Product details

Overview

74LVC1G14GV,125 from Nexperia is a single Schmitt-trigger inverter IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, delivers ±24 mA output drive at 3.0 V, and supports partial power-down via IOFF circuitry. It is used in wave shaping, relaxation oscillators, and level translation between 3.3 V and 5 V logic domains.

For engineers reviewing the 74LVC1G14GV,125 datasheet, 74LVC1G14GV,125 pinout, 74LVC1G14GV,125 application, or 74LVC1G14GV,125 equivalent, this page provides verified functional identity, SC-74A (SOT753) package mapping, confirmed Schmitt-trigger transfer characteristics (VT+ = 1.29 V / VT− = 0.88 V at VCC = 3.0 V), IOFF-enabled power-down behavior, and real-world use cases in pulse shaping and multivibrator circuits.

Technical Context

The device implements a CMOS-based Schmitt-trigger inverter with hysteresis (VH = 0.5 V typical at VCC = 3.0 V), enabling robust noise immunity and clean edge regeneration on slow or noisy input signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It complies with JEDEC standards 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), and supports operation across −40 °C to +125 °C with latch-up immunity exceeding 250 mA.

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 Thresholds (VCC = 3.0 V)	VT+ = 1.29 V, VT− = 0.88 V - Provides 410 mV hysteresis for reliable noise rejection on analog-like or slow-rising digital inputs.
Output Drive Strength	±24 mA at VCC = 3.0 V - Sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads (<50 pF) without buffering.
Propagation Delay	0.7 ns (min) to 7.0 ns (max) at VCC = 3.0 V - Supports high-speed signal conditioning in timing-critical paths up to ~140 MHz.
IOFF Leakage Current	±2 μA max at VCC = 0 V - Ensures safe bus sharing and prevents backfeed in hot-swap or partial-power-down systems.
ESD Robustness	HBM >2000 V, CDM >1000 V - Meets industrial-grade ESD requirements without external protection components.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive, industrial control, and extended-environment applications.

Pinout & Package

74LVC1G14GV,125 is housed in the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, with gull-wing leads and pin 1 index located below the marking "V14".

Pin/Terminal	Circuit Role	Design Meaning
1 (n.c.)	No-connect terminal	Internally unconnected; must remain floating - no routing or grounding required.
2 (A)	Data input	Schmitt-trigger input accepting 0–5.5 V; tolerant of slow edges and noise up to ±200 mV.
3 (GND)	Ground reference	Primary 0 V return path; must be low-impedance and adjacent to VCC for stable switching.
4 (Y)	Data output	Inverted, rail-to-rail CMOS output with IOFF disable when VCC = 0 V.
5 (VCC)	Supply voltage	Power rail (1.65–5.5 V); requires local 100 nF ceramic decoupling within 3 mm.

Key Features

Feature	Design Value
Wide supply range	1.65–5.5 V operation enables drop-in replacement across legacy and modern logic families.
Overvoltage-tolerant inputs	Accepts 5.5 V inputs regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interfaces.
IOFF partial power-down	Outputs go high-impedance when VCC = 0 V - prevents back-current in powered-backplane or hot-plug systems.
High noise immunity	410 mV typical hysteresis at 3.0 V suppresses glitches from EMI, crosstalk, or long PCB traces.
Unlimited rise/fall times	Guaranteed switching even with RC-filtered or slew-limited inputs - ideal for debouncing and oscillator feedback paths.

Applications

Wave Shaping

Astable Multivibrator

Use Scenario: Converting noisy or slow-rising sensor outputs (e.g., thermistor divider, mechanical switch bounce) into clean digital pulses.

IC Role / Device Role / Timing Role: Schmitt-trigger inverter acting as input conditioner and edge regenerator.

Use Value: Eliminates false triggering by rejecting sub-threshold noise; ensures monotonic transitions with defined VT+/VT− thresholds.

Use Scenario: Generating continuous square-wave clock signals using external RC network (e.g., Fig. 10 in datasheet).

IC Role / Device Role / Timing Role: Core inverter element in relaxation oscillator topology with feedback resistor and timing capacitor.

Use Value: Delivers stable, temperature-compensated frequency (K-factor = 1.0 at VCC = 3.0 V) without external crystals or dedicated timer ICs.

Monostable Multivibrator

Mixed-Voltage Level Translation

Use Scenario: Creating precise one-shot pulses from push-button or interrupt signals in microcontroller systems.

IC Role / Device Role / Timing Role: Inverter-based pulse stretcher with RC timing network defining pulse width.

Use Value: Generates consistent, jitter-free monopulses independent of input edge rate - critical for reliable interrupt synchronization.

Use Scenario: Interfacing 5 V legacy peripherals (e.g., UART transceivers, sensors) with 3.3 V or 1.8 V MCU I/O banks.

IC Role / Device Role / Timing Role: Bidirectional level translator leveraging overvoltage-tolerant inputs and rail-swing outputs.

Use Value: Enables direct connection without external MOSFETs or resistive dividers - reduces BOM count and layout area.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G14DBVR	TI part in SOT-23-5 (same pinout), identical VCC range and IOFF, but lower max output drive (±24 mA same), slightly higher typical propagation delay (3.5 ns vs 3.0 ns at 3.3 V).	Same functional role; validated for wave shaping and oscillator use, but not qualified to +125 °C - limited to industrial (−40 °C to +85 °C) grade.	Select when TI sourcing preference exists and extended temperature is not required.
74AUP1G14GW,125	Nexperia AUP variant in TSSOP5; lower static current (0.9 μA vs 4 μA), wider VCC range (0.8–3.6 V), no IOFF, no 5 V tolerance - incompatible with mixed 5 V/3.3 V systems.	Optimized for ultra-low-power battery applications only; cannot replace 74LVC1G14GV,125 where 5 V input tolerance or IOFF is needed.	Select only for sub-3.6 V, low-I_CC designs where 5 V compatibility and power-down safety are irrelevant.

Compared with SN74LVC1G14DBVR and 74AUP1G14GW,125, the 74LVC1G14GV,125 uniquely combines 5.5 V input tolerance, IOFF-enabled safe power-down, and full −40 °C to +125 °C qualification - making it the sole choice for automotive, industrial, and mixed-voltage hot-swap applications requiring guaranteed robustness.

FAQ

What is the function of the n.c. pin on 74LVC1G14GV,125?

Pin 1 is a no-connect terminal with no internal bond wire or silicon connection. It must remain unconnected - neither grounded nor routed - and serves only as a mechanical alignment marker. Its presence does not affect electrical performance or thermal behavior.

Can 74LVC1G14GV,125 drive a 50 pF load at 10 MHz?

Yes. At VCC = 3.3 V, its typical propagation delay is 3.0 ns and CPD is 15.4 pF. With 50 pF load and 10 MHz toggle rate, dynamic power dissipation remains under 50 μW, well within its 250 mW thermal limit in SC-74A package. Output rise/fall times stay <5 ns.

Does 74LVC1G14GV,125 support true bidirectional level translation?

No. It is a unidirectional inverter: input A drives output Y. While its overvoltage-tolerant inputs accept 5 V signals at any VCC ≥1.65 V, and its output swings rail-to-rail, it lacks automatic direction sensing or dual-supply capability required for true bidirectional translation.

How does IOFF behave during partial power-down?

When VCC drops to 0 V, the IOFF circuit forces the output Y into high-impedance state, limiting leakage to ±2 μA maximum. This prevents back-current flow from powered downstream circuits into the unpowered device - critical for system-level power sequencing and hot-swap safety.
