.g., 100 kΩ → ~1 kHz) without trimming or calibration. |
| Monostable Timing | Power-On Reset Conditioning |
|
Use Scenario: Generating fixed-duration pulses from push-button presses in industrial HMI panels where contact bounce must be suppressed. IC Role / Device Role / Timing Role: Input stage of a retriggerable monostable circuit that gates debounced transitions to downstream logic. Use Value: Provides inherent 300+ mV noise margin to reject switch transients, reducing need for additional RC filtering. |
Use Scenario: Cleaning up slow-rising or noisy power-supply monitor signals before feeding to a microcontroller's reset input. IC Role / Device Role / Timing Role: Threshold detector that asserts a clean, glitch-free reset pulse when VCC crosses valid operating range. Use Value: Ensures deterministic release of reset only after stable 5 V rail is confirmed, preventing brown-out lockup. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Wider VCC range (1.65–5.5 V); lower VT+ (1.4 V typ); VH = 0.2 V min; max tpd = 6.5 ns @ 5 V | Better suited for mixed-voltage systems (1.8/3.3 V), but reduced hysteresis lowers noise margin in 5 V industrial settings | Select when interfacing with sub-3.3 V logic or requiring lower supply flexibility; verify noise margin sufficiency for target environment |
| MC74VHC1G14DTT1G | Narrower temp range (−40 °C to +85 °C); higher ICC (100 μA max); VH = 0.3–1.2 V; SOT-23-5 package | Limited to commercial/industrial ambient zones; less suitable for under-hood or high-temp power electronics | Prefer for cost-sensitive consumer designs where +125 °C operation is unnecessary and SOT-23 footprint is preferred |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DTT1G, the XC7SET14GV,125 delivers superior thermal robustness (+125 °C), higher hysteresis (up to 1.6 V), and lower quiescent current at temperature - making it optimal for harsh-environment signal conditioning where reliability outweighs voltage flexibility.

FAQ
What is the function of the n.c. pin on XC7SET14GV,125?
The n.c. (no-connect) pin is internally unconnected and serves no electrical function. It must not be tied to VCC, GND, or any signal. PCB layout should leave it un-routed or optionally grounded for mechanical stability - never driven or loaded, as doing so may compromise ESD performance or thermal behavior.
Can XC7SET14GV,125 operate reliably at 3.3 V supply?
No - XC7SET14GV,125 is specified only for 4.5 V to 5.5 V operation per Table 6. At 3.3 V, VT+ and VT− thresholds fall outside guaranteed range, hysteresis collapses below 0.3 V, and output drive degrades below 4 mA. For 3.3 V systems, consider SN74LVC1G14DBVR instead.
How does the hysteresis voltage change with temperature?
VH remains stable across temperature: from −40 °C to +125 °C, VH stays within 0.35–1.6 V (min/max) at VCC = 4.5–5.5 V. Data Sheet Table 8 shows VT+ and VT− vary ≤±50 mV over full range, preserving ≥300 mV usable hysteresis - critical for consistent noise rejection in thermal cycling environments.
Is XC7SET14GV,125 suitable for automotive applications?
No - it is not AEC-Q100 qualified. While rated for −40 °C to +125 °C, it lacks automotive-specific stress testing, failure analysis, and PPAP documentation. For automotive use, select Nexperia's automotive-qualified variants like 74AUP1G14GW-Q100, which undergo full AEC-Q100 Grade 1 validation.
