onsemi NLU1GT04AMUTCG

Overview

NLU1GT04AMUTCG from onsemi is a single high-speed CMOS inverting buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, housed in a 1.20 mm × 1.00 mm UDFN6 package. It delivers 3.8 ns typical propagation delay at 5.0 V, supports 1.65–5.5 V supply operation, and features ±12.5 mA output drive-used in level-shifting and signal conditioning within space-constrained industrial control and portable sensor interfaces.

For engineers reviewing the NLU1GT04AMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its ultra-small UDFN6 footprint, 7 V input/output overvoltage tolerance independent of V_CC, TTL-level compatibility at 1.8–5.5 V supplies, and guaranteed latch-up immunity per JESD78 at ±500 mA.

Technical Context

The NLU1GT04AMUTCG implements a single-stage CMOS inverter with robust input protection diodes enabling safe operation up to 7 V on any pin regardless of supply voltage. Its input threshold (V_IL = 0.8 V, V_IH = 2.0 V at V_CC = 5.5 V) ensures reliable interfacing with legacy TTL logic, while output swing (V_OH > 0.8 V_CC, V_OL < 0.1 V_CC) maintains rail-to-rail CMOS compatibility.

Propagation delay is characterized across temperature (−55°C to +125°C) and load (15 pF and 50 pF), with t_PLH/t_PHL = 3.8 ns (typ) at 5.0 V/15 pF. Input capacitance is 10 pF max, and power-down protection prevents back-driving current when V_CC = 0 V.

FAQ

What is the maximum supply voltage for the NLU1GT04AMUTCG?

The NLU1GT04AMUTCG supports a DC supply voltage range of −0.5 V to +7.0 V, with recommended operation between 1.65 V and 5.5 V. This 7.0 V absolute maximum rating applies to V_CC, inputs, and outputs simultaneously-enabling safe operation during power sequencing, hot-swap events, or transient overvoltage conditions without external clamping. The NLU1GT04AMUTCG maintains functional integrity across this full range per JEDEC JESD78 latch-up testing.

Does the NLU1GT04AMUTCG support 1.8 V logic levels?

Yes, the NLU1GT04AMUTCG fully supports 1.8 V operation: V_IL = 0.3 V and V_IH = 1.2 V at V_CC = 1.8 V, meeting standard LVTTL thresholds. Its input structure remains TTL-compatible across 1.65–5.5 V, allowing seamless integration with 1.8 V microcontrollers, FPGAs, and sensor interfaces. The NLU1GT04AMUTCG also delivers rail-swing output (V_OH > 1.44 V, V_OL < 0.18 V) at 1.8 V supply, preserving noise margin.

What is the thermal performance of the NLU1GT04AMUTCG in continuous operation?

The NLU1GT04AMUTCG is rated for continuous operation from −55°C to +125°C junction temperature, with storage temperature spanning −65°C to +150°C. Its UDFN6 package exhibits low thermal resistance (θ_JA ≈ 220°C/W on 2-layer FR4), and quiescent current remains ≤1.0 µA at 25°C and ≤40 µA across full temperature range. The NLU1GT04AMUTCG maintains specified propagation delay and output drive performance across this entire range per AC/DC characterization data.

Can unused pins on the NLU1GT04AMUTCG be left floating?

No-pins 2 and 4 of the NLU1GT04AMUTCG are NC (no-connect) terminals and must not be left floating in production layouts. Per onsemi's design guidance, NC pins should be tied to GND to minimize parasitic coupling, reduce EMI susceptibility, and ensure mechanical stability during reflow. Leaving them unconnected may cause unpredictable behavior in high-frequency or high-noise environments. The NLU1GT04AMUTCG datasheet explicitly recommends grounding NC pins for optimal reliability.

Is the NLU1GT04AMUTCG pin-compatible with other single inverters in UDFN6 packages?

The NLU1GT04AMUTCG uses a non-standard UDFN6 pinout (GND–NC–IN–NC–OUT–V_CC) that differs from industry-common arrangements like SN74LVC1G04DBVR (GND–IN–OUT–V_CC–NC–NC). Therefore, the NLU1GT04AMUTCG is not pin-compatible with other UDFN6 inverters. PCB layout must follow the exact pin mapping shown in Figure 1 of the NLU1GT04AMUTCG datasheet-swapping footprints will result in functional failure or damage.
