Product details
Overview
NLU1GT126AMUTCG 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 features 3.8 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, and operates across −55 °C to +125 °C with supply voltage range 1.65 V to 5.5 V.
For engineers reviewing the NLU1GT126AMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-small UDFN6 (1.45 × 1.0 mm) footprint, 7.0 V input/output overvoltage tolerance, 3-state enable control logic, and LSTTL-level compatibility in low-power CMOS architecture.
Technical Context
The NLU1GT126AMUTCG implements a single non-inverting buffer stage with active-low 3-state output control (OE), where OE = Low enables output and OE = High places Y in high-impedance state. Its input structure accepts TTL thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while delivering rail-to-rail CMOS outputs (VOH > 0.8 VCC, VOL < 0.1 VCC).
Input and output pins are protected against overvoltage up to 7.0 V regardless of VCC, and the device meets Level 1 moisture sensitivity with Pb-free UDFN6 packaging. Propagation delays (tPLH/tPHL) and enable/disable times (tPZL/tPLZ) are characterized across 3.0–3.6 V and 4.5–5.5 V supply ranges with CL = 15 pF and 50 pF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-voltage I/O interfacing across 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains |
| tPD (Typ) | 3.8 ns @ VCC = 5.0 V, CL = 15 pF - enables timing-critical signal buffering in high-speed digital interfaces |
| IO Max | ±12.5 mA - sufficient to drive standard CMOS loads and short PCB traces without external buffering |
| VIN/VOUT Rating | −0.5 V to +7.0 V - allows safe operation during hot-swap, level-shifting, or transient overvoltage conditions |
| ICC (Max) | 20 µA @ TA = 25 °C - ensures ultra-low static power consumption in battery-backed or always-on circuits |
| Package | UDFN6, 1.45 × 1.0 mm, 0.5 mm pitch - fits sub-1.5 mm² board area for portable, wearables, and dense MCU peripheral routing |
| Operating Temp | −55 °C to +125 °C - qualified for automotive under-hood, industrial control, and extended-temperature embedded applications |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), Case 517AQ, Pb-free, moisture sensitivity Level 1. Exposed copper pad for thermal enhancement and mechanical anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for all internal circuitry; must be connected to low-impedance system ground plane |
| 2 - OE | Output enable (active-low) | Drives output Y to high-impedance when logic High; requires pull-down or controlled logic source |
| 3 - IN A | Non-inverting data input | Accepts TTL-level signals; internally clamped to support 7.0 V tolerant operation independent of VCC |
| 4 - NC | No connect | Internally unconnected silicon pad; must remain floating - no external connection permitted |
| 5 - OUT Y | Buffered non-inverting output | Delivers full CMOS swing (VOH > 0.8 VCC, VOL < 0.1 VCC); supports 3-state bus sharing |
| 6 - VCC | Positive supply | Single-supply rail powering all logic and output stages; decoupling capacitor required within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | VIL ≤ 0.8 V and VIH ≥ 2.0 V at 5.0 V - enables direct interface with legacy 74LS/74ALS logic without level shifters |
| 7.0 V overvoltage tolerant I/O | Inputs and outputs withstand −0.5 V to +7.0 V regardless of VCC - eliminates need for external TVS or clamping diodes |
| Ultra-small UDFN6 footprint | 1.45 × 1.0 mm outline with 0.5 mm pitch - reduces PCB area by >50% vs. SOT-363 or SC-70 packages |
| Low dynamic power dissipation | CPD = 14 pF @ 5.0 V - limits switching current to <1 µA/MHz, critical for low-duty-cycle sensor interface nodes |
| Power-down input protection | Input structures remain functional and non-latching even with VCC = 0 V - prevents backfeeding and latch-up during partial power-down |
Applications

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 VCC range, but only 3.0 ns tPD (typ) at 3.3 V; lacks 7.0 V overvoltage tolerance | Better speed at 3.3 V, but requires external clamping for industrial transients | Select when maximum speed at 3.3 V is prioritized over robustness in harsh environments |
| 74AUP1G126GW,125 | Lower ICC (500 nA typ), smaller 1.0 × 1.0 mm UDFN, but only −40 °C to +125 °C rating and 5.5 V absolute max VIO | Superior for ultra-low-power wearables, but not rated for extended cold-temperature industrial use | Select when sub-µA quiescent current dominates design requirements and temperature range is limited |
Compared with SN74LVC1G125DBVR and 74AUP1G126GW,125, the NLU1GT126AMUTCG uniquely combines 7.0 V overvoltage tolerance, extended −55 °C operation, and 1.45 × 1.0 mm package - making it optimal for ruggedized, wide-temperature, space-constrained digital routing where reliability trumps marginal speed gains.

FAQ
What is the function of the NC pin on the NLU1GT126AMUTCG?
The NC (No Connect) pin on the NLU1GT126AMUTCG is an internally unconnected terminal located at position 4. It serves no electrical function and must remain unconnected in the PCB layout. Soldering or routing to this pin may compromise package integrity or thermal performance, and onsemi explicitly prohibits any external connection to Pin 4 per the datasheet marking diagram and mechanical drawings.
Does the NLU1GT126AMUTCG support 1.8 V logic levels?
Yes, the NLU1GT126AMUTCG supports 1.8 V logic operation: its recommended VCC range is 1.65 V to 5.5 V, and DC electrical characteristics (VIH, VIL, VOH, VOL) are specified down to 1.65 V. At 1.8 V supply, it maintains TTL-compatible input thresholds and delivers CMOS-compatible output swing, enabling interoperability with 1.8 V microcontrollers and peripherals.
Is the NLU1GT126AMUTCG pin-compatible with other variants in the NLU1GT126 family?
No - the NLU1GT126AMUTCG uses the UDFN6 1.45 × 1.0 mm package (Case 517AQ), while NLU1GT126MUTCG uses 1.2 × 1.0 mm (Case 517AA) and NLU1GT126CMUTCG uses 1.0 × 1.0 mm (Case 517BX). Though all share identical pinout numbering and function mapping, their physical dimensions and pitch differ, requiring separate PCB footprints and rework for substitution.
What is the maximum capacitive load the NLU1GT126AMUTCG can drive reliably?
The NLU1GT126AMUTCG is characterized for CL = 15 pF and CL = 50 pF loads in AC specifications, with propagation delay increasing from 3.8 ns to 5.3 ns (typ) at 5.0 V. While not explicitly rated beyond 50 pF, its ±12.5 mA output drive and low COUT (6 pF) support stable operation into ≤50 pF loads - larger capacitances require careful signal integrity analysis or local buffering.
How does the NLU1GT126AMUTCG handle power sequencing when VCC is ramped after input signals are applied?
The NLU1GT126AMUTCG incorporates power-down protection: its inputs tolerate voltages from −0.5 V to +7.0 V regardless of VCC state, including VCC = 0 V. This prevents back-driving, latch-up, or damage during asymmetric power-up sequences - a critical feature in modular systems where sensor or interface signals may be present before the buffer's supply is stabilized.
