onsemi NLV27WZ14DFT2G

Overview

NLV27WZ14DFT2G from onsemi is a dual Schmitt-trigger inverter IC operating from 1.65 V to 5.5 V, delivering 3.2 ns propagation delay at 5 V, ±32 mA output drive capability, and overvoltage-tolerant inputs/outputs up to 5.5 V. It serves as a noise-immune signal conditioning and waveform shaping element in low-voltage digital interface circuits.

For engineers reviewing the NLV27WZ14DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility (1.65–5.5 V), Schmitt-trigger hysteresis for noisy environments, IOFF partial power-down support, and SC-88 package suitability for space-constrained PCB layouts.

Technical Context

The NLV27WZ14DFT2G integrates two independent Schmitt-trigger inverters with input hysteresis (0.1–1.7 V depending on VCC) to reject noise on slow-rising or noisy logic signals. Its IOFF feature disables output leakage during partial power-down, preventing back-driving of powered rails.

It supports rail-to-rail input operation up to 5.5 V regardless of VCC level and delivers robust output drive: VOL ≤ 0.55 V at IOL = 32 mA (VCC = 4.5 V), VOH ≥ 3.8 V at IOH = −32 mA (VCC = 4.5 V). Thermal resistance is 377 °C/W in SC-88 packaging.

FAQ

What is the maximum input voltage the NLV27WZ14DFT2G can tolerate?

The NLV27WZ14DFT2G accepts DC input voltages up to 5.5 V regardless of VCC level, enabling direct connection to 5 V peripherals even when powered from 1.8 V or 2.5 V supplies. This overvoltage tolerance eliminates external level-shifting components in mixed-voltage systems and is confirmed in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V).

Does the NLV27WZ14DFT2G support partial power-down operation?

Yes, the NLV27WZ14DFT2G implements IOFF circuitry that disables output leakage when VCC = 0 V. This prevents current backflow into powered sections of the system during standby or hot-swap conditions. Measured IOFF leakage is ≤10 µA at 5.5 V, as specified in the DC Electrical Characteristics table under "Power Off Leakage Current".

What is the typical propagation delay of the NLV27WZ14DFT2G at 3.3 V supply?

At VCC = 3.3 V with RL = 1 MΩ and CL = 15 pF, the NLV27WZ14DFT2G exhibits a typical propagation delay (tPLH/tPHL) of 3.3 ns, as listed in the AC Electrical Characteristics table. This value reflects high-speed performance while maintaining Schmitt-trigger noise immunity-critical for timing-sensitive signal conditioning in real-time control loops.

Is the NLV27WZ14DFT2G pin-compatible with other dual Schmitt-trigger inverters in SC-88 packages?

No documented pin-to-pin compatibility exists between NLV27WZ14DFT2G and other SC-88 dual Schmitt-trigger inverters such as SN74LVC2G14DBVR or MC74VHC14DT-their pin assignments differ significantly (e.g., VCC/GND positions vary). Always verify pinout against the specific device's datasheet before PCB layout; NLV27WZ14DFT2G uses Pin 1=A2, Pin 2=A1, Pin 3=GND, Pin 4=VCC, Pin 5=Y2, Pin 6=Y1.

What is the operating temperature range of the NLV27WZ14DFT2G?

The NLV27WZ14DFT2G is rated for continuous operation from −55 °C to +125 °C, as defined in the Recommended Operating Conditions table. This extended range aligns with automotive under-hood and industrial control cabinet requirements and is validated through onsemi's qualification testing-shared with the AEC-Q100-certified NL27WZ14DFT2G−Q variant.
