onsemi NLU1GT04BMX1TCG

Overview

NLU1GT04BMX1TCG from onsemi is a single high-speed CMOS inverting buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, rated for operation from −55 °C to +125 °C, featuring 3.8 ns typical propagation delay at 5.0 V, ±12.5 mA output drive, and input/output protection up to 7 V. It serves as a logic-level translator and signal inverter in space-constrained industrial control and automotive body electronics.

For engineers reviewing the NLU1GT04BMX1TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its UDFN6 ultra-small footprint (1.20 × 1.00 mm), LSTTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V at 5.0 V), rail-to-rail CMOS output capability, and robust ±20 mA I/O diode current rating under overvoltage conditions.

Technical Context

The NLU1GT04BMX1TCG implements a single-stage CMOS inverter with balanced tPLH/tPHL propagation delays and power-down input protection that maintains high-impedance behavior when VCC = 0 V. Its input structure tolerates voltages up to 7 V independent of supply, enabling safe interfacing with mixed-voltage systems.

It operates across 1.65–5.5 V supply range, supports 15 pF and 50 pF load conditions per AC specs, and delivers VOH > 0.8 VCC and VOL < 0.1 VCC under specified loads - confirming true CMOS output compatibility while retaining TTL-level input recognition.

FAQ

What is the maximum operating temperature range for the NLU1GT04BMX1TCG?

The NLU1GT04BMX1TCG is fully specified for continuous operation from −55 °C to +125 °C ambient temperature, with junction temperature limited to 150 °C under bias. This extended range is validated per JEDEC JESD22-A108 and supports deployment in under-hood automotive modules and industrial motor control enclosures where thermal cycling is severe. The NLU1GT04BMX1TCG maintains full DC and AC performance across this range without derating.

Does the NLU1GT04BMX1TCG support 1.8 V logic systems?

Yes, the NLU1GT04BMX1TCG operates down to 1.65 V VCC and delivers valid CMOS output swing (VOH > 0.8 VCC, VOL < 0.1 VCC) at 1.8 V supply. Input thresholds scale accordingly: VIH ≈ 0.53 V and VIL ≈ 0.3 V at 1.8 V, ensuring compatibility with 1.8 V microcontrollers and sensors. The NLU1GT04BMX1TCG retains its 7 V input tolerance even at 1.8 V VCC, enabling safe interfacing with higher-voltage peripherals.

Are the NC pins on the NLU1GT04BMX1TCG required to be grounded or left floating?

The NC pins (pins 2 and 4) on the NLU1GT04BMX1TCG are not internally connected and must be left unconnected - neither grounded nor tied to VCC. Per onsemi's datasheet and package documentation, these terminals are electrically isolated and serve only mechanical or thermal roles in the UDFN6 die attach. Connecting them risks unintended parasitic paths or solder bridging; the NLU1GT04BMX1TCG functions correctly with both NC pins floating.

What is the recommended PCB layout practice for the NLU1GT04BMX1TCG's power supply?

A 100 nF ceramic decoupling capacitor must be placed within 2 mm of the NLU1GT04BMX1TCG's VCC (pin 6) and GND (pin 1), using short, wide traces to minimize inductance. Avoid shared return paths with noisy digital signals. The NLU1GT04BMX1TCG's UDFN6 package has no exposed thermal pad in the 517AA variant, so thermal relief is not required - but ensure ≥0.2 mm solder mask clearance around all pads to prevent bridging. This layout preserves the NLU1GT04BMX1TCG's 3.8 ns propagation delay and prevents ground bounce-induced glitches.

How does the NLU1GT04BMX1TCG's input protection compare to standard CMOS inverters?

The NLU1GT04BMX1TCG features integrated input structures that withstand −0.5 V to +7.0 V regardless of VCC, exceeding standard CMOS inverters (typically limited to GND–VCC). It also includes power-down protection that disables input circuitry when VCC = 0 V, preventing back-current flow. These protections are verified per ESD HBM (>2 kV), MM (>200 V), and latch-up tests (±500 mA). The NLU1GT04BMX1TCG thus eliminates need for external TVS diodes or series resistors in most industrial and automotive signal paths.
