Product details

Overview

74LVC2G14GW,125 from Nexperia is a dual inverting Schmitt trigger IC with 5 V tolerant inputs, operating from 1.65 V to 5.5 V supply, delivering ±24 mA output drive at 3.0 V, and featuring IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V logic domains in mixed-voltage systems such as industrial I/O interfaces and sensor signal conditioning circuits.

For engineers reviewing the 74LVC2G14GW,125 datasheet, 74LVC2G14GW,125 pinout, 74LVC2G14GW,125 application, or 74LVC2G14GW,125 equivalent, this device is selected for noise-immune waveform shaping, relaxation oscillator design, and robust input interfacing where hysteresis, overvoltage tolerance, and low-power CMOS operation are required.

Technical Context

The 74LVC2G14GW,125 implements two independent Schmitt-trigger inverters with asymmetric hysteresis (e.g., VH = 0.73 V typical at VCC = 3.0 V), enabling reliable noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

It supports wide-voltage operation (1.65–5.5 V), meets JEDEC standards JESD8-7 through JESD36, and delivers propagation delays as low as 2.7 ns (typical) at 4.5–5.5 V, with input thresholds VT+ and VT− varying predictably with supply voltage per Table 8.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - Enables direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters.
Input Voltage Tolerance	Up to 5.5 V - Allows safe connection to 5 V sources while powered from lower supplies (e.g., 3.3 V), critical for mixed-voltage board design.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to drive multiple standard CMOS/TTL loads or small capacitive traces without buffering.
Propagation Delay	2.7 ns (typ) at VCC = 4.5–5.5 V - Supports high-speed edge detection and timing-critical oscillator applications up to ~100 MHz fundamental frequency.
Hysteresis Voltage (VH)	0.73 V (typ) at VCC = 3.0 V - Provides robust noise margin (~24% of VCC) against EMI-induced glitches on sensor or switch inputs.
IOFF Leakage Current	±2 μA max at VCC = 0 V - Ensures negligible current flow during hot-swap or partial system power-down, protecting downstream circuitry.
Operating Temperature	–40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLCs, and extended-range embedded controllers.

Pinout & Package

TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1	1A - Input A of first inverter	Schmitt-trigger input accepting 0–5.5 V; enables clean inversion of noisy or slow-rising signals (e.g., mechanical switch bounce).
2	GND - Ground reference	0 V return path for both inverters; must be low-impedance to maintain noise immunity and stable threshold behavior.
3	2A - Input A of second inverter	Independent Schmitt input; allows dual-channel signal conditioning (e.g., differential pair shaping or redundant sensing paths).
4	2Y - Output Y of second inverter	Inverted, buffered output with rail-to-rail swing and ±24 mA drive capability; connects directly to next-stage logic or LED driver.
5	VCC - Supply voltage	Primary power rail (1.65–5.5 V); powers both inverters and IOFF circuitry; decoupling capacitor required near pin.
6	1Y - Output Y of first inverter	Complementary output to Pin 1; used in astable/monostable multivibrator feedback loops or wave-shaping networks.

Key Features

Feature	Design Value
5 V tolerant inputs	Accepts 0–5.5 V signals regardless of VCC (1.65–5.5 V), eliminating need for external clamping diodes in mixed-voltage interconnects.
IOFF partial power-down	Disables outputs when VCC = 0 V, blocking back-current flow - essential for live-insertion and hot-swap subsystems.
High noise immunity	Typical hysteresis of 0.73 V at 3.0 V supply ensures >200 mV noise rejection margin, suppressing false triggering from EMI or crosstalk.
Unlimited rise/fall times	No minimum input transition rate specified - supports ultra-slow signals (e.g., thermistor-based RC timing or manual switch inputs) without malfunction.
JEDEC-compliant voltage ranges	Fully compliant with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) - validated across industry-standard logic families.

Applications

Wave and Pulse Shaper

Astable Multivibrator

Use Scenario: Cleaning noisy analog sensor outputs (e.g., hall-effect or reed switch signals) before microcontroller GPIO sampling.

IC Role / Device Role / Timing Role: Dual Schmitt inverter acts as digital conditioner - first stage shapes rising/falling edges; second stage provides inverted copy for differential analysis.

Use Value: Eliminates contact bounce and EMI-induced jitter, reducing firmware debouncing overhead and improving real-time response accuracy.

Use Scenario: Generating precise square-wave clock signals for low-power timers or display refresh in portable instrumentation.

IC Role / Device Role / Timing Role: Cross-coupled configuration using both inverters and external RC network forms self-oscillating relaxation oscillator.

Use Value: Delivers stable, temperature-compensated frequency (e.g., 1–100 kHz) without crystals or dedicated timer ICs, saving BOM cost and PCB area.

Monostable Multivibrator

Level Translation Interface

Use Scenario: Converting short-duration pulses (e.g., from optical interrupters or safety limit switches) into standardized-width enable signals for motor drivers.

IC Role / Device Role / Timing Role: One inverter plus RC network creates edge-triggered one-shot; Schmitt input ensures clean triggering despite slow or noisy input edges.

Use Value: Guarantees consistent pulse width (e.g., 10–100 ms) independent of input rise time, simplifying downstream timing-critical actuation logic.

Use Scenario: Interfacing 5 V legacy sensors or actuators with modern 3.3 V microcontrollers in industrial control panels.

IC Role / Device Role / Timing Role: Acts as bidirectional voltage translator - accepts 5 V inputs while driving 3.3 V logic levels, leveraging its 5 V tolerant inputs and CMOS output swing.

Use Value: Removes need for discrete MOSFET translators or dedicated level-shifter ICs, reducing component count and layout complexity.

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	TI part in SOT-23-6 package; identical logic function but lacks IOFF circuitry and has narrower VCC range (1.65–5.5 V same, but no guaranteed operation below 1.65 V).	Not suitable for partial power-down scenarios; requires external isolation if VCC may be unpowered while inputs remain active.	Select only if IOFF is unnecessary and SOT-23 footprint is preferred over TSSOP6.
74AUP2G14GW,125	Nexperia AUP variant in same TSSOP6 package; lower static current (0.9 μA vs. 4 μA), wider hysteresis (1.0 V typ at 3.0 V), but reduced drive strength (±4 mA vs. ±24 mA).	Better for ultra-low-power always-on monitoring; unsuitable for driving capacitive loads or fan-out >2 without buffering.	Choose for battery-powered wake-up circuits where power budget dominates drive requirements.

Compared with SN74LVC2G14DBVR and 74AUP2G14GW,125, the 74LVC2G14GW,125 uniquely balances high drive strength, IOFF protection, and wide-voltage compatibility - making it optimal for industrial I/O modules requiring robustness across power states and mixed-voltage domains.

FAQ

What is the maximum input voltage the 74LVC2G14GW,125 can tolerate when VCC = 3.3 V?

The 74LVC2G14GW,125 supports input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values). This 5 V tolerance enables safe interfacing with higher-voltage peripherals while powered from 3.3 V, without external clamping components.

Does the 74LVC2G14GW,125 support true bidirectional level shifting?

No - the 74LVC2G14GW,125 is a unidirectional inverter with 5 V tolerant inputs and CMOS outputs referenced to VCC. It translates high-voltage inputs down to VCC-referenced logic levels but cannot translate low-voltage outputs up to 5 V. For true bidirectional translation, a dedicated bus switch or dual-supply level shifter is required.

Can the 74LVC2G14GW,125 be used to build a crystal-less oscillator?

Yes - its Schmitt-trigger inputs and predictable hysteresis allow stable relaxation oscillator construction using two inverters, resistors, and capacitors (as shown in Figure 10 of the datasheet). Frequency depends on RC values and supply voltage, with typical stability of ±5% over temperature and voltage - sufficient for non-critical timing like LED blinking or watchdog timeouts.

Is the TSSOP6 (SOT363-2) package RoHS-compliant and lead-free?

Yes - the 74LVC2G14GW,125 in SOT363-2 packaging is fully RoHS-compliant and lead-free, as documented in Nexperia's official product change notices and material declarations. The device meets EU Directive 2011/65/EU and subsequent amendments, with homogeneous lead content < 0.1 wt%.
