Product details
Overview
NLU1GT125MUTCG from onsemi is a single-channel, non-inverting 3-state buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for level translation and bus isolation in space-constrained digital systems. It operates from 1.65 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features input/output overvoltage tolerance up to 7.0 V.
For engineers reviewing the NLU1GT125MUTCG datasheet, pinout, applications, or equivalent options, key selection factors include its UDFN6 (1.2 × 1.0 mm) ultra-small footprint, guaranteed 3-state leakage ≤ ±2.5 µA, AEC-Q100 qualification (NLV variant), and compatibility with both LSTTL and CMOS logic families across industrial temperature range (−55 °C to +125 °C).
Technical Context
The NLU1GT125MUTCG implements a single high-speed CMOS buffer with active-high 3-state enable (OE), where OE = High places Y in high-impedance state. Its input structure accepts TTL-level thresholds (VIL = 0.8 V, VIH = 2.0 V) while driving rail-to-rail CMOS outputs (VOH > 0.8 VCC, VOL < 0.1 VCC).
Input and output pins tolerate voltages up to 7.0 V independent of VCC, enabling robust hot-swap and mixed-voltage interface operation. Propagation delays (tPLH/tPHL) are balanced and specified down to 1.65 V supply, with dynamic power modeled via CPD = 14 pF at 5.0 V.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all I/O and internal circuitry; must be connected to system ground plane |

| 3 | IN A | Non-inverting data input; accepts TTL-compatible thresholds and tolerates up to 7.0 V |
| 4 | NC | No-connect terminal; left unconnected per design - not internally bonded |
| 5 | OUT Y | Inverted-output buffer stage; delivers full CMOS swing and ±12.5 mA drive capability |
| 6 | VCC | Positive supply input; decoupling capacitor (0.1 µF) required within 2 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Inputs | VIL = 0.8 V / VIH = 2.0 V threshold ensures direct connection to legacy LSTTL outputs without external biasing |
| Overvoltage-Tolerant I/O | Input and output pins withstand −0.5 V to +7.0 V regardless of VCC - eliminates need for external clamping diodes |
| Ultra-Small UDFN6 Footprint | 1.2 × 1.0 mm body size reduces PCB area by >60% vs. standard SOT-363, critical for wearables and sensor nodes |
| Balanced Propagation Delays | tPLH and tPHL match within 0.3 ns @ 5.0 V - minimizes skew in timing-critical control paths |
| Power-Down Input Protection | Inputs remain protected and leakage-limited even when VCC = 0 V - enables safe partial-power-down system states |

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 |
|---|---|---|---|
| SN74LVC1G125DBVR | Same 1.65–5.5 V range and UDFN6 package, but lacks 7.0 V overvoltage tolerance; IOZ = ±10 µA (max) | Not qualified for automotive AEC-Q100; rated only to +85 °C ambient | Select when cost sensitivity outweighs overvoltage robustness and extended temperature requirements |
| 74LVC1G125GW,125 | Identical logic function and 7.0 V tolerant I/O, but uses larger SOT-353 (2.1 × 1.25 mm) package | Higher board area consumption; same industrial temp range but no AEC-Q100 documentation | Select when UDFN6 assembly capability is unavailable and 1.2× area penalty is acceptable |
Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the NLU1GT125MUTCG uniquely combines AEC-Q100 qualification, 7.0 V overvoltage tolerance, and the smallest UDFN6 footprint (1.2 × 1.0 mm), making it optimal for space- and reliability-critical automotive and industrial edge nodes.

FAQ
What is the maximum operating voltage for NLU1GT125MUTCG inputs and outputs?
The NLU1GT125MUTCG inputs and outputs are rated for −0.5 V to +7.0 V, independent of VCC supply voltage. This overvoltage tolerance allows safe interfacing with higher-voltage peripherals without external protection components. The specification is verified per JEDEC JESD78 latch-up testing and applies across the full −55 °C to +125 °C operating temperature range. This feature is explicitly confirmed in the Maximum Ratings table of the official NLU1GT125/D datasheet.
Does NLU1GT125MUTCG support 1.8 V logic systems?
Yes, NLU1GT125MUTCG fully supports 1.8 V logic systems: its recommended operating supply range starts at 1.65 V, and it guarantees TTL-compatible input thresholds (VIL = 0.53 V, VIH = 1.4 V min) and CMOS output swing (VOH > 1.44 V, VOL < 0.18 V) at VCC = 1.8 V. These values are specified in the DC Electrical Characteristics table for TA = 25 °C and across temperature extremes, confirming interoperability with 1.8 V microcontrollers and FPGAs.
What is the thermal performance of NLU1GT125MUTCG in its UDFN6 package?
The NLU1GT125MUTCG in UDFN6 (1.2 × 1.0 mm) has a junction-to-ambient thermal resistance (θJA) of 230 °C/W when mounted on a standard 2-layer FR4 board with minimum copper pad spacing. Its maximum junction temperature is rated at 150 °C, and it operates reliably from −55 °C to +125 °C ambient. These thermal parameters are validated per JEDEC JESD51-2 and documented in the Thermal Characteristics section of the NLU1GT125/D datasheet.
Is NLU1GT125MUTCG pin-compatible with other MiniGate buffers?
No, NLU1GT125MUTCG is not pin-compatible with other MiniGate buffers such as NLU1GT04 or NLU1GT32 due to differing pin assignments and functional configurations. Its UDFN6 pinout (GND, OE, IN A, NC, OUT Y, VCC) is unique to the 1-channel non-inverting 3-state buffer function. Pin compatibility is neither claimed nor verified in the NLU1GT125/D datasheet, and substitution requires PCB layout revision.
What does the "MUTCG" suffix indicate in NLU1GT125MUTCG?
The "MUTCG" suffix denotes a specific packaging and compliance configuration: "MU" = UDFN6 package, "T" = tape-and-reel packaging, "C" = Pb-free (RoHS-compliant), and "G" = halogen-free. This ordering code corresponds to the 1.2 × 1.0 mm, 0.4 mm pitch UDFN6 variant shipped in 3000-unit reels, as defined in the Ordering Information table on page 4 of the NLU1GT125/D datasheet.
