onsemi NLV74VHC1G01DFT1G

Overview

NLV74VHC1G01DFT1G from onsemi is a single 2-input NAND gate with open-drain output, designed for level-shifting and wired-OR logic in mixed-voltage systems. It operates from 2.0 V to 5.5 V, delivers 3.5 ns propagation delay at 5 V (typ), supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V - enabling reliable interfacing between 3 V and 5 V domains in industrial control I/O modules.

For engineers reviewing the NLV74VHC1G01DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include open-drain compatibility with I²C bus pull-up networks, IOFF partial power-down protection for hot-swap subsystems, and AEC-Q100 qualification for automotive body electronics integration.

Technical Context

This device implements standard CMOS NAND logic with an open-drain output stage, requiring external pull-up for high-level assertion. Its input structure tolerates voltages up to 5.5 V independent of VCC, allowing safe connection to higher-voltage signal sources even when powered at 2.0 V.

The IOFF feature disables input/output leakage paths when VCC = 0 V, preventing back-powering of inactive rails during partial power-down sequences. Propagation delays are specified across −55 °C to +125 °C and support both 15 pF and 50 pF load conditions per JEDEC AC test standards.

FAQ

What is the logic function and output type of NLV74VHC1G01DFT1G?

NLV74VHC1G01DFT1G implements a standard 2-input NAND logic function with an open-drain output stage. Its truth table shows Y = LOW only when both A and B are HIGH; otherwise, Y is in high-impedance state. This requires an external pull-up resistor to assert HIGH, enabling wired-OR configurations and I²C bus compatibility. The open-drain architecture is confirmed in the datasheet's logic symbol, pinout diagram, and DC output characteristics table.

Does NLV74VHC1G01DFT1G support mixed-voltage interfacing, and how is this achieved?

Yes, NLV74VHC1G01DFT1G supports mixed-voltage interfacing via over-voltage tolerant inputs and outputs rated from −0.5 V to +5.5 V, independent of VCC. This allows connecting 5 V signal sources directly to its inputs while operating at 2.0 V–3.3 V, and driving 5 V pull-up networks from its open-drain output. The feature is validated in the Maximum Ratings and Recommended Operating Conditions tables, and explicitly cited in the datasheet's "interface 5 V circuits to 3 V circuits" application note.

Is NLV74VHC1G01DFT1G qualified for automotive applications?

Yes, NLV74VHC1G01DFT1G is AEC-Q100 qualified (Grade 1: −40 °C to +125 °C) and PPAP capable, as stated in the datasheet's Features section and Ordering Information footnote. The "−Q" suffix variant (e.g., NLV74VHC1G01DFT1G−Q) denotes automotive-specific site and control change requirements. Standard NLV74VHC1G01DFT1G shares the same die and qualification - confirmed by identical parametric limits, thermal resistance values, and operating temperature ranges across both variants.

What is the purpose and behavior of IOFF in NLV74VHC1G01DFT1G?

IOFF in NLV74VHC1G01DFT1G disables input and output leakage paths when VCC = 0 V, preventing current from flowing into or out of the device during partial power-down states. This protects powered-down supply domains from being back-fed by active signals on A, B, or Y pins. The datasheet specifies IOFF leakage ≤10 µA at 0 V VCC and confirms functionality in both DC Electrical Characteristics tables and the Technical Context description of "partial power down protection."

Which package does NLV74VHC1G01DFT1G use, and what are its mechanical identifiers?

NLV74VHC1G01DFT1G uses the SC-88A package (also known as SOT-353), case number 419A, with 5 pins and 0.65 mm pitch. Its dimensions are 2.1 mm × 1.25 mm × 0.95 mm (L × W × H), and it carries the "DF" suffix per onsemi's ordering nomenclature. The package is documented in the Mechanical Case Outline section (Issue M, 11 APR 2023) and confirmed in the Ordering Information table where NLV74VHC1G01DFT1G maps to SC-88A with "V0" specific device code and "Q2" pin 1 orientation.
