Product details
Overview
NLU1GT32AMX1TCG from onsemi is a single 2-input OR gate in advanced CMOS technology, designed for high-speed logic interfacing with TTL-compatible inputs and full 5.0 V CMOS output swing. It operates from 1.65 V to 5.5 V, delivers 3.7 ns typical propagation delay at 5.0 V, supports −55°C to +125°C operation, and features input/output overvoltage tolerance up to 7.0 V - used in space-constrained industrial control signal conditioning.
For engineers reviewing the NLU1GT32AMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6 (1.45 × 1.0 mm) ultra-small footprint, guaranteed TTL-level input thresholds (VIL = 0.8 V, VIH = 2.0 V), rail-to-rail CMOS output drive (VOH > 0.8 VCC, VOL < 0.1 VCC), and built-in power-down input protection.
Technical Context
The NLU1GT32AMX1TCG implements a single 2-input positive-logic OR function using optimized CMOS transistor sizing for balanced tPLH/tPHL delays. Its input structure includes clamping diodes and current-limiting resistors enabling safe operation up to 7.0 V regardless of VCC, while the output stage drives ±12.5 mA with rail-swing capability.
Designed for mixed-voltage systems, it supports 1.65–5.5 V supply operation with guaranteed switching across the full temperature range (−55°C to +125°C). Input transition rate limits (0–100 ns/V at 3.3 V; 0–20 ns/V at 5.0 V) ensure robust noise immunity without external hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (positive logic, Y = A + B) |
| Propagation Delay | 3.7 ns typical at VCC = 5.0 V, CL = 15 pF - enables ≥100 MHz toggle rates in clean signal paths |
| Supply Voltage Range | 1.65 V to 5.5 V - interoperable with 1.8 V, 3.3 V, and 5 V logic domains |
| TTL-Compatible Inputs | VIL ≤ 0.8 V, VIH ≥ 2.0 V - directly interfaces legacy 5 V TTL outputs without level shifters |
| Output Drive Strength | ±12.5 mA - sufficient to drive 50 pF loads with <10 ns skew across temperature |
| Input/Output Overvoltage Rating | −0.5 V to +7.0 V - protects against transient coupling or hot-swap stress without external clamps |
| Quiescent Current | 2.0 µA max at TA = 25°C - supports always-on monitoring nodes in low-power systems |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), case 517AQ, exposed thermal pad, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all I/O and internal circuitry; 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 | First logic input; identical electrical characteristics to Pin 2; supports asynchronous assertion |
| 4 | NC | No connect - floating terminal; no internal connection; must remain unconnected |
| 5 | OUT Y | OR output; full CMOS swing (VOH > 0.8 VCC, VOL < 0.1 VCC); drives capacitive loads up to 50 pF |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-small UDFN6 footprint | 1.45 × 1.0 mm area - reduces PCB real estate by >60% vs. SOT-23-6 in dense signal routing |
| Balanced propagation delays | tPLH ≈ tPHL within 0.5 ns - minimizes duty-cycle distortion in clocked OR applications |
| Power-down input protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents back-driving during partial power-up |
| Full 5.0 V CMOS output swing | VOH > 4.4 V, VOL < 0.36 V at IO = ±2 mA - ensures noise margin >0.7 V in 5 V systems |
| Latch-up immunity | ±500 mA per JESD78 Class II - withstands ESD and transient overstress without functional interruption |

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 | Same 1.65–5.5 V range but higher ICC (10 µA typ), no 7.0 V overvoltage tolerance, SOT-23-5 package (larger footprint) | Lacks input overvoltage protection; requires external clamps in harsh environments | Select when cost is primary and board space is not constrained; avoid in automotive or industrial transients |
| 74AUP1G32GW,125 | Lower VCC min (0.8 V), lower drive (±4 mA), smaller UDFN6 (1.0 × 1.0 mm), but only rated to 5.5 V absolute max on I/O | Not suitable for systems where inputs may exceed VCC (e.g., hot-swap, mixed-rail coupling) | Prefer for ultra-low-power battery apps below 1.2 V; avoid where 7.0 V input robustness is required |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the NLU1GT32AMX1TCG uniquely combines 7.0 V input tolerance, ultra-small 1.45 × 1.0 mm UDFN6, and sub-4 ns propagation delay - making it optimal for space- and reliability-critical industrial and automotive signal aggregation.

FAQ
What is the maximum supply voltage rating for the NLU1GT32AMX1TCG?
The NLU1GT32AMX1TCG has an absolute maximum DC supply voltage (VCC) rating of +7.0 V, as specified in the Maximum Ratings table. However, recommended operation is limited to 1.65 V to 5.5 V per the Recommended Operating Conditions. Exceeding 5.5 V during normal operation risks violating AC timing specs and long-term reliability, even though the device will not immediately fail at 6.0–7.0 V.
Does the NLU1GT32AMX1TCG support true 1.8 V logic operation?
Yes, the NLU1GT32AMX1TCG fully supports 1.8 V operation: VCC min is 1.65 V, VIH is guaranteed ≤ 0.53 V at 1.8 V (well below typical 1.8 V logic high threshold of ~1.2 V), and VOH exceeds 1.4 V at IOH = −2 mA - ensuring robust interoperability with standard 1.8 V CMOS outputs and inputs.
Is Pin 4 (NC) required to be grounded or left floating on the NLU1GT32AMX1TCG?
Pin 4 is explicitly designated as "NC" (No Connect) in the official datasheet pin assignment and marking diagrams. It has no internal connection and must remain unconnected - neither grounded nor tied to VCC. Routing a trace to this pad or soldering it to copper violates the device's qualified mounting footprint and may cause mechanical stress or thermal imbalance.
How does the NLU1GT32AMX1TCG handle input voltages exceeding VCC?
The NLU1GT32AMX1TCG guarantees safe operation with input voltages from −0.5 V to +7.0 V regardless of VCC value, due to integrated input protection structures. This allows direct connection to 5 V signals even when powered from 3.3 V or 1.8 V, eliminating external level-shifting components in mixed-voltage designs.
What is the thermal pad on the bottom of the NLU1GT32AMX1TCG package used for?
The exposed copper thermal pad on the underside of the NLU1GT32AMX1TCG's UDFN6 package is electrically isolated and intended solely for thermal conduction - it must be soldered to a dedicated PCB thermal pad connected to a ground or power plane via multiple vias. It is not connected to any internal node and provides no electrical function.
