Product details
Overview
74LVC3G14DP,125 from Nexperia is a triple 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 specified for -40 °C to +125 °C. It transforms slow-rising/falling signals into clean digital outputs and supports mixed-voltage interfacing in industrial sensor signal conditioning circuits.
For engineers reviewing the 74LVC3G14DP,125 datasheet, 74LVC3G14DP,125 pinout, 74LVC3G14DP,125 application, or 74LVC3G14DP,125 equivalent, key selection criteria include hysteresis voltage (0.70–1.90 V), propagation delay (0.5–4.7 ns), IOFF power-down protection, 5 V input tolerance, and TSSOP8 package compatibility with high-density PCB layouts.
Technical Context
This device implements three independent inverting Schmitt triggers with asymmetric threshold voltages (VT+ = 1.90–3.80 V, VT- = 1.00–2.50 V at VCC = 4.5–5.5 V) enabling robust noise rejection in noisy environments. Each channel features rail-to-rail output swing and supports unlimited input rise/fall times without oscillation.
The IOFF circuit actively disables outputs during partial power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and multi-rail system integrity. Input clamping diodes and ESD protection (HBM >2000 V, CDM >1000 V) ensure reliability in industrial I/O interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with both 3.3 V and 5 V logic families without level shifters. |
| Input Voltage Tolerance | 0 V to 5.5 V - allows safe connection to 5 V sources while powered from 1.65–3.3 V supplies. |
| Hysteresis Voltage (VH) | 0.70–1.90 V (VCC = 4.5–5.5 V) - provides noise margin against EMI-induced glitches on sensor or switch inputs. |
| Propagation Delay (tpd) | 0.5–4.7 ns - ensures sub-5 ns timing response for pulse shaping and oscillator applications up to ~100 MHz. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 LVC loads. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents destructive back-current flow during power sequencing or hot insertion. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial control enclosures. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.5 mm lead length, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 (1A, 2A, 3A) | Independent input terminals | Accept slow-rising/falling analog or digital signals; each triggers its own inverting Schmitt output. |
| 2, 5, 7 (3Y, 1Y, 2Y) | Independent output terminals | Provide clean, jitter-free inverted logic outputs with rail-to-rail swing and ±24 mA drive capability. |
| 4 | GND | Reference ground for all internal circuitry and output load return path. |
| 8 | VCC | Main supply input; powers all three channels and enables IOFF shutdown when pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent Schmitt triggers | Enables concurrent signal conditioning of three separate noisy inputs (e.g., encoder A/B/Z, limit switches, reset lines). |
| 5 V tolerant inputs on 1.65–3.3 V supply | Eliminates external level translators when interfacing legacy 5 V sensors or microcontrollers to modern low-voltage MCUs. |
| IOFF partial power-down protection | Prevents current backflow from live 5 V buses into unpowered subsystems - essential for modular power architecture compliance. |
| High noise immunity (hysteresis ≥0.7 V) | Rejects >700 mV of common-mode noise on long traces or unshielded cables in factory automation environments. |
| ESD robustness (HBM >2000 V, CDM >1000 V) | Withstands handling and board-level ESD events without latch-up or parametric shift - reduces field failure rate in assembly lines. |
Applications
| Wave and Pulse Shaper | Astable Multivibrator |
|---|---|
Use Scenario: Converting noisy analog waveforms from vibration sensors or proximity switches into clean square waves for MCU capture timers. IC Role / Device Role / Timing Role: Signal conditioner that eliminates chatter and metastability by applying hysteresis before edge detection. Use Value: Enables reliable zero-crossing detection in motor control feedback loops without software debouncing overhead. | Use Scenario: Generating clock signals for LED flashers or status indicators using only two inverters and an RC network. IC Role / Device Role / Timing Role: Core oscillator element where one inverter provides gain and another introduces phase shift via RC feedback. Use Value: Reduces BOM count by eliminating dedicated oscillator ICs - single chip delivers stable 1–10 kHz clocks with <5% frequency drift over temperature. |
| Monostable Multivibrator | Noise-Immune Switch Interface |
Use Scenario: Creating fixed-duration pulses from momentary push-button presses in human-machine interface panels. IC Role / Device Role / Timing Role: Pulse extender that converts short mechanical contact closures into precise 10–100 ms logic pulses. Use Value: Guarantees consistent pulse width regardless of button bounce duration - eliminates need for firmware debounce timers. | Use Scenario: Interfacing mechanical limit switches in CNC machines exposed to EMI from stepper drivers and spindle inverters. IC Role / Device Role / Timing Role: Input buffer that rejects transients <0.7 V while preserving true logic transitions. Use Value: Prevents false triggering of safety interlocks caused by radiated noise - meets IEC 61000-4-4 Level 3 immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G14DCUR | VSSOP8 package (2.3 mm width); identical electrical specs; lower thermal resistance than TSSOP8. | Better suited for space-constrained designs requiring higher power density; same pinout but smaller footprint. | Select when PCB real estate is limited and thermal performance at 24 mA load is critical. |
| 74LVC1G14GV,125 | Single-channel version in SOT886 (SC-70); same VCC range and hysteresis but only one inverter per package. | Requires three units for triple functionality; increases component count and layout complexity. | Choose only if design requires independent supply control per channel or incremental scalability. |
Compared with SN74LVC3G14DCUR, the 74LVC3G14DP,125 offers larger pad geometry for easier rework and better thermal dissipation in high-ambient environments; compared with 74LVC1G14GV,125, it reduces assembly cost and routing congestion by integrating three functions in one TSSOP8 footprint.

FAQ
What is the minimum supply voltage required for guaranteed 5 V input tolerance?
The 74LVC3G14DP,125 maintains full 5 V input tolerance down to VCC = 1.65 V, verified per Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values). Input clamping remains active and VIH/VIL thresholds stay within specification across the entire 1.65–5.5 V range - no minimum VCC threshold beyond 1.65 V is required for 5 V input operation.
Does the IOFF feature disable all three outputs simultaneously?
Yes. The IOFF circuit is global and activates when VCC is driven to 0 V, disabling all three outputs (pins 2, 5, 7) regardless of input states. This is confirmed in Section 1 (General description): "The IOFF circuitry disables the output" (singular noun used collectively for all outputs), and Table 3 lists GND and VCC as shared supply pins - no per-channel enable/disable control exists.
Can this device be used to build a relaxation oscillator with predictable frequency?
Yes. Figure 10 in the datasheet shows a validated two-inverter relaxation oscillator topology using the 74LVC3G14. Frequency depends on external R and C values and VCC, with K-factor curves provided in Figure 11. Typical accuracy is ±10% over -40 °C to +125 °C due to hysteresis voltage variation - suitable for non-critical timing like status blinking but not precision clocks.
Is the TSSOP8 package (SOT505-2) lead-free and RoHS compliant?
Yes. Nexperia confirms RoHS compliance and lead-free construction for all 74LVC3G14 variants including the 74LVC3G14DP,125 in SOT505-2. This is documented in Nexperia's official product change notices and material declarations, with solder profile compatibility matching JEDEC J-STD-020 Rev E for MSL 1 handling.
