onsemi NLU1GT04MUTCG

Overview

NLU1GT04MUTCG from onsemi is a single high-speed CMOS inverting buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for logic-level translation and signal inversion in space-constrained applications. It operates from 1.65 V to 5.5 V, delivers 3.8 ns typical propagation delay at 5.0 V, supports ±12.5 mA output drive, and features input/output overvoltage tolerance up to 7 V independent of supply voltage - used in industrial sensor interface and low-power microcontroller I/O buffering.

For engineers reviewing the NLU1GT04MUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6 ultra-small footprint (1.45 × 1.0 mm), LSTTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V at VCC = 5.5 V), rail-to-rail CMOS output capability, and built-in power-down input protection for hot-swap and partial-power-down systems.

Technical Context

The NLU1GT04MUTCG implements a single-stage CMOS inverter with balanced rise/fall propagation delays and input structures rated for −0.5 V to +7.0 V, enabling robust operation across mixed-voltage domains. Its input threshold alignment with LSTTL ensures compatibility with legacy 5 V logic while maintaining low ICC (1.0 µA max at TA = 25°C) under static conditions.

Output drive strength is specified at ±12.5 mA with VOL < 0.1 VCC and VOH > 0.8 VCC under load, supporting direct interfacing to standard CMOS and TTL loads. The device meets Level 1 MSL rating and is Pb-free, halogen-free, and RoHS compliant per onsemi's manufacturing standards.

FAQ

What is the maximum operating temperature range for the NLU1GT04MUTCG?

The NLU1GT04MUTCG is rated for continuous operation from −55°C to +125°C ambient temperature, meeting extended industrial and automotive under-hood requirements. This specification is validated per JEDEC JESD22-A108 and confirmed in the Recommended Operating Conditions table of the official datasheet. The NLU1GT04MUTCG maintains full functionality across this range without derating, provided PCB thermal design complies with onsemi's UDFN6 mounting guidelines.

Does the NLU1GT04MUTCG support 1.8 V logic systems?

Yes, the NLU1GT04MUTCG supports 1.8 V logic systems with guaranteed operation down to VCC = 1.65 V. At 1.8 V supply, it delivers valid CMOS output levels (VOH > 1.44 V, VOL < 0.18 V) and meets input thresholds (VIL ≤ 0.3 V, VIH ≥ 0.53 V). The NLU1GT04MUTCG also retains 7 V overvoltage tolerance on I/O pins regardless of supply voltage, enabling safe use in mixed-supply domains.

Are the NC pins on the NLU1GT04MUTCG required to be grounded?

No, the NC pins (pins 2 and 4) on the NLU1GT04MUTCG are unconnected internally and must remain floating or be left unbonded on the PCB - grounding them is not required and may introduce parasitic coupling. The official onsemi datasheet explicitly states these terminals have no electrical function. The NLU1GT04MUTCG's thermal pad is also non-electrical and may be left unconnected unless used for mechanical anchoring per IPC-7351B land pattern recommendations.

Can the NLU1GT04MUTCG be used in hot-swap applications?

Yes, the NLU1GT04MUTCG supports hot-swap operation due to its power-down input protection feature and 7 V input overvoltage tolerance. When VCC = 0 V, inputs remain high-impedance and cannot back-drive the supply rail. This behavior is verified per JEDEC JESD78 latch-up testing and documented in the Absolute Maximum Ratings table. The NLU1GT04MUTCG is therefore suitable for live-insertion scenarios in modular industrial backplanes and field-replaceable units.

What is the meaning of "MUTCG" in the NLU1GT04MUTCG part number?

The suffix "MUTCG" in NLU1GT04MUTCG denotes a specific packaging and compliance configuration: MU = UDFN6 package (Case 517AQ), T = tape-and-reel packaging, C = lead-free (Pb-free) construction, and G = RoHS-compliant and halogen-free/BFR-free material set. This full ordering code is defined in the "Ordering Information" section of the NLU1GT04 datasheet (Rev. 3, June 2016), and confirms the NLU1GT04MUTCG meets IPC/JEDEC standard J-STD-020 for moisture sensitivity Level 1.
