Product details

Overview

74HCT2G14GW,125 from Nexperia is a dual inverting Schmitt trigger IC with TTL-compatible inputs, housed in a TSSOP6 (SOT363-2) package. It operates from 4.5 V to 5.5 V, delivers ±4.0 mA output drive, features 0.4 V typical hysteresis at VCC = 4.5 V, and supports industrial temperature range (−40 °C to +125 °C). It is used for noise-immune signal conditioning in sensor interface and oscillator circuits.

For engineers reviewing the 74HCT2G14GW,125 datasheet, 74HCT2G14GW,125 pinout, 74HCT2G14GW,125 application, or 74HCT2G14GW,125 equivalent, this page provides verified functional identity, validated pin mapping, confirmed Schmitt-trigger transfer characteristics (VT+ = 1.20–1.90 V, VT− = 0.50–1.20 V), real-world timing behavior (tpd = 21–48 ns), and direct substitution guidance against industry-standard alternatives.

Technical Context

The 74HCT2G14GW,125 implements two independent CMOS inverters with Schmitt-trigger input stages, each featuring asymmetric hysteresis (VH = 0.40–0.71 V) optimized for TTL-level input thresholds. Its input clamp diodes enable safe interfacing to voltages exceeding VCC when current-limiting resistors are used.

It uses standard 74-series logic architecture with rail-to-rail output swing, balanced propagation delays between channels, and guaranteed operation across full industrial temperature range without derating below +89 °C - consistent with SOT363-2 thermal performance (3.7 mW/K derating above 83 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4.5 V to 5.5 V - ensures compatibility with 5 V TTL systems and stable operation under supply variation
Input Thresholds (VT+, VT−)	1.20–1.90 V / 0.50–1.20 V - enables reliable switching on slow-rising noisy signals in industrial environments
Hysteresis Voltage (VH)	0.40–0.71 V - suppresses chatter on marginal input transitions without external components
Propagation Delay (tpd)	21–48 ns @ CL = 50 pF - supports reliable timing in relaxation oscillators and pulse shaping up to ~10 MHz
Output Drive Capability	±4.0 mA - sufficient to directly drive LED indicators, small capacitive loads, or subsequent logic inputs
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive subsystems and industrial control enclosures
ESD Protection	HBM > 2000 V, CDM > 1000 V - withstands handling and board-level ESD events without latch-up

Pinout & Package

TSSOP6 (SOT363-2) plastic thin shrink small outline package; 6 leads; body width 1.25 mm; 0.65 mm pitch; exposed pad not present; RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	1A	First inverter input - accepts TTL-level signals (0.8 V/2.0 V thresholds); clamped to GND/VCC
2	GND	Ground reference - must be low-impedance connection to minimize noise coupling into Schmitt inputs
3	2A	Second inverter input - electrically isolated from 1A; identical threshold and hysteresis behavior
4	2Y	Second inverter output - inverted, rail-to-rail CMOS output; drives loads up to ±4.0 mA
5	VCC	Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable Schmitt operation
6	1Y	First inverter output - matches 2Y in timing, drive strength, and voltage levels; no internal cross-talk

Key Features

Feature	Design Value
TTL-compatible input levels	Guarantees interoperability with legacy 74LS/74F families without level-shifting circuitry
Unlimited input rise/fall times	Enables direct use with RC-generated waveforms (e.g., relaxation oscillators) without timing degradation
Clamp diode protection	Permits safe overvoltage input (up to VCC + 0.5 V) when series resistor limits current to ≤20 mA
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage
Low static current	ICC ≤ 20 μA max at VCC = 5.5 V and −40 °C to +125 °C - supports always-on sensing nodes

Applications

Waveform Shaping in Noisy Environments

Astable Multivibrator

Use Scenario: Converting slow, noisy analog sensor outputs (e.g., thermistor-based HVAC feedback) into clean digital pulses for microcontroller GPIO capture.

IC Role / Device Role / Timing Role: Dual Schmitt inverter acts as a noise-filtering front-end stage - first inverter cleans input, second inverts again to restore polarity while maintaining jitter-free edges.

Use Value: Eliminates false triggering caused by EMI-induced glitches on long PCB traces, reducing firmware debounce overhead by >90%.

Use Scenario: Generating fixed-frequency clock signals (e.g., 1–100 kHz) for LED flashers or status indicators using only two external resistors and one capacitor.

IC Role / Device Role / Timing Role: Each inverter forms half of a feedback loop with RC network; Schmitt hysteresis defines precise oscillation thresholds and duty cycle stability.

Use Value: Achieves frequency tolerance <±5% over temperature without trimming components - replaces discrete transistor-based oscillators.

Monostable Multivibrator

Power-On Reset Signal Generation

Use Scenario: Creating a precise, single-shot pulse (e.g., 10–100 ms) in response to a manual push-button press in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: One inverter serves as trigger amplifier, the other as delay element with RC timing network - Schmitt input rejects contact bounce.

Use Value: Guarantees exactly one clean edge per button press, eliminating need for software debouncing or additional RC filters.

Use Scenario: Generating a reliable, glitch-free reset pulse (>100 ms) after power supply stabilization in embedded controllers with unregulated 5 V rails.

IC Role / Device Role / Timing Role: Inverter pair converts slowly rising VCC into a sharp falling-edge reset signal synchronized to supply ramp rate.

Use Value: Ensures microcontroller enters known state before peripherals initialize - prevents boot failures due to marginal VCC ramp time.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schmitt-trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G14DBVR	Wider VCC range (1.65–5.5 V); CMOS input levels; lower ICC (≤10 μA); 3.3 V optimized	Better suited for mixed-voltage 3.3 V/5 V systems; less tolerant of TTL-level inputs	Select when interfacing with 3.3 V MCUs and requiring ultra-low quiescent current
MC74VHC2G14DTT1G	Wider VCC (2.0–5.5 V); higher speed (tpd = 11–18 ns @ 5 V); same pinout; higher cost	Preferred for high-speed waveform reconstruction where sub-20 ns delay is critical	Select when minimum propagation delay and broad supply flexibility outweigh cost sensitivity

Compared with SN74LVC2G14DBVR and MC74VHC2G14DTT1G, the 74HCT2G14GW,125 uniquely balances TTL compatibility, industrial temperature support, and cost-effective TSSOP6 packaging - making it optimal for legacy 5 V designs requiring robust noise immunity without redesigning level-shifting networks.

FAQ

Can the 74HCT2G14GW,125 operate reliably at 3.3 V?

No - the 74HCT2G14GW,125 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, its TTL input thresholds (VIH = 2.0 V min) become marginal, and output drive degrades significantly. For 3.3 V systems, use the pin-compatible 74LVC2G14 instead, which guarantees VIH = 2.0 V at VCC = 3.3 V.

What is the maximum capacitive load the 74HCT2G14GW,125 can drive without timing degradation?

The device is characterized up to 50 pF (per output), with tpd increasing linearly beyond that. Driving >100 pF causes measurable delay increase (>2× nominal) and potential edge rounding. For heavier loads, add a buffer stage or use the higher-drive 74AHCT2G14 variant rated for 8 mA.

Does the 74HCT2G14GW,125 require external pull-up or pull-down resistors on unused inputs?

No - all inputs have internal clamp diodes and defined logic thresholds. However, floating inputs must be avoided: tie unused inputs directly to VCC or GND. Leaving them open risks increased ICC, erratic output behavior, and ESD susceptibility due to undefined node voltage.

How does the hysteresis voltage change with temperature and supply voltage?

VH remains stable across temperature: 0.40–0.71 V over −40 °C to +125 °C at VCC = 4.5–5.5 V. It increases slightly with VCC - e.g., VH ≈ 0.40 V at 4.5 V, rising to ≈0.71 V at 5.5 V - ensuring consistent noise margin regardless of supply drift within spec.
