Product details
Overview
NLU3G16BMX1TCG from onsemi is a triple non-inverting buffer IC in ULLGA8 (1.95 × 1.0 mm) package, designed for high-speed signal buffering in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 3.5 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features overvoltage-tolerant (OVT) I/O pins up to 7.0 V - enabling robust interfacing between mixed-voltage domains in industrial control logic.
For engineers reviewing the NLU3G16BMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its ultra-small ULLGA8 footprint, OVT input/output capability across supply voltages, balanced tPLH/tPHL timing, power-down input protection, and guaranteed operation from −55°C to +125°C in automotive and industrial environments.
Technical Context
The NLU3G16BMX1TCG implements three independent CMOS non-inverting buffers with rail-to-rail input voltage tolerance (−0.5 V to +7.0 V), decoupled from VCC. Its input structures include power-down protection diodes that remain functional even when VCC = 0 V, preventing back-powering and latch-up during hot-insertion or partial-power-down scenarios.
Each buffer provides symmetrical rise/fall propagation delays (tPLH ≈ tPHL), low input capacitance (10 pF max), and stable DC output levels (VOH ≥ 2.48 V at 3.0 V VCC, IOL = 4 mA; VOL ≤ 0.44 V under same conditions), supporting clean signal integrity in high-density PCB routing and multi-load fanout configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters |
| tPD (Typ) | 3.5 ns @ VCC = 5.0 V, CL = 15 pF - ensures sub-4 ns timing for high-throughput digital control paths |
| IO Max | ±12.5 mA - drives multiple standard CMOS loads (e.g., ≥10 74LVC inputs) without external buffering |
| VIN/VOUT Tolerance | −0.5 V to +7.0 V - allows safe connection to higher-voltage peripherals or legacy systems without clamping diodes |
| Operating Temp | −55°C to +125°C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| ICC (Max) | 10 µA @ TA = 25°C - minimizes quiescent current impact in always-on monitoring circuits |
| CIN (Max) | 10 pF - reduces capacitive loading on upstream drivers and improves signal edge fidelity |
Pinout & Package
ULLGA8 package (1.95 × 1.0 mm, 0.5 mm pitch), 8-terminal leadless land grid array with exposed thermal pad (non-electrical). Pin 1 marked by chamfered corner; bottom-side thermal pad enhances thermal dissipation in high-density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN A1 | Input of Buffer 1 - accepts OVT logic signals; internally protected against overvoltage regardless of VCC state |
| 2 | OUT Y3 | Output of Buffer 3 - drives downstream logic with matched VOH/VOL and low output impedance |
| 3 | IN A2 | Input of Buffer 2 - electrically isolated from other inputs; supports independent enable/disable sequencing |
| 4 | GND | Ground reference - dedicated return path for all internal logic and output stages; must be low-impedance |
| 5 | OUT Y2 | Output of Buffer 2 - symmetric timing to Y1/Y3; supports parallel bus buffering with skew < 0.5 ns |
| 6 | IN A3 | Input of Buffer 3 - tolerant of floating or undriven states due to internal weak pull-down during power-down |
| 7 | OUT Y1 | Output of Buffer 1 - configured for direct connection to microcontroller GPIOs or FPGA I/O banks |
| 8 | VCC | Positive supply - powers all three buffers; requires local 100 nF ceramic decoupling within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-Tolerant I/O | Supports 7.0 V input/output swing independent of VCC - eliminates need for external voltage translators in mixed-supply systems |
| Power-Down Input Protection | Inputs remain high-impedance and non-latching when VCC = 0 V - prevents backfeeding and system-level fault propagation |
| Balanced Propagation Delays | tPLH and tPHL match within 0.3 ns across temperature - critical for synchronous clock distribution and data strobe alignment |
| Ultra-Small ULLGA8 Footprint | 1.95 × 1.0 mm area with 0.5 mm pitch - saves >60% board space vs. SOIC-8 while maintaining thermal performance |
| Pb-Free & RoHS Compliant | Meets J-STD-020 moisture sensitivity Level 1 - supports lead-free reflow without preconditioning or special handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple non-inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G16DCUR | SO-8 package (2.95 × 2.8 mm); no OVT - max VIN = VCC + 0.5 V; tPD = 3.8 ns @ 3.3 V | Requires external clamping for >3.3 V interfaces; unsuitable for hot-swap or partial-power-down systems | Select when board space is not constrained and all interfaced logic remains within same VCC domain |
| 74LVC1G16FW4-7 | Single-channel SOT-353; requires three units for equivalent functionality; tPD = 3.2 ns @ 3.3 V | Higher assembly cost and layout complexity due to three separate placements and routing; no shared ground/power pins | Select only when modularity or incremental channel enable/disable is required per buffer |
Compared with SN74LVC3G16DCUR and 74LVC1G16FW4-7, the NLU3G16BMX1TCG uniquely combines triple buffering, OVT I/O, ULLGA8 miniaturization, and power-down safety - making it optimal for space-limited, mixed-voltage, and fail-safe industrial designs where single-part integration reduces risk and test overhead.

FAQ
What is the maximum input voltage rating for the NLU3G16BMX1TCG?
The NLU3G16BMX1TCG supports DC input voltages from −0.5 V to +7.0 V on all I/O pins, independent of VCC level. This overvoltage tolerance is confirmed in the Maximum Ratings table (VIN parameter) and applies across the full operating temperature range. The NLU3G16BMX1TCG maintains this rating even when VCC = 0 V, thanks to integrated protection diodes and power-down-safe input circuitry.
Does the NLU3G16BMX1TCG require external pull-up or pull-down resistors on its inputs?
No, the NLU3G16BMX1TCG does not require external pull-up or pull-down resistors on its inputs. Its inputs feature internal weak pull-downs active during power-down (VCC = 0 V), and the CMOS structure ensures stable logic states with driven inputs. External resistors are unnecessary unless specific system-level biasing or fail-safe default states are mandated by the host design - which is not a requirement of the NLU3G16BMX1TCG itself.
Can the NLU3G16BMX1TCG operate reliably at −55°C?
Yes, the NLU3G16BMX1TCG is fully specified and tested for operation from −55°C to +125°C, as stated in the Recommended Operating Conditions table. All AC and DC parameters - including propagation delay, VOH/VOL, and ICC - are guaranteed across this full range. The ULLGA8 package's thermal characteristics and onsemi's qualification testing ensure consistent performance in extreme cold environments such as aerospace avionics or polar-deployed instrumentation.
What is the thermal pad on the bottom of the NLU3G16BMX1TCG package used for?
The exposed thermal pad on the underside of the NLU3G16BMX1TCG's ULLGA8 package is a non-electrical mechanical feature designed to improve heat conduction from the die to the PCB. It must be soldered to a thermally enhanced copper pour (ideally connected to internal ground planes via multiple vias) to maintain junction temperature within limits during sustained operation. No electrical connection is required or recommended - the pad is isolated from all internal circuitry per the package drawing (Case 613AC).
Is the NLU3G16BMX1TCG pin-compatible with other variants in the NLU3G16 family?
Yes, the NLU3G16BMX1TCG shares identical pinout and function mapping with all other NLU3G16 variants (e.g., NLU3G16MUTAG, NLU3G16DMUTCG), as confirmed in the Pin Assignment diagram on page 1 of the datasheet. All variants use the same 1–8 pin numbering and signal labeling (IN A1, OUT Y3, GND, etc.), enabling drop-in replacement across UDFN8 and ULLGA8 packages - provided PCB land patterns accommodate the specific footprint dimensions and pitch.
