Product details
Overview
NLU1G14AMX1TCG from onsemi is a single high-speed CMOS Schmitt-trigger inverter in a 1.45 mm × 1.0 mm UDFN6 package, featuring 4.0 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, and overvoltage-tolerant (OVT) I/O pins rated to 7.0 V independent of supply voltage - used for noise-immune signal conditioning in automotive body control modules.
For engineers reviewing the NLU1G14AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include hysteresis voltage (0.30–1.60 V), operating temperature range (−55 °C to +125 °C), input transition rate independence, and Pb-free UDFN6 footprint compatibility with space-constrained PCB layouts.
Technical Context
The NLU1G14AMX1TCG implements a dual-threshold Schmitt-trigger input stage with VT+ = 1.85–3.85 V and VT− = 0.9–3.05 V (depending on VCC), enabling robust noise rejection on slow-rising signals. Its rail-to-rail OVT I/O supports mixed-voltage interfacing without level shifters.
It operates across 1.65 V to 5.5 V supply, with guaranteed performance up to +125 °C and storage down to −65 °C. Propagation delays are specified for CL = 15 pF and 50 pF loads, and input transition rate has no limit under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 4.0 ns @ VCC = 5.0 V, CL = 15 pF - supports >100 MHz square-wave shaping in timing-critical paths |
| VT+ / VT− | 1.85–3.85 V / 0.9–3.05 V - provides ≥0.30 V hysteresis for reliable noise margin against EMI in automotive environments |
| IO Max | ±12.5 mA - drives standard TTL/CMOS loads without external buffers |
| OVT Rating | Input/output tolerant to −0.5 V to +7.0 V - eliminates need for external clamping diodes when interfacing with higher-voltage sensors |
| Package | UDFN6, 1.45 mm × 1.0 mm, 0.5 mm pitch - fits 1.5 mm² board area, compatible with reflow soldering per J-STD-020 MSL Level 1 |
Pinout & Package
Package: UDFN6 (Case 517AQ), 1.45 mm × 1.0 mm, 0.5 mm pitch, exposed thermal pad (non-electrical), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path |
| 2 | NC | No-connect terminal - must be left floating or grounded per layout best practice; not internally bonded |
| 3 | IN A | Schmitt-trigger input - accepts slow or noisy digital signals and outputs clean square waves |
| 4 | NC | No-connect terminal - electrically isolated; no internal connection |
| 5 | OUT Y | Inverted Schmitt output - provides rail-to-rail swing with hysteresis-based noise immunity |
| 6 | VCC | Positive supply - powers internal logic and output driver; supports decoupling capacitor placement adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant I/O | Withstands −0.5 V to +7.0 V on IN A and OUT Y regardless of VCC - simplifies mixed-voltage system integration |
| Wide supply range | Operates from 1.65 V to 5.5 V - supports battery-powered and multi-rail industrial systems without voltage translation |
| Hysteresis control | VT+ − VT− = 0.30–1.60 V - ensures stable switching in presence of >200 mV peak-to-peak noise |
| Power-down protection | Inputs remain high-impedance and non-latching during VCC = 0 V - prevents backfeeding and bus contention |

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 | Same 1.65–5.5 V VCC range, but only 3.0 ns tPD (typ) at 3.3 V; no OVT - max VIN = VCC + 0.5 V | Requires external clamping for >5.5 V transients; unsuitable for direct 7 V sensor interfacing | Select when speed is prioritized over overvoltage tolerance and board space allows discrete protection |
| MC74VHC1G14DTT1G | Wider temp range (−55 °C to +125 °C same), but only 2.5 ns tPD (typ) at 5 V; OVT not specified - max VIN = VCC + 0.3 V | Lacks documented OVT capability; requires design validation for 7 V transient immunity | Choose for legacy VHC-family compatibility where absolute min/max timing is critical and voltage margins are tightly controlled |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DTT1G, the NLU1G14AMX1TCG uniquely guarantees ±7.0 V overvoltage tolerance on both input and output pins independent of supply, making it the only option among the three qualified for direct interfacing with unregulated 5–7 V automotive sensor rails without external protection components.

FAQ
What is the maximum input voltage rating for the NLU1G14AMX1TCG?
The NLU1G14AMX1TCG features overvoltage-tolerant (OVT) inputs rated from −0.5 V to +7.0 V, regardless of VCC level. This specification is verified per datasheet Maximum Ratings table and enables direct interfacing with 7 V sensors or legacy automotive signals without external clamping diodes. The NLU1G14AMX1TCG maintains this rating across its full operating temperature range of −55 °C to +125 °C.
Does the NLU1G14AMX1TCG support operation at 1.8 V supply?
Yes, the NLU1G14AMX1TCG is fully specified for operation at VCC = 1.8 V within its recommended range of 1.65 V to 5.5 V. At 1.8 V, DC electrical characteristics including VT+, VT−, VOH, and VOL are guaranteed per the datasheet's DC Electrical Characteristics table, and AC performance (e.g., tPLH/tPHL) remains functional though not characterized below 3.0 V in the AC table. The NLU1G14AMX1TCG delivers reliable Schmitt-trigger behavior even at minimum supply.
How many no-connect (NC) pins does the NLU1G14AMX1TCG have, and how should they be handled?
The NLU1G14AMX1TCG UDFN6 package has two no-connect pins: Pin 2 and Pin 4. These terminals are not internally bonded and must be left floating or tied to GND per PCB layout best practices to minimize parasitic coupling. Neither pin may be used for thermal relief or signal routing. This configuration is confirmed in Figure 1 (Pinout) and PIN ASSIGNMENT table of the official NLU1G14/D datasheet. The NLU1G14AMX1TCG's functionality is unaffected by NC pin treatment, but grounding improves EMI resilience.
What is the hysteresis voltage (VH) of the NLU1G14AMX1TCG at 3.3 V supply?
At VCC = 3.3 V, the NLU1G14AMX1TCG exhibits a typical hysteresis voltage (VH) of 0.40 V, with a guaranteed minimum of 0.30 V and maximum of 0.50 V over temperature (−55 °C to +125 °C). This value is derived directly from the DC Electrical Characteristics table, where VH = VT+ − VT−. The NLU1G14AMX1TCG's hysteresis ensures stable switching in presence of noise up to ±150 mV around either threshold, making it suitable for noisy automotive and industrial environments.
Is the NLU1G14AMX1TCG pin-compatible with other variants in the NLU1G14 family?
Yes, all NLU1G14 variants - including NLU1G14MUTCG (1.2 × 1.0 mm), NLU1G14AMUTCG (1.45 × 1.0 mm), and NLU1G14CMUTCG (1.0 × 1.0 mm) - share identical pinout (GND, NC, IN A, NC, OUT Y, VCC) and electrical specifications. The NLU1G14AMX1TCG uses Case 517AQ (1.45 × 1.0 mm), differing only in package dimensions and thermal pad geometry - no PCB redesign is required when migrating between variants, provided land pattern accommodates the largest outline.
