Product details
Overview
XC7SH14GV,125 from Nexperia is a high-speed Si-gate CMOS inverting Schmitt trigger in SC-74A (SOT753) package with 5 leads, operating from -40 °C to +125 °C. It converts slow-rising/falling input signals into clean, jitter-free digital outputs using hysteresis (VT+ = 3.15 V, VT− = 1.35 V at VCC = 4.5 V), enabling reliable waveform shaping in noisy environments such as industrial sensor interfaces and microcontroller reset conditioning.
For engineers reviewing the XC7SH14GV,125 datasheet, XC7SH14GV,125 pinout, XC7SH14GV,125 application, or XC7SH14GV,125 equivalent, this device is selected for its symmetrical output impedance (enabling balanced rise/fall times), low ICC (≤40 μA at VCC = 5.5 V), ESD robustness (HBM >2000 V, CDM >1000 V), and guaranteed operation across extended temperature range - critical for automotive-adjacent control logic and industrial timing circuits.
Technical Context
The XC7SH14GV,125 implements a single-channel inverting buffer with Schmitt-trigger input hysteresis, defined by separate positive-going (VT+) and negative-going (VT−) thresholds. Its transfer characteristic ensures noise immunity by rejecting input fluctuations within the hysteresis band (VH = 1.8 V typical at VCC = 4.5 V).
It operates with CMOS-compatible input levels and delivers rail-to-rail output swing (VOH ≥ 3.70 V, VOL ≤ 0.55 V at IO = ±8 mA, VCC = 4.5 V), supporting direct interfacing with 3.3 V and 5 V logic families. Propagation delay is specified down to 3.2 ns (typical, CL = 15 pF, VCC = 5.0 V), with power dissipation capacitance CPD = 12 pF enabling accurate dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - supports dual-voltage system interoperability (e.g., 3.3 V MCU I/O with 5 V legacy peripherals) |
| Input Thresholds (VCC = 4.5 V) | VT+ = 3.15 V, VT− = 1.35 V - 1.8 V hysteresis enables rejection of up to ±900 mV noise on signal lines |
| Propagation Delay (CL = 15 pF) | 3.2 ns (typ), 11.0 ns (max) - ensures sub-10 ns timing margin for 50 MHz clock edge conditioning |
| Output Drive (VCC = 4.5 V) | IOH/IO L = ±8 mA - sufficient to drive 10 pF load with <10 ns edge rate and fan-out of ≥10 standard CMOS inputs |
| Supply Current (VCC = 5.5 V) | ICC ≤ 40 μA (max, −40 °C to +125 °C) - enables ultra-low-power wake-up detection in battery-backed systems |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 for board-level ESD resilience without external protection |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood industrial control modules and motor drive feedback conditioning |
Pinout & Package
XC7SH14GV,125 uses the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, pitch 0.95 mm, with pin 1 indicator located below marking "f14" at lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - must be left floating or grounded per layout best practice; no electrical function |
| 2 | A | Inverting Schmitt trigger input - accepts slow analog-like transitions (e.g., thermistor voltage ramps) and digitizes them with hysteresis |
| 3 | GND | Ground reference (0 V) - serves as return path for supply and signal currents; requires low-impedance PCB plane connection |
| 4 | Y | Inverted, jitter-free digital output - provides clean HIGH/LOW transitions synchronized to input crossing VT+ or VT− |
| 5 | VCC | Positive supply (2.0–5.5 V) - powers internal CMOS circuitry; requires local 100 nF decoupling near pin |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tpLH ≈ tpHL), reducing duty-cycle distortion in clock regeneration applications |
| High noise immunity | 1.8 V hysteresis at 4.5 V supply rejects common-mode noise spikes up to ±900 mV without false triggering |
| Low power dissipation | ICC ≤ 40 μA max over full temperature range - allows continuous monitoring in always-on subsystems with <200 μW static power |
| CMOS input levels | Accepts 0–VCC logic swings directly - eliminates level-shifter requirements when interfacing with same-supply MCUs or sensors |
| Balanced propagation delays | tpLH and tpHL differ by <15% - preserves pulse width integrity in monostable/multivibrator timing networks |
Applications
| Waveform Shaping | Astable Multivibrator |
|---|---|
|
Use Scenario: Converting noisy analog sensor outputs (e.g., potentiometer wiper voltage, thermistor divider) into clean square waves for microcontroller ADC sampling or GPIO edge detection. IC Role / Device Role / Timing Role: Inverting Schmitt trigger acting as noise-immune signal conditioner - transforms slow monotonic input changes into sharp, jitter-free digital transitions. Use Value: Eliminates software debouncing and reduces firmware interrupt latency by delivering deterministic, glitch-free edges even with >1 μs input slew rates. |
Use Scenario: Building compact, low-component-count oscillator circuits for LED flashers, tone generators, or system heartbeat signals. IC Role / Device Role / Timing Role: Core inverter in RC feedback loop - provides gain and hysteresis required for self-sustaining oscillation without external biasing components. Use Value: Enables stable frequency generation (e.g., 1–100 kHz) using only one IC and two passive components, minimizing BOM count and PCB area. |
| Monostable Multivibrator | Microcontroller Reset Conditioning |
|
Use Scenario: Generating precise, fixed-duration pulses in response to external triggers - e.g., switch debounce, pulse stretching for actuator enable, or timing window generation. IC Role / Device Role / Timing Role: Triggered inverter with RC timing network - defines pulse width via external R/C values while ensuring clean output edge definition. Use Value: Delivers consistent pulse width (±5% tolerance) independent of input rise time, eliminating need for precision timing ICs in cost-sensitive designs. |
Use Scenario: Cleaning up slow-rising or noisy power-on reset (POR) or manual reset signals before feeding to MCU reset pin. IC Role / Device Role / Timing Role: Hysteresis-based reset synchronizer - suppresses supply ripple and contact bounce artifacts during power ramp-up or button press/release. Use Value: Guarantees minimum reset pulse width (>100 ns) and prevents spurious resets, improving system reliability in electrically harsh environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | TI part in SOT-23-5; VT+ = 2.9 V, VT− = 1.2 V at VCC = 4.5 V; slightly lower hysteresis (1.7 V); CPD = 6 pF | Lower dynamic power (due to smaller CPD), but reduced noise margin vs. XC7SH14GV,125's 1.8 V VH | Preferred where ultra-low dynamic power dominates over noise immunity - e.g., portable sensor nodes with tight energy budgets |
| 74AUP1G14GW,125 | Nexperia AUP variant in TSSOP5; identical pinout; lower ICC (≤30 μA), wider VCC (1.1–3.6 V), but narrower temp range (−40 °C to +85 °C) | Optimized for 1.8 V/2.5 V systems; not rated for +125 °C operation | Best for low-voltage, commercial-temp applications where extended temperature capability is unnecessary |

FAQ
Is XC7SH14GV,125 pin-compatible with other 5-pin Schmitt trigger inverters like SN74LVC1G14?
Yes - XC7SH14GV,125 uses SOT753 (SC-74A) package with identical pin 1 location and pinout (n.c./A/GND/Y/VCC) as SN74LVC1G14DBVR and 74AUP1G14GW,125. Mechanical compatibility enables drop-in replacement in existing layouts, though electrical differences (e.g., hysteresis magnitude, temperature rating) must be verified per application.
What is the maximum recommended capacitive load for stable operation?
The datasheet specifies dynamic characteristics up to CL = 50 pF, with tpd degradation limited to 13.5 ns max at VCC = 5.5 V. For reliable edge integrity and minimal overshoot, keep total load (including PCB trace and scope probe) ≤50 pF; above this, add series termination or reduce slew rate via input RC filtering.
Can XC7SH14GV,125 operate reliably at 1.8 V supply?
No - the absolute minimum VCC is 2.0 V per Table 6. At 1.8 V, the device may fail to meet VIH/VIL thresholds or exhibit undefined switching behavior. For 1.8 V systems, consider Nexperia's 74AUP1G14GW,125 (VCC = 1.1–3.6 V) instead.
Does pin 1 (n.c.) require any PCB routing or grounding?
Pin 1 is internally unconnected and must remain unbonded. It may be left floating, tied to GND, or connected to VCC - none affects functionality. Best practice is to leave it unconnected or ground it to minimize potential antenna effects in high-frequency layouts; do not route signal traces to it.
