Product details
Overview
NLVU1GT125AMUTCG from onsemi is an automotive-grade, single-channel non-inverting 3-state buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, operating from 1.65 V to 5.5 V supply, featuring 3.8 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, and AEC-Q100 qualification for under-hood control modules.
For engineers reviewing the NLVU1GT125AMUTCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 (1.45 × 1.0 mm) ultra-small footprint, OE-controlled 3-state operation, input overvoltage tolerance up to 7.0 V, and guaranteed performance across −55 °C to +125 °C.
Technical Context
This device implements a single high-speed CMOS buffer with active-high 3-state enable (OE), where logic HIGH on OE enables the non-inverting path from IN A to OUT Y, and logic LOW places OUT Y in high-impedance state. Input thresholds meet LSTTL levels (VIL = 0.8 V, VIH = 2.0 V), while output swing exceeds VOH > 0.8 VCC and VOL < 0.1 VCC under load.
Input and output structures are rated for ±20 mA diode current and withstand DC voltages from −0.5 V to +7.0 V independent of VCC, enabling robust interfacing in mixed-voltage domains. Propagation delays (tPLH/tPHL), enable/disable times (tPZL/tPLZ), and leakage currents (IOZ < ±2.5 µA) are fully characterized across automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports dual-rail interface between 1.8 V, 3.3 V, and 5.0 V logic domains |
| Propagation Delay (tPD) | 3.8 ns (typ) @ VCC = 5.0 V, CL = 15 pF - enables timing-critical signal buffering in automotive serial buses |
| Output Drive | ±12.5 mA - sufficient to drive multiple LSTTL loads or moderate capacitive loads without external buffers |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - ensures reliable recognition of legacy TTL-level signals across temperature |
| Overvoltage Tolerance | Inputs/outputs withstand −0.5 V to +7.0 V - eliminates need for external clamping diodes in noisy environments |
| Operating Temperature | −55 °C to +125 °C - validated for engine control units, body controllers, and ADAS sensor interfaces |
| Quiescent Current | ICC ≤ 1.0 µA (max) @ TA = 25 °C - minimizes standby power in always-on vehicle subsystems |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), case 517AQ, exposed Cu pad for thermal enhancement, Pb-free, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for all internal circuitry and output current sink |
| 2 - OE | 3-State enable input | Active-HIGH control: logic HIGH enables buffer; logic LOW forces high-impedance output |
| 3 - IN A | Non-inverting data input | Accepts TTL-level signals; internally protected to ±20 mA and 7.0 V |
| 4 - NC | No connect | Internally unconnected terminal; must be left floating or tied to GND per layout guidelines |
| 5 - OUT Y | Buffered non-inverting output | CMOS-level output capable of sourcing/sinking ±12.5 mA with rail-to-rail swing |
| 6 - VCC | Positive supply | Power supply input; decoupling capacitor required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified (Grade 1) | Validated for automotive applications requiring −40 °C to +125 °C ambient operation and PPAP compliance |
| TTL-compatible input thresholds | Ensures interoperability with legacy microcontrollers, FPGAs, and discrete logic without level-shifting |
| 7.0 V overvoltage tolerant I/O | Eliminates external protection components when interfacing with higher-voltage sensors or actuators |
| Ultra-small UDFN6 package | Reduces PCB area by >50% vs. SOIC-6; enables dense routing in space-constrained ECUs and ADAS modules |
| Low dynamic power (CPD = 14 pF) | Minimizes switching power at high frequencies: PD ≈ 14 pF × VCC² × fin + ICC × VCC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G125DTT1G | Same UDFN6 package, but rated only to +85 °C; no AEC-Q100 qualification; slightly higher ICC (max 1 µA vs. 1 µA) | Suitable for industrial or consumer applications; not approved for automotive under-hood use | Select when automotive qualification is unnecessary and cost sensitivity outweighs temperature margin |
| SN74LVC1G125DBVR | Higher max output drive (±32 mA); wider VCC range (1.65–5.5 V); same pinout; no AEC-Q100 certification | Better suited for driving heavier capacitive loads or longer traces; lacks automotive traceability and PPAP support | Choose for non-automotive designs needing stronger drive capability and broader voltage flexibility |
Compared with MC74VHC1G125DTT1G and SN74LVC1G125DBVR, the NLVU1GT125AMUTCG uniquely delivers AEC-Q100 Grade 1 qualification, 7.0 V I/O tolerance, and guaranteed −55 °C to +125 °C operation-making it the only option qualified for safety-critical automotive signal routing where reliability and environmental resilience are mandatory.

FAQ
What is the operating temperature range for NLVU1GT125AMUTCG?
The NLVU1GT125AMUTCG is specified for operation from −55 °C to +125 °C ambient temperature and is AEC-Q100 qualified for automotive Grade 1 applications. This range covers under-hood environments such as engine control units and transmission control modules where thermal stress is extreme. The NLVU1GT125AMUTCG maintains full electrical performance-including propagation delay, output drive, and leakage-across this entire range, as verified in the official onsemi datasheet revision 7.
Does NLVU1GT125AMUTCG support 1.8 V logic interfacing?
Yes, NLVU1GT125AMUTCG operates down to 1.65 V VCC and accepts TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), making it compatible with 1.8 V microcontrollers when VCC = 1.8 V. Its inputs tolerate up to 7.0 V regardless of supply voltage, allowing safe interfacing with higher-voltage peripherals. The NLVU1GT125AMUTCG output swing scales with VCC, delivering VOH > 0.8 × VCC and VOL < 0.1 × VCC under load.
What is the function of Pin 4 (NC) on NLVU1GT125AMUTCG?
Pin 4 on NLVU1GT125AMUTCG is designated NC (No Connect) and is internally unconnected. It must not be soldered to any net on the PCB; best practice is to leave it floating or tie it to GND only if required by board-level EMI mitigation strategies-per onsemi's layout guidance in the 517AQ package drawing. The NLVU1GT125AMUTCG functionality is fully defined by Pins 1 (GND), 2 (OE), 3 (IN A), 5 (OUT Y), and 6 (VCC); Pin 4 has no electrical role in the NLVU1GT125AMUTCG operation.
Is NLVU1GT125AMUTCG pin-compatible with NLU1GT125MUTCG?
No, NLVU1GT125AMUTCG is not pin-compatible with NLU1GT125MUTCG. While both share the UDFN6 footprint, NLVU1GT125AMUTCG uses case 517AQ (1.45 × 1.0 mm, 0.5 mm pitch), whereas NLU1GT125MUTCG uses case 517AA (1.2 × 1.0 mm, 0.4 mm pitch). Their pad layouts differ in dimensions and pitch, requiring separate land patterns. The NLVU1GT125AMUTCG also adds automotive-specific process controls and AEC-Q100 validation not present in the commercial NLU1GT125MUTCG variant.
What is the maximum output capacitive load supported by NLVU1GT125AMUTCG?
The NLVU1GT125AMUTCG is characterized for CL = 15 pF and CL = 50 pF in AC specifications, with propagation delay increasing from 3.8 ns to 5.3 ns at 5.0 V VCC. Its 3-state output capacitance (COUT) is 6 pF, and input capacitance (CIN) is 10 pF. While not explicitly rated for higher loads, stable operation up to ~75 pF is achievable with proper termination and layout; for loads exceeding 50 pF, the NLVU1GT125AMUTCG may require series damping or reduced edge rates to maintain signal integrity.
