Product details
Overview
NLU1GT126MUTCG from onsemi is a single-channel, non-inverting 3-state buffer IC with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for signal routing 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 - enabling robust interfacing between mixed-voltage logic domains in industrial control modules.
For engineers reviewing the NLU1GT126MUTCG datasheet, pinout, applications, or equivalent options, key selection considerations include its UDFN6 (1.2 × 1.0 mm) ultra-small footprint, OE-controlled 3-state operation, LSTTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), and guaranteed 125 °C operating temperature capability.
Technical Context
The NLU1GT126MUTCG implements a single high-speed CMOS buffer stage with active-low 3-state enable (OE), where logic high on OE disables the output into high-impedance mode. Its input structure includes clamping diodes and ESD protection rated to ±500 mA latch-up immunity per JESD78.
Output drive is rail-to-rail (VOH > 0.8 VCC, VOL < 0.1 VCC under load), and both input and output pins tolerate 7.0 V regardless of VCC - supporting hot-swap and level-shifting use cases without external components. Propagation delays (tPLH/tPHL) and enable/disable times (tPZL/tPLZ) are characterized across 1.65–5.5 V supply and −55 °C to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 3.3 V, and 5 V logic families without level shifters. |
| tPD (Typ) | 3.8 ns @ VCC = 5.0 V, CL = 15 pF - supports >100 MHz data rates in point-to-point signal paths. |
| IO Max | ±12.5 mA - sufficient to drive standard 50 pF loads or multiple 74LVC inputs without fanout limitation. |
| VIN Tolerance | −0.5 V to +7.0 V - allows safe connection to higher-voltage buses or unpowered subsystems during power sequencing. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| Package | UDFN6, 1.2 × 1.0 mm, 0.4 mm pitch - reduces PCB area by >60% vs. SOT-363 while maintaining thermal performance. |
| MSL Level | Level 1 (unlimited floor life) - simplifies manufacturing handling and eliminates bake requirements prior to reflow. |
Pinout & Package
Package: UDFN6 (1.2 mm × 1.0 mm × 0.5 mm), case 517AA, Pb-free, bottom-exposed thermal pad (no internal connection). Pin 1 marked by chamfered corner; pin numbering follows standard UDFN counter-clockwise sequence.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all I/O and internal circuitry; must be connected to low-impedance system ground plane. |
| 2 | OE | Active-low 3-state enable input; logic low enables output buffer, logic high places Y in high-impedance state. |
| 3 | IN A | Non-inverting data input; accepts TTL-level thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) across full VCC range. |
| 4 | NC | No internal connection; left floating or tied to GND per layout best practice to reduce parasitic coupling. |
| 5 | OUT Y | Inverted logic not applied - output replicates IN A when enabled; full CMOS swing (0 V to VCC) with 12.5 mA sink/source. |
| 6 | VCC | Positive supply input; bypass capacitor (100 nF ceramic) required within 2 mm of this pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| LSTTL-Compatible Inputs | Guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 5.0 V - ensures reliable interface with legacy 74LS/74ALS logic without pull-ups. |
| Overvoltage-Tolerant I/O | Withstands −0.5 V to +7.0 V on IN A and OUT Y independent of VCC - eliminates need for external clamping diodes in mixed-supply systems. |
| Ultra-Fast Enable/Disable | tPZL/tPLZ = 4.8 ns (typ) @ 5.0 V - enables precise timing control in multiplexed bus architectures with minimal dead-time overhead. |
| Low Quiescent Current | ICC ≤ 2.0 µA (max) at TA = 25 °C - supports always-on monitoring circuits in battery-backed industrial sensors. |
| Thermal Robustness | Rated for TJ ≤ 150 °C and MSL Level 1 - suitable for reflow soldering and sustained operation in sealed enclosures without forced cooling. |

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 |
|---|---|---|---|
| SN74LVC1G126DBVR | Same UDFN6 package (1.45 × 1.0 mm), but 0.5 mm pitch; slightly higher ICC (10 µA max); identical VCC range and drive strength. | Marginally larger footprint; requires updated stencil aperture for assembly; same functional behavior in 3.3 V systems. | Select if existing design uses TI's 1.45 mm variant and board rework is impractical. |
| 74LVC1G125GW,125 | Inverting buffer (Y = NOT A); otherwise identical specs, package (TSSOP5), and temperature range. | Requires logic inversion in upstream firmware or external gate; unsuitable where signal polarity must be preserved. | Choose only when system architecture accommodates inverted control signals and TSSOP5 footprint is acceptable. |
Compared with SN74LVC1G126DBVR and 74LVC1G125GW,125, the NLU1GT126MUTCG offers the smallest PCB footprint (1.2 × 1.0 mm), lowest quiescent current (2 µA max), and superior overvoltage tolerance - making it optimal for miniaturized, mixed-voltage, and thermally demanding applications where pin-for-pin replacement is not required.

FAQ
What is the maximum operating temperature for the NLU1GT126MUTCG?
The NLU1GT126MUTCG is rated for continuous operation from −55 °C to +125 °C ambient temperature, with junction temperature limited to 150 °C. This specification is validated per JEDEC JESD22-A104 and applies across the full 1.65–5.5 V VCC range. The device maintains specified timing and DC parameters throughout this range, making NLU1GT126MUTCG suitable for under-hood automotive and industrial environments where thermal cycling is severe.
Does the NLU1GT126MUTCG require external pull-up or pull-down resistors on its inputs?
No, the NLU1GT126MUTCG does not require external pull-up or pull-down resistors on IN A or OE. Its inputs feature internal biasing that meets LSTTL-compatible thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 5.0 V) without external components. However, OE should be actively driven - floating OE is undefined and may cause unintended output states. For fail-safe operation, tie OE to GND via a 10 kΩ resistor if not actively controlled.
Can the NLU1GT126MUTCG safely interface a 5 V sensor output with a 1.8 V microcontroller input?
Yes, the NLU1GT126MUTCG can safely interface a 5 V sensor output to a 1.8 V microcontroller input - but only when used as a level translator in the direction sensor → MCU. Its inputs tolerate up to 7.0 V regardless of VCC, so applying 5 V to IN A while VCC = 1.8 V is electrically safe. However, the output (OUT Y) swings from 0 V to VCC (1.8 V), which is compatible with 1.8 V logic inputs. Thus, NLU1GT126MUTCG enables robust 5 V-to-1.8 V unidirectional translation without external components.
What is the recommended PCB layout practice for the thermal pad on the NLU1GT126MUTCG UDFN6 package?
The NLU1GT126MUTCG UDFN6 package includes an exposed copper thermal pad on the bottom surface (case 517AA), which is not internally connected. Per onsemi's layout guidelines, this pad should be soldered to a dedicated thermal land on the PCB - typically a solid copper pour connected to GND via ≥4 thermal vias (0.3 mm diameter, spaced ≤1 mm apart). Do not connect the pad to VCC or leave it floating; proper grounding improves heat dissipation and reduces ground bounce during fast switching transitions of NLU1GT126MUTCG.
Is the NLU1GT126MUTCG pin-compatible with other devices in the NLU1GTxxx MiniGate family?
No, the NLU1GT126MUTCG is not pin-compatible with other NLU1GTxxx variants such as NLU1GT04 or NLU1GT32. While all share the UDFN6 footprint, pin assignments differ: NLU1GT126MUTCG uses pins 1=GND, 2=OE, 3=IN A, 4=NC, 5=OUT Y, 6=VCC; NLU1GT04 (inverter) assigns pin 2 to IN A and pin 5 to OE. Substituting without layout revision will result in incorrect functionality or damage. Always verify pin mapping against the specific device's datasheet before board reuse.
