onsemi NLX3G16DMUTCG

Overview

NLX3G16DMUTCG from onsemi is a triple non-inverting buffer IC designed for high-speed signal conditioning in space-constrained digital systems. It operates across 1.65 V to 5.5 V supply, delivers 1.8 ns typical propagation delay at 5.0 V, supports ±24 mA output drive, and features overvoltage-tolerant (OVT) I/O pins rated to 7.0 V - enabling robust level-shifting between mixed-voltage domains in industrial control logic.

For engineers reviewing the NLX3G16DMUTCG datasheet, pinout, applications, or equivalent options, this device is evaluated for low-latency bus buffering, voltage-level translation in FPGA I/O interfaces, and noise-immune signal fanout in automotive body electronics and portable instrumentation where ultra-small UDFN8 packaging and rail-to-rail input tolerance are critical selection criteria.

Technical Context

The NLX3G16DMUTCG implements three independent CMOS buffer stages with matched input/output structures, each supporting full 7.0 V overvoltage tolerance regardless of VCC. Its design enables operation across wide supply ranges (1.65–5.5 V) while maintaining balanced tPLH/tPHL delays and rail-compatible VIH/VIL thresholds (0.7×VCC / 0.3×VCC).

AC performance is characterized under defined load conditions: 1.8 ns typical tPD at VCC = 5.0 V with RL = 1 MΩ and CL = 15 pF; propagation delay degrades predictably with lower VCC and higher capacitive loading, down to 0.5 ns min at 4.5–5.5 V under light load.

FAQ

What is the maximum input voltage the NLX3G16DMUTCG can tolerate?

The NLX3G16DMUTCG supports DC input voltages from −0.5 V to +7.0 V on all I/O pins, regardless of the applied VCC voltage. This overvoltage tolerance is confirmed per the Absolute Maximum Ratings table in the official onsemi datasheet (Publication Order Number NLX3G16/D), allowing safe interfacing with signals exceeding the supply rail - such as 5 V signals into a 3.3 V system - without external protection circuitry. The NLX3G16DMUTCG maintains this rating across its full operating temperature range.

Does the NLX3G16DMUTCG require external pull-up or pull-down resistors on unused inputs?

No, the NLX3G16DMUTCG does not require external biasing on unused inputs. Its CMOS input structure exhibits negligible leakage (±0.1 µA typical), and floating inputs are electrically stable due to internal gate oxide isolation. However, for best noise immunity and predictable logic state in high-noise environments, onsemi recommends tying unused inputs to VCC or GND. This guidance applies equally to all three channels of the NLX3G16DMUTCG and is consistent with standard CMOS design practice.

What is the thermal performance of the NLX3G16DMUTCG in its UDFN8 package?

The NLX3G16DMUTCG in the UDFN8 (1.95 × 1.0 mm, Case 517CA) package has a junction-to-ambient thermal resistance (θJA) of approximately 220°C/W when mounted on a standard 2-layer FR-4 board with minimum copper pads, as measured per JEDEC JESD51-7. At maximum rated ICC (10 µA) and worst-case ambient temperature (+125°C), self-heating remains below 0.1°C - confirming negligible thermal impact. This makes the NLX3G16DMUTCG suitable for thermally dense layouts without heatsinking.

Can the NLX3G16DMUTCG be used for bidirectional signal translation?

No, the NLX3G16DMUTCG is a unidirectional non-inverting buffer only - it does not support bidirectional operation. Each channel has dedicated input (e.g., IN A1) and output (e.g., OUT Y1) pins with no internal direction control or bus-hold circuitry. For bidirectional level translation, a purpose-built device such as the NTB010x series or PCA9306 is required. The NLX3G16DMUTCG's fixed input→output topology is explicitly defined in its Function Table and Logic Symbol in the onsemi datasheet.

Is the NLX3G16DMUTCG pin-compatible with other members of the NLX3Gxx family?

No, the NLX3G16DMUTCG is not pin-compatible with other NLX3Gxx variants such as NLX3G00 or NLX3G04. While all share the same UDFN8 package outline, pin assignments differ significantly: NLX3G16DMUTCG uses Pins 1/2/6 for inputs and Pins 3/4/7 for outputs, whereas NLX3G00 (dual 2-input NAND) allocates pins for multiple inputs per gate and shared outputs. This functional and physical mismatch means direct substitution would cause logic failure. Always verify pin mapping using the specific device's datasheet before layout reuse.
