Product details

Overview

74LVC2G14FW4-7 from Diodes Incorporated is a dual Schmitt trigger inverter IC in X2-DFN1010-6 (1.0 mm × 1.0 mm) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, 5.5 V-tolerant inputs, and IOFF partial power-down protection. It enables robust signal conditioning in space-constrained mixed-voltage interfaces such as USB-C port detection and I²C bus level shifting.

For engineers reviewing the 74LVC2G14FW4-7 datasheet, 74LVC2G14FW4-7 pinout, 74LVC2G14FW4-7 application, or 74LVC2G14FW4-7 equivalent, key selection criteria include hysteresis width (0.4–1.9 V), propagation delay (≤6.7 ns at 3.3 V), IOFF leakage (<±20 µA), and DFN thermal resistance (θJA = 510 °C/W).

Technical Context

This device implements two independent Schmitt-trigger inverters with push-pull outputs, each featuring asymmetric input thresholds (VT+ = 1.3–3.8 V, VT− = 0.6–2.5 V at VCC = 3–5.5 V) to reject noise on slow-rising or noisy digital signals. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow between powered and unpowered rails.

The logic function Y = A̅ is implemented with rail-to-rail CMOS output swing and guaranteed switching down to 1.65 V. Input tolerance to 5.5 V allows direct interfacing with legacy 5 V logic while powered from 1.8 V or 3.3 V supplies-critical for voltage translation in portable system power domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains
Input Voltage Tolerance	Up to 5.5 V - enables safe interfacing with higher-voltage signals without external clamping
Hysteresis Width (∆VT)	0.40 V to 1.90 V - rejects up to ~1.9 V of input noise without false triggering
Max Propagation Delay	6.7 ns at VCC = 3.3 V, TA = −40°C to +125°C - ensures timing compliance in high-speed control loops
Output Drive Strength	±24 mA at VCC = 3.0 V - drives 50 Ω transmission lines or multiple 74LVC inputs directly
IOFF Leakage Current	±20 µA max at 5.5 V - prevents >20 µA backfeed current during partial power-down
ESD Robustness	2000 V HBM, 1000 V CDM - meets industrial-grade ESD immunity requirements

Pinout & Package

X2-DFN1010-6 package: 1.0 mm × 1.0 mm × 0.4 mm body, 0.35 mm pad pitch, NiPdAu terminal finish, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1	1A	First inverter input - accepts 5.5 V-tolerant logic signal; triggers on rising/falling edges per Schmitt thresholds
2	GND	Digital ground reference - must be low-impedance connection to minimize noise coupling into threshold comparators
3	2A	Second inverter input - electrically isolated from 1A; enables dual independent signal conditioning paths
4	2Y	Second inverter output - push-pull CMOS output with rail-to-rail swing and ±24 mA drive capability
5	VCC	Power supply - supplies both inverters; IOFF circuit activates when VCC = 0 V to disable outputs
6	1Y	First inverter output - identical electrical characteristics to 2Y; shares same VCC and GND connections

Key Features

Feature	Design Value
Dual Schmitt-trigger inversion	Two independent hysteresis-based inverters reject noise on slow or noisy signals without external RC components
IOFF partial power-down	Outputs enter high-impedance state when VCC = 0 V, blocking current flow between live and unpowered subsystems
5.5 V-tolerant inputs	Accepts 5 V logic levels while operating from 1.65–3.3 V supplies - eliminates need for discrete level shifters
Ultra-small X2-DFN1010-6	1.0 mm × 1.0 mm footprint - saves >70% board area vs. SOT26, enabling dense portable PCB layouts
Low ICC quiescent current	≤40 µA at 5.5 V - minimizes standby power in battery-powered IoT sensor nodes and wearables

Applications

USB-C Port Detection

I²C Bus Level Shifting

Use Scenario: Detecting CC line voltage polarity and presence in USB-C receptacles to determine plug orientation and source/sink role.

IC Role / Device Role / Timing Role: Dual Schmitt inverter conditions noisy, slow-rising CC analog voltages into clean digital logic levels for MCU GPIO sampling.

Use Value: Eliminates external RC filters and reduces BOM count by integrating hysteresis and noise immunity in one 1.0 mm² package.

Use Scenario: Translating I²C signals between 1.8 V microcontroller and 3.3 V sensor while maintaining bus integrity and rise-time compliance.

IC Role / Device Role / Timing Role: Inverting SDA/SCL with 5.5 V-tolerant inputs allows 3.3 V pull-ups to coexist with 1.8 V driver outputs without damage.

Use Value: Enables bidirectional level translation using only two inverters per bus line, avoiding dedicated translator ICs or MOSFET solutions.

Power Sequencing Control

Reset Signal Conditioning

Use Scenario: Generating synchronized enable/disable signals for multiple voltage rails during system power-up/down sequences.

IC Role / Device Role / Timing Role: Inverts delayed power-good signals to generate active-low enable pulses with noise margin against supply ripple.

Use Value: Schmitt hysteresis prevents chatter on marginal PG signals, ensuring glitch-free sequencing even under load transients.

Use Scenario: Debouncing and cleaning mechanical reset button inputs before feeding to microcontroller reset pin.

IC Role / Device Role / Timing Role: Converts slow, bouncing switch transitions into monotonic, fast-rising reset pulses with defined timing margins.

Use Value: Replaces RC + buffer designs with a single IC that guarantees minimum pulse width and eliminates capacitor aging drift.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schmitt inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G14DCKR	SOT23-6 package (2.8 mm × 2.2 mm); higher θJA (204 °C/W); same electrical specs	Less suitable for ultra-dense layouts; better thermal performance in low-airflow environments	Select when board space permits larger package and thermal management prioritizes junction-to-ambient conduction over footprint
74LVC2G14FW5-7	X1-DFN1010-6 (Type B) - identical footprint but different internal die attach and marking; same pinout and specs	No functional difference; alternate manufacturing lot or revision path for supply continuity	Select when FW4-7 stock is constrained; fully interchangeable in design and layout

Compared with SN74LVC2G14DCKR, the 74LVC2G14FW4-7 reduces PCB area by 75% and improves high-frequency noise rejection via tighter DFN parasitics, while FW5-7 offers identical form-fit-function with alternate traceability-making FW4-7 optimal for miniaturized consumer electronics where size and EMI resilience are critical.

FAQ

What is the maximum operating temperature for 74LVC2G14FW4-7?

The device is rated for continuous operation from −40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C, and thermal design must account for its θJA of 510 °C/W in the X2-DFN1010-6 package-requiring careful copper pour and via placement under the exposed pad for reliable high-temperature use.

Can 74LVC2G14FW4-7 be used as a non-inverting Schmitt buffer?

No-it is a fixed inverting gate (Y = A̅). To implement non-inverting Schmitt buffering, two cascaded 74LVC2G14FW4-7 devices are required (inverter + inverter = buffer), preserving hysteresis and noise immunity. The device does not support reconfiguration or mode selection.

Does the IOFF feature require external biasing or control signals?

No. IOFF activates automatically when VCC is removed or falls below ~0.8 V; no external enable/disable pin or configuration is needed. The outputs transition to high-impedance state passively, blocking current flow regardless of input voltage-simplifying power-domain isolation in multi-rail systems.

Is the X2-DFN1010-6 package compatible with standard reflow profiles?

Yes. It is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020 and qualified for standard lead-free reflow profiles (peak ≤260°C). The NiPdAu terminal finish ensures solderability; recommended pad layout (0.35 mm pitch, 0.2 mm × 0.55 mm pads) is published by Diodes to prevent tombstoning and voiding.
