Product details
Overview
NLU1GT32MUTCG from onsemi is a single 2-input OR gate in ultra-small UDFN6 (1.2 × 1.0 mm) package, designed for space-constrained logic interfacing. It features TTL-compatible inputs (VIL = 0.8 V, VIH = 2.0 V), full 5.0 V CMOS output swing (VOH > 4.4 V, VOL < 0.36 V @ 2 mA), 3.7 ns typical propagation delay at 5.0 V, and ±12.5 mA output drive - enabling direct replacement of legacy LSTTL gates in battery-powered IoT sensors and portable industrial controllers.
For engineers reviewing the NLU1GT32MUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 1.65–5.5 V wide supply range, input/output overvoltage tolerance up to 7.0 V, ultra-low ICC ≤ 2 µA (max) at 25°C, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive body electronics and medical wearable signal conditioning.
Technical Context
The NLU1GT32MUTCG implements a CMOS-based OR logic function with balanced tPLH/tPHL propagation delays and power-down input protection that prevents current flow when VCC = 0 V. Its input structure accepts TTL-level signals while driving full-rail CMOS outputs, eliminating level-shifting circuitry in mixed-voltage systems.
It operates across −55°C to +125°C with guaranteed performance at 1.65 V minimum supply, supports 100 ns/V input transition rates, and maintains VOH ≥ 2.9 V and VOL ≤ 0.44 V under 4 mA load at 3.0 V - making it suitable for 3.3 V microcontroller I/O expansion and low-power sensor hub aggregation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate - performs Boolean Y = A + B; no internal pull-ups or latching. |
| Propagation Delay | tPD = 3.7 ns (typ) @ VCC = 5.0 V, CL = 15 pF - enables sub-100 MHz clock-domain interfacing. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V logic families without voltage translation. |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - fully compatible with standard TTL and 5 V CMOS input levels. |
| Output Drive | ±12.5 mA sink/source - sufficient to drive multiple 74LVC inputs or LED indicators directly. |
| Overvoltage Tolerance | Inputs/outputs withstand −0.5 V to +7.0 V independent of VCC - protects against hot-plug transients and bus contention. |
| Quiescent Current | ICC ≤ 2 µA (max) @ TA = 25°C - enables always-on wake-up logic in ultra-low-power sleep modes. |
Pinout & Package
Package: UDFN6 (1.2 mm × 1.0 mm, 0.4 mm pitch), case 517AA, exposed thermal pad, Pb-free, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all I/O and internal logic; must be connected to system ground plane. |
| 2 | IN B | Second logic input; accepts TTL- or CMOS-level signals; internally protected to 7.0 V. |
| 3 | IN A | Primary logic input; identical electrical characteristics to IN B; no priority or enable function. |
| 4 | NC | No connect - internally unconnected silicon; must be left floating or tied to GND per layout best practice. |
| 5 | OUT Y | Inverted OR output (Y = A + B); rail-to-rail CMOS swing; capable of sourcing/sinking 12.5 mA. |
| 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 | Validates logic HIGH at VIH = 2.0 V and LOW at VIL = 0.8 V - eliminates need for external resistive biasing when interfacing with legacy 5 V microcontrollers. |
| Full 5.0 V CMOS output swing | VOH > 4.4 V and VOL < 0.36 V @ 2 mA load - ensures noise margin > 0.7 V in 5 V systems and reliable fan-out to 10+ LVTTL loads. |
| Input overvoltage tolerance | Withstands −0.5 V to +7.0 V on IN A/IN B regardless of VCC state - enables safe operation during power sequencing or ESD events. |
| Power-down protection | Inputs remain high-impedance and non-destructive when VCC = 0 V - prevents back-driving of powered subsystems during partial power-down. |
| Ultra-small UDFN6 footprint | 1.2 mm × 1.0 mm area - reduces PCB real estate by >70% vs. SOIC-6, critical for wearables and miniaturized sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G32DBVR | Wider VCC range (1.65–5.5 V), identical pinout, but lacks 7.0 V input overvoltage tolerance and has higher ICC (10 µA typ). | Preferred for cost-sensitive consumer designs where overvoltage robustness is not required. | Select SN74LVC1G32DBVR only if board-level transient protection is already implemented upstream. |
| MC74VHC1G32DTT1G | Same UDFN6 package, but rated only to 3.6 V VCC max and offers no guaranteed 7.0 V input tolerance; propagation delay ~4.2 ns @ 3.3 V. | Suitable for 3.3 V-only systems with tight budget constraints and no hot-swap requirements. | Choose MC74VHC1G32DTT1G only when operating exclusively below 3.6 V and ambient temperature stays ≤ +85°C. |
Compared with SN74LVC1G32DBVR and MC74VHC1G32DTT1G, the NLU1GT32MUTCG uniquely delivers 7.0 V input overvoltage tolerance across its full −55°C to +125°C operating range while maintaining sub-4 ns delay and <2 µA quiescent current - making it the only choice for ruggedized industrial and automotive edge nodes requiring both reliability and ultra-low power.

FAQ
What is the maximum operating temperature range for the NLU1GT32MUTCG?
The NLU1GT32MUTCG is specified for continuous operation from −55°C to +125°C ambient temperature, with full DC and AC performance guaranteed across this range per the Recommended Operating Conditions table. This makes the NLU1GT32MUTCG suitable for under-hood automotive applications and industrial environments where thermal extremes are common.
Does the NLU1GT32MUTCG require external pull-up or pull-down resistors on its inputs?
No, the NLU1GT32MUTCG does not require external pull-up or pull-down resistors on IN A or IN B. Its inputs have defined TTL-compatible thresholds and internal protection structures; unused inputs must be tied to VCC or GND to prevent floating states, but no external resistors are needed for proper logic operation of the NLU1GT32MUTCG.
Can the NLU1GT32MUTCG safely interface between 3.3 V and 5 V logic domains?
Yes, the NLU1GT32MUTCG can safely interface between 3.3 V and 5 V logic domains. Its inputs accept VIH = 2.0 V (compatible with 3.3 V logic HIGH) and tolerate up to 7.0 V, while its outputs swing rail-to-rail - delivering VOH > 4.4 V at 5 V supply and VOH > 2.9 V at 3.0 V supply, ensuring interoperability with both voltage domains without level shifters in the NLU1GT32MUTCG signal path.
Is the exposed thermal pad on the UDFN6 package of the NLU1GT32MUTCG required to be soldered?
Yes, the exposed thermal pad on the NLU1GT32MUTCG UDFN6 package (case 517AA) must be soldered to a PCB thermal pad per the recommended mounting footprint. This connection provides essential thermal dissipation and mechanical stability; omitting it risks exceeding the 150°C junction temperature limit and may cause solder joint fatigue or parametric drift in the NLU1GT32MUTCG.
What is the meaning of "NC" on Pin 4 of the NLU1GT32MUTCG pinout?
"NC" on Pin 4 of the NLU1GT32MUTCG denotes No Connect - the pin is not bonded to any internal circuitry and serves only as a mechanical placeholder. It must be left electrically floating or connected to GND per PCB layout guidelines; connecting it to VCC or a signal line may cause unpredictable behavior or damage the NLU1GT32MUTCG.
