Product details

Overview

XC7SH14GW,125 from Nexperia is a single-channel CMOS inverting Schmitt trigger in TSSOP5 (SOT353-1) package, operating from -40 °C to +125 °C. It converts slow-rising/falling input signals into clean, jitter-free digital outputs with 0.5 V hysteresis at VCC = 5.5 V, 1.35 V VT+ and 0.9 V VT− at VCC = 3.0 V, and 8.6 ns typical propagation delay (CL = 15 pF, VCC = 5.0 V). It is used in waveform shaping circuits for microcontroller reset conditioning and sensor signal debouncing.

For engineers reviewing the XC7SH14GW,125 datasheet, XC7SH14GW,125 pinout, XC7SH14GW,125 application, or XC7SH14GW,125 equivalent, key selection criteria include hysteresis voltage stability over temperature, supply voltage range (2.0–5.5 V), ESD robustness (HBM >2000 V), and low ICC (≤40 μA at VCC = 5.5 V), especially for battery-powered edge-node signal conditioning.

Technical Context

The XC7SH14GW,125 implements a single inverting Schmitt-trigger buffer using high-speed Si-gate CMOS technology. Its transfer characteristic features asymmetric positive-going (VT+) and negative-going (VT−) thresholds, delivering 0.45–1.6 V hysteresis depending on VCC and temperature, enabling reliable noise rejection on noisy analog or mechanical switch inputs.

It operates across two industrial temperature ranges (−40 °C to +85 °C and −40 °C to +125 °C) with specified static and dynamic performance including VOL ≤ 0.55 V (IO = 8.0 mA, VCC = 4.5 V), VOH ≥ 3.70 V (IO = −8.0 mA, VCC = 4.5 V), and CPD = 12 pF for dynamic power estimation.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - Supports dual-supply systems and direct interfacing with 3.3 V and 5 V logic families.
VT+ / VT−	3.15 V / 1.35 V at VCC = 4.5 V - Defines switching thresholds for noise margin optimization in relaxation oscillators and switch debouncing.
Hysteresis (VH)	1.8 V at VCC = 4.5 V - Ensures ≥1.3× typical noise amplitude rejection before false triggering occurs.
tpd (CL = 15 pF)	3.2–11.0 ns - Enables use in sub-100 MHz clock conditioning and fast edge regeneration without timing skew.
ESD Rating	HBM >2000 V, CDM >1000 V - Allows direct PCB handling and integration in unshielded industrial I/O modules.
ICC (max)	40 μA at VCC = 5.5 V - Enables multi-year operation from coin-cell batteries in low-duty-cycle sensor wake-up circuits.

Pinout & Package

TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	n.c.	No internal connection - must be left floating or grounded per layout best practice; no routing required.
2	A	Inverting Schmitt trigger input - accepts slow analog transitions (e.g., from thermistor dividers or mechanical switches).
3	GND	Ground reference - requires low-impedance local decoupling (e.g., 100 nF ceramic) adjacent to pin 3.
4	Y	Inverted, hysteresis-shaped output - drives standard CMOS loads up to 8 mA sink/source with rail-to-rail swing.
5	VCC	Positive supply - must be filtered independently from digital VCC domains to avoid threshold instability.

Key Features

Feature	Design Value
Schmitt-trigger hysteresis	0.45–1.6 V adjustable via VCC - eliminates chatter on slow-switching sensors without external RC networks.
Propagation delay symmetry	tPLH ≈ tPHL - ensures balanced rise/fall timing critical for oscillator duty cycle control (e.g., Fig. 13 relaxation oscillator).
CMOS input levels	VIH/VIL compatible with 3.3 V and 5 V logic - enables direct interface with MCU GPIOs, ADC references, and DAC outputs.
Low ICC at VCC = 5.5 V	≤40 μA - reduces quiescent current in always-on monitoring nodes where power budget is <100 μW.
High noise immunity	≥1.3× typical EMI amplitude rejection - validated by 2.2 V VT+–VT− window at VCC = 5.5 V across full temperature range.

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	Wider VCC range (1.65–5.5 V); lower VT+ (≈1.8 V at 3.3 V); 5.5 ns tpd (CL = 15 pF)	Better suited for 1.8 V logic domains; slightly reduced hysteresis margin at low VCC	Select when interfacing with 1.8 V FPGAs or ultra-low-voltage MCUs; verify VT+/VT− fit system noise floor.
74AUP1G14GW,125	Nexperia AUP family; lower ICC (≤30 μA); higher VT+ (3.4 V at 5.0 V); same TSSOP5 package	Optimized for sub-10 μA standby power; tighter hysteresis control at high VCC	Prefer for battery life-critical designs requiring <30 μA quiescent current and stable 5 V operation.

Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the XC7SH14GW,125 offers superior hysteresis consistency across −40 °C to +125 °C and higher ESD tolerance, making it optimal for harsh-environment industrial signal conditioning where thermal drift and EMI resilience are primary concerns.

FAQ

What is the maximum recommended supply voltage for XC7SH14GW,125?

The absolute maximum supply voltage is +7.0 V per Table 5, but the recommended operating range is 2.0 V to 5.5 V (Table 6). Operation above 5.5 V risks exceeding limiting values and may cause irreversible damage or parametric shift, especially at elevated temperatures.

Can pin 1 (n.c.) be tied to GND or VCC?

No - pin 1 is internally not connected and must remain unconnected (floating) or optionally grounded for mechanical stability; connecting it to VCC or GND violates the pin description in Table 3 and may induce leakage paths or package stress-induced parameter shifts.

How does hysteresis change with supply voltage?

Hysteresis voltage (VH = VT+ − VT−) increases linearly with VCC: 0.45 V at 3.0 V, 1.8 V at 4.5 V, and 2.2 V at 5.5 V (Table 8). This scaling ensures consistent noise margin percentage (≈40%) across the full operating range.

Is XC7SH14GW,125 qualified for automotive applications?

No - the datasheet explicitly states "Non-automotive qualified products" in Section 18 and provides no AEC-Q200 stress test data. It is rated for industrial temperature range (−40 °C to +125 °C) but lacks automotive qualification, fault coverage, or PPAP documentation.
