onsemi NLVVHC1G32DFT2G

Overview

NLVVHC1G32DFT2G from onsemi is a single 2-input OR gate IC in SC-88A (SOT-353) package, designed for 2.0 V to 5.5 V operation with CMOS-level input thresholds. It delivers 3.7 ns typical propagation delay at 5 V, supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V-enabling robust 3 V/5 V mixed-supply interfacing in portable logic systems.

For engineers reviewing the NLVVHC1G32DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, propagation delay under load, IOFF partial power-down support, and SC-88A footprint constraints in space-constrained PCB layouts.

Technical Context

This device implements standard positive-logic OR functionality (Y = A + B) using advanced VHC CMOS technology. Its input structure tolerates voltages up to 5.5 V independent of VCC, enabling safe level-shifting between 3 V and 5 V domains without external components.

The output stage supports active-drive capability (±8 mA at 3.0 V) and includes IOFF circuitry that disables I/O leakage when VCC = 0 V-critical for hot-insertion and partial-power-down system architectures where back-driving must be prevented.

FAQ

What is the maximum input voltage rating for NLVVHC1G32DFT2G?

NLVVHC1G32DFT2G supports DC input voltages up to 5.5 V regardless of VCC level-enabling direct connection to 5 V signals even when operating from a 2.0 V or 3.3 V supply. This over-voltage tolerance is implemented via dedicated input protection structures and is explicitly specified in the Absolute Maximum Ratings table of the official onsemi datasheet (Rev. 28, January 2026). The feature eliminates external clamping components in mixed-voltage designs.

Does NLVVHC1G32DFT2G support partial power-down operation?

Yes, NLVVHC1G32DFT2G includes IOFF circuitry that actively disables input and output leakage paths when VCC = 0 V. This prevents back-current flow from live I/O pins into a powered-down section of the system-a requirement for hot-plug and power-sequencing architectures. The IOFF specification is verified across −55 °C to +125 °C and confirmed in the DC Electrical Characteristics table under "Power Off Leakage Current" (IOFF ≤ 10 µA).

What is the propagation delay of NLVVHC1G32DFT2G at 3.3 V operation?

At VCC = 3.3 V and CL = 15 pF, NLVVHC1G32DFT2G exhibits a typical propagation delay (tPLH/tPHL) of 4.8 ns, with a maximum of 9.5 ns over the full operating temperature range (−55 °C to +125 °C). These values are measured from input transition (10%–90%) to output transition (10%–90%) and are documented in the AC Electrical Characteristics table of the onsemi datasheet. Delay increases slightly at higher capacitive loads (e.g., 6.1 ns typ at CL = 50 pF).

Is NLVVHC1G32DFT2G qualified for automotive applications?

Yes, NLVVHC1G32DFT2G is AEC-Q100 qualified and PPAP capable, as indicated by its "−Q" suffix variant (e.g., NLVVHC1G32DFT2G−Q). While the base NLVVHC1G32DFT2G shares identical electrical and thermal specifications with the −Q version, it is manufactured on the same qualified process and meets all stress-test requirements-including temperature cycling, HTOL, and ESD-per AEC-Q100 Rev G. Full qualification documentation is available upon request for automotive program validation.

What package type does NLVVHC1G32DFT2G use, and what are its key mechanical dimensions?

NLVVHC1G32DFT2G uses the SC-88A (also known as SOT-353) package: a 5-pin, surface-mount, leadless plastic package measuring 1.25 mm × 2.1 mm with 0.65 mm pin pitch. Its height is 0.95 mm max. This ultra-compact outline is optimized for high-density PCB layouts and matches JEDEC MO-178 standards. Pin 1 marking is a dot or beveled edge, and the package is Pb-free, halogen-free, and RoHS compliant per onsemi's environmental policy.
