Product details

Overview

NLVVHC1G02DFT1G from onsemi is a single 2-input NOR gate logic IC designed for high-speed, low-voltage operation in space-constrained applications. It operates across 2.0 V to 5.5 V supply, delivers 3.5 ns typical propagation delay at 5 V, features CMOS-level input thresholds, and supports 5.5 V over-voltage tolerant I/O - enabling robust 3 V/5 V mixed-supply interfacing in portable power management circuits.

For engineers reviewing the NLVVHC1G02DFT1G datasheet, pinout, applications, or equivalent options, key selection criteria include its SC-88A (SOT-353) 5-pin package, IOFF partial power-down capability, ±8 mA drive strength at 3.0 V, AEC-Q100 qualification for automotive use, and compatibility with 15 pF/50 pF load conditions per AC specs.

Technical Context

The NLVVHC1G02DFT1G implements a standard two-input NOR Boolean function (Y = NOT(A OR B)) using advanced CMOS process technology. Its input structure tolerates up to 5.5 V regardless of VCC, allowing safe level-shifting between 3 V and 5 V domains without external components.

It supports partial power-down via IOFF functionality, which disables I/O leakage when VCC = 0 V - critical for hot-swap and battery-backup systems. The device exhibits rail-to-rail output swing and maintains specified VOH/VOL across −55 °C to +125 °C operating temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - enables direct integration into both 3.3 V and 5 V logic subsystems without level translators.
tPD (Typ)	3.5 ns at VCC = 5 V, CL = 15 pF - supports >100 MHz toggle rates in timing-critical control paths.
IOH/IOL	±8 mA at VCC = 3.0 V - drives multiple 74LVC inputs or small LEDs directly without buffering.
Input Voltage Tolerance	−0.5 V to +5.5 V - prevents latch-up or damage during supply sequencing or transient overvoltage events.
IOFF Leakage	≤10 µA at VCC = 0 V - ensures signal integrity and prevents back-powering in powered-down system sections.
Operating Temp	−55 °C to +125 °C - qualified for under-hood automotive, industrial motor control, and outdoor embedded systems.
ESD Rating	HBM: 2000 V - meets IEC 61000-4-2 Level 2 for board-level ESD robustness in consumer and industrial environments.

Pinout & Package

Package: SC-88A (SOT-353), 5-pin surface-mount, 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm pitch, Pb-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
1	Input B	Second logic input; accepts CMOS-level signals; tolerant to 5.5 V regardless of VCC.
2	Input A	Primary logic input; identical electrical behavior to Pin 1; enables standard NOR truth table implementation.
3	GND	Ground reference for all internal circuitry and I/O; must be connected before applying VCC or inputs.
4	Output Y	Inverted OR result (Y = NOT(A OR B)); rail-to-rail swing; capable of sourcing/sinking ±8 mA at 3.0 V.
5	VCC	Positive supply; powers internal logic and output stage; supports wide 2.0–5.5 V range with stable DC characteristics.

Key Features

Feature	Design Value
Over-Voltage Tolerant I/O	Inputs and outputs withstand up to 5.5 V independent of VCC - eliminates need for external clamping diodes in mixed-voltage designs.
IOFF Partial Power-Down	Input/output leakage ≤10 µA when VCC = 0 V - prevents unintended current paths during system sleep or hot-insertion scenarios.
High-Speed Performance	3.5 ns typical propagation delay at 5 V with 15 pF load - suitable for clock gating, enable control, and fast state-machine feedback loops.
AEC-Q100 Qualified	Qualified to Grade 1 (−40 °C to +125 °C) and Grade 3 (−40 °C to +125 °C) per datasheet revision history - approved for automotive infotainment and body electronics.
Low Input Capacitance	CIN = 4.0 pF (typ) - minimizes loading on preceding drivers and preserves signal edge integrity in high-frequency routing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC74VHC1GT02DFT1G	TTL-level input thresholds (VIH = 1.4 V @ 3 V); otherwise identical AC/DC specs and package.	Better suited for legacy 5 V TTL interface legacy systems where input noise margin favors lower VIH.	Select when interfacing with older microcontrollers or ASICs with TTL-compatible outputs.
SN74LVC1G02DBVR	Wider VCC range (1.65–5.5 V); slightly higher tPD (4.5 ns typ @ 3.3 V); same SC-70 package footprint.	Preferred for ultra-low-voltage battery-powered devices requiring 1.8 V operation not supported by NLVVHC1G02DFT1G.	Choose when design requires operation below 2.0 V or tighter parametric control per JEDEC JESD8-12E.

Compared with MC74VHC1GT02DFT1G, NLVVHC1G02DFT1G offers superior noise immunity in CMOS-dominated systems; versus SN74LVC1G02DBVR, it provides faster propagation and stronger drive at 5 V but lacks sub-2.0 V support - making it optimal for cost-sensitive 3.3 V/5 V industrial controls.

FAQ

What is the maximum operating temperature range for NLVVHC1G02DFT1G?

The NLVVHC1G02DFT1G is rated for operation from −55 °C to +125 °C. This extended temperature range is validated per the datasheet's Recommended Operating Conditions table and supports deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment where thermal cycling exceeds commercial-grade limits. The NLVVHC1G02DFT1G maintains full DC and AC specifications across this full range.

Does NLVVHC1G02DFT1G support partial power-down functionality?

Yes, NLVVHC1G02DFT1G supports IOFF partial power-down protection. When VCC = 0 V, input and output leakage remains ≤10 µA, preventing back-driving or unintended current flow from live signal lines into a powered-down subsystem. This feature is explicitly characterized in the DC Electrical Characteristics table and is essential for hot-swap and battery-backed applications.

Can NLVVHC1G02DFT1G safely interface 5 V signals to a 3.3 V microcontroller?

Yes, NLVVHC1G02DFT1G can safely interface 5 V signals to a 3.3 V microcontroller. Its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail - delivering a clean 3.3 V HIGH and near-0 V LOW when powered at 3.3 V. No external level-shifting components are required, reducing BOM count and PCB area.

Is NLVVHC1G02DFT1G pin-compatible with other 5-pin SOT-353 logic gates?

No, NLVVHC1G02DFT1G is not universally pin-compatible with all 5-pin SOT-353 logic gates. Its pinout (Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC) is specific to the VHC1G series. Devices like SN74LVC1G02DBVR share the same SC-70 package outline but differ in pin assignment - always verify against the exact datasheet pin diagram before layout reuse.

What packaging and marking information applies to NLVVHC1G02DFT1G?

NLVVHC1G02DFT1G uses the SC-88A (SOT-353) package per Case 419A, marked with "V3" as the specific device code and "Q2" indicating tape-and-reel orientation. The "G" suffix confirms Pb-free and RoHS compliance. Marking appears on the top surface per generic SC-88A diagrams, with date code following the "V3" identifier - consistent with onsemi's standard SC-88A marking convention.
