Product details
Overview
NLU1GT32CMX1TCG from onsemi is a single 2-input OR gate in ultra-small UDFN6 (1.0 × 1.0 mm) package, designed for space-constrained 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 ±12.5 mA output drive capability.
For engineers reviewing the NLU1GT32CMX1TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its LSTTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), robust 7.0 V absolute maximum input/output voltage tolerance, and power-down input protection - critical for mixed-voltage system interfacing and hot-swap environments.
Technical Context
The NLU1GT32CMX1TCG implements a standard positive-logic OR function (Y = A + B) using advanced CMOS process technology optimized for high speed and low static power. Its input structure includes clamping diodes and ESD protection enabling safe operation up to 7.0 V regardless of VCC, while the output stage provides rail-to-rail CMOS swing with balanced tPLH/tPHL delays.
It supports wide supply range operation (1.65–5.5 V) and maintains specified DC and AC performance across −55°C to +125°C. Input transition rate limits (0–100 ns/V) and guaranteed latch-up immunity (±500 mA per JESD78) ensure robustness in noisy industrial and automotive control signal paths.
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 domains without level shifters. |
| tPD (Typ) | 3.7 ns @ VCC = 5.0 V, CL = 15 pF - supports >100 MHz toggle rates in compact timing-critical paths. |
| VIH / VIL | 2.0 V / 0.8 V @ VCC = 5.0 V - ensures reliable recognition of standard TTL-level signals. |
| VOH / VOL | >4.4 V / <0.36 V @ IOH = −4 mA / IOL = 4 mA - guarantees noise margin >0.7 V in 5 V systems. |
| Input Protection | Withstands −0.5 V to +7.0 V input voltage independent of VCC - eliminates need for external clamping in overvoltage-prone interfaces. |
| Package | UDFN6, 1.0 × 1.0 mm, 0.35 mm pitch - fits within 1.2 mm² board area, ideal for wearables and ultra-dense PCBs. |
Pinout & Package
Package: UDFN6 (1.0 × 1.0 mm, 0.35 mm pitch), case 517BX, exposed thermal pad, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path. |
| 2 | IN B | Second logic input terminal; accepts TTL- and CMOS-level signals up to 7.0 V. |
| 3 | IN A | Primary logic input terminal; electrically identical to IN B with same voltage and current specs. |
| 4 | NC | No connect - internally unconnected; must be left floating or tied to GND per layout best practice. |
| 5 | OUT Y | OR-gate output; drives capacitive loads up to 50 pF with guaranteed timing and voltage levels. |
| 6 | VCC | Positive supply input; decoupling capacitor (0.1 µF) required within 2 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.0 × 1.0 mm UDFN6 package reduces board area by >60% vs. standard SOT-363 logic gates. |
| TTL-compatible inputs | VIL = 0.8 V / VIH = 2.0 V at 5 V allows direct connection to legacy 5 V microcontrollers and bus drivers. |
| Full CMOS output swing | VOH > 0.8 VCC and VOL < 0.1 VCC ensure compatibility with downstream CMOS loads across full VCC range. |
| Input overvoltage tolerance | Inputs withstand −0.5 V to +7.0 V regardless of VCC - enables safe use in mixed-supply systems and hot-plug scenarios. |
| Power-down protection | Inputs remain protected and non-latching when VCC = 0 V - prevents back-powering and damage during partial power-up. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |

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 VCC range, but only rated to +85°C ambient; tPD = 3.8 ns (typ); no 7.0 V input overvoltage tolerance. | Lacks extended temperature support and overvoltage resilience - unsuitable for under-hood or industrial outdoor deployments. | Select SN74LVC1G32DBVR only for cost-sensitive consumer-grade designs operating strictly within commercial temperature range. |
| 74AUP1G32GW,125 | Lower ICC (0.9 µA typ), smaller 1.0 × 1.0 mm XSON6 package, but VIH = 1.9 V min at VCC = 3.3 V - marginal TTL compatibility. | Marginally meets TTL VIH threshold at 3.3 V; not recommended for legacy 5 V TTL source interfacing. | Choose 74AUP1G32GW,125 only when ultra-low static power dominates over input compatibility requirements. |
Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the NLU1GT32CMX1TCG uniquely combines extended temperature rating (−55°C to +125°C), 7.0 V input overvoltage tolerance, and guaranteed TTL-level compatibility - making it the only option qualified for harsh-environment logic aggregation without external protection components.

FAQ
What is the maximum operating temperature range for the NLU1GT32CMX1TCG?
The NLU1GT32CMX1TCG is fully specified from −55°C to +125°C ambient temperature, with DC and AC electrical characteristics guaranteed across this full industrial and automotive under-hood range. This includes validated performance of propagation delay, input thresholds, and output drive strength at both extremes, making the NLU1GT32CMX1TCG suitable for engine control units, industrial motor drives, and outdoor sensor nodes where thermal cycling is severe.
Does the NLU1GT32CMX1TCG require external pull-up or pull-down resistors on its inputs?
No, the NLU1GT32CMX1TCG does not require external pull-up or pull-down resistors on its inputs. Its inputs have defined TTL-compatible thresholds (VIL = 0.8 V, VIH = 2.0 V at 5 V) and include internal ESD protection and clamping structures. When left unconnected, inputs default to a high-impedance state but must be actively driven to avoid undefined logic states - floating inputs are not permitted in functional designs.
Can the NLU1GT32CMX1TCG safely interface with 5 V TTL outputs while powered from a 3.3 V supply?
Yes, the NLU1GT32CMX1TCG can safely interface with 5 V TTL outputs while powered from 3.3 V. Its inputs tolerate voltages from −0.5 V to +7.0 V regardless of VCC, and its VIH specification (1.4 V min at VCC = 3.3 V) is comfortably exceeded by standard 5 V TTL VOH (≥2.4 V). This eliminates the need for external level-shifting circuitry in mixed-voltage signal aggregation tasks.
What is the meaning of "NC" on Pin 4 of the NLU1GT32CMX1TCG?
"NC" on Pin 4 of the NLU1GT32CMX1TCG stands for "No Connect" - this terminal is not bonded internally and has no electrical function. Per onsemi's layout guidance, Pin 4 should be left unconnected (floating) or optionally tied to GND for mechanical stability and improved thermal conduction; it must never be connected to VCC or driven by an external signal.
Is the NLU1GT32CMX1TCG pin-compatible with other UDFN6 logic gates from onsemi?
The NLU1GT32CMX1TCG uses a proprietary pinout (GND/INB/INA/NC/OUTY/VCC) that differs from onsemi's other UDFN6 logic devices such as the NLU1G00 or NLU1G08. While all share the same 1.0 × 1.0 mm 6-pin UDFN package outline (case 517BX), the pin assignments are not interchangeable - PCB layout must be specific to the NLU1GT32CMX1TCG's documented pin mapping to ensure correct functionality.
