Product details
Overview
SN74LVC1G14DRY2 from Texas Instruments is a single Schmitt-trigger inverter IC designed for 1.65V to 5.5V operation, performing Y = A logic inversion with hysteresis (ΔVT = 0.37–1.11V), 4.6ns max propagation delay at 3.3V, ±24mA output drive, and Ioff-enabled partial-power-down protection. It serves as a noise-immune signal conditioner in push-button debounce, level translation, and clock conditioning circuits.
For engineers reviewing the SN74LVC1G14DRY2 datasheet, SN74LVC1G14DRY2 pinout, SN74LVC1G14DRY2 application, or SN74LVC1G14DRY2 equivalent, this page delivers verified electrical parameters, USON-6 package layout details, Schmitt-trigger threshold behavior, thermal metrics, and real-world implementation guidance for industrial, audio, and embedded timing interfaces.
Technical Context
The SN74LVC1G14DRY2 implements a single CMOS inverter with Schmitt-trigger inputs-featuring distinct VT+ (0.79–3.33V) and VT– (0.39–2.29V) thresholds-to reject slow-rising or noisy signals. Its balanced push-pull output stage supports ±24mA drive at 3.3V while maintaining low ICC (≤10µA) and enabling robust Ioff isolation during power-down.
Designed for wide VCC range (1.65–5.5V), it accepts overvoltage-tolerant inputs up to 5.5V independent of supply, operates across –40°C to 85°C (DRY package), and integrates NanoFree™ USON-6 packaging-using the die itself as the package body-for minimal footprint (1.45mm × 1.00mm) and enhanced thermal performance (RθJA = 369.6°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| tpd (max) | 4.6ns at 3.3V, CL = 15pF - ensures fast edge generation for debounced switch outputs and clock shaping. |
| VT+ / VT– | 1.50V / 0.84V (at 3V VCC) - provides 0.66V hysteresis to suppress contact bounce and EMI-induced false triggers. |
| Ioff Leakage | ±10µA max - prevents backflow current when VCC = 0V, protecting downstream circuitry in hot-swap or partial-power-down systems. |
| Output Drive | ±24mA at 3.3V - drives moderate capacitive loads (e.g., PCB traces, multiple gate inputs) without external buffers. |
| ESD Rating | 2000V HBM - meets industrial handling requirements and reduces need for external protection diodes. |
| Package | USON-6 (DRY) - 1.45mm × 1.00mm body, 0.5mm pitch, no leads, suitable for high-density portable PCBs. |
Pinout & Package
SN74LVC1G14DRY2 uses the Texas Instruments DRY package: 6-pin ultra-thin small-outline no-lead (USON) with 0.5mm pitch, 1.45mm × 1.00mm body, and wettable flank terminals for automated optical inspection (AOI). Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No internal connection (N.C.) | Internally unconnected; may be left floating or tied to GND/VCC per board routing needs - no functional impact. |
| 2 | Input (A) | Schmitt-trigger input accepting 0–5.5V; immune to slow edges and noise due to hysteresis. |
| 3 | GND | Ground reference for all internal logic and output stages; must be low-impedance for stable noise margin. |
| 4 | VCC | Positive supply (1.65–5.5V); requires local 0.1µF bypass capacitor placed adjacent to pin for transient suppression. |
| 5 | N.C. | No internal connection; same status as Pin 1 - electrically inert, soldered for mechanical stability only. |
| 6 | Output (Y) | Inverted, buffered output with ±24mA drive; compatible with LVC-family logic levels and open-drain pull-up configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input hysteresis | ΔVT = 0.37–1.11V across VCC range - eliminates multiple triggering from mechanical switch bounce or EMI-coupled transients. |
| Ioff partial-power-down protection | Outputs enter high-Z state with ≤±10µA leakage when VCC = 0V - prevents backdrive damage in multi-rail systems. |
| NanoFree™ USON-6 packaging | 1.45mm × 1.00mm footprint, no leads, die-as-package construction - maximizes PCB area efficiency and thermal dissipation. |
| Overvoltage-tolerant inputs | Accepts VI up to 5.5V regardless of VCC setting - simplifies interfacing with mixed-voltage sensors or legacy peripherals. |
| Low dynamic power | ICC ≤ 10µA (max) at static conditions - extends battery life in always-on portable audio and IoT endpoint applications. |
Applications
| Push-Button Debounce | Level Translation Interface |
|---|---|
|
Use Scenario: Mechanical push buttons in consumer remotes or industrial HMI panels generate contact bounce lasting 5–20ms, causing unintended multiple interrupts. IC Role / Device Role / Timing Role: SN74LVC1G14DRY2 acts as a hardware debounce filter by converting noisy, slow-rising button signals into clean, single-edge logic transitions via hysteresis. Use Value: Eliminates need for software debouncing or RC + microcontroller GPIO polling, reducing firmware complexity and CPU load in resource-constrained devices. |
Use Scenario: Interfacing a 5V sensor output to a 3.3V microcontroller GPIO that lacks 5V-tolerant inputs. IC Role / Device Role / Timing Role: SN74LVC1G14DRY2 functions as a unidirectional level translator: 5V input accepted safely, 3.3V-compatible output driven. Use Value: Enables direct connection without external resistors or dedicated level-shifter ICs, saving BOM cost and board space in compact SSD or tablet designs. |
| Audio System Clock Conditioning | Power Supply Sequencing Monitor |
|
Use Scenario: Cleaning up jittery or undershoot-prone clock signals from crystal oscillators or PLLs feeding audio DACs in portable speakers. IC Role / Device Role / Timing Role: SN74LVC1G14DRY2 serves as a waveform shaper - squaring up distorted edges and suppressing sub-threshold noise on clock lines. Use Value: Reduces jitter-induced audio artifacts (e.g., hiss, distortion) by ensuring monotonic, rail-to-rail clock transitions to sensitive analog subsystems. |
Use Scenario: Monitoring delayed enable signals in telecom AC/DC power supplies where sequencing faults must trigger immediate shutdown. IC Role / Device Role / Timing Role: SN74LVC1G14DRY2 converts slowly ramping voltage rails (e.g., 12V standby → 3.3V main) into sharp logic-level assertions for supervisor ICs. Use Value: Provides deterministic, noise-immune assertion of power-good signals - critical for preventing latch-up or brownout in multi-rail server PSUs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | SOT-23-5 package (2.90mm × 2.80mm), higher RθJA (357.1°C/W), rated for –40°C to 125°C. | Better thermal margin in high-ambient environments; larger footprint limits use in ultra-compact portable designs. | Choose DBVR for industrial temperature range and manual assembly compatibility; DRY2 preferred for space-constrained, consumer-grade layouts. |
| 74LVC1G14GW,125 | NXP SC-70-5 package (2.00mm × 2.10mm), identical electrical specs, JEDEC-compliant marking, RoHS/REACH certified. | Same functional behavior but different pinout (A/GND/Y/VCC/N.C. vs. DRY's A/GND/VCC/N.C./Y) - requires PCB redesign. | Select GW,125 only if dual-sourcing from NXP is required; verify pin mapping and thermal derating before substitution. |
Compared with SN74LVC1G14DBVR and 74LVC1G14GW,125, the SN74LVC1G14DRY2 offers the smallest footprint and lowest profile among LVC-family Schmitt inverters, making it optimal for space-limited portable audio and SSD applications - though its 85°C max ambient rating requires thermal validation in high-power enclosures.

FAQ
What is the maximum operating temperature for SN74LVC1G14DRY2?
The SN74LVC1G14DRY2 is specified for operation from –40°C to +85°C ambient temperature. This limit is defined by its USON-6 (DRY) package construction and thermal characteristics (RθJA = 369.6°C/W). Exceeding 85°C ambient may cause parameter drift or reliability degradation; derating is required above this point per TI's thermal guidelines.
Does SN74LVC1G14DRY2 support 5V logic inputs while powered from 3.3V?
Yes. The SN74LVC1G14DRY2 features overvoltage-tolerant inputs rated up to 5.5V regardless of VCC level. When powered from 3.3V, it safely accepts 5V signals on pin A - eliminating external level-shifting components in mixed-voltage systems such as USB-C audio docks or SSD controllers interfacing with legacy peripherals.
How does the Schmitt-trigger hysteresis in SN74LVC1G14DRY2 improve noise immunity?
The SN74LVC1G14DRY2 uses separate VT+ (positive-going threshold) and VT– (negative-going threshold) values - e.g., 1.50V and 0.84V at 3V VCC - creating 0.66V hysteresis. This prevents oscillation on slow or noisy edges by requiring a >0.66V signal swing to toggle state, effectively rejecting sub-threshold interference common in mechanical switches or long PCB traces.
Can SN74LVC1G14DRY2 be used in partial-power-down systems?
Yes. The SN74LVC1G14DRY2 incorporates Ioff circuitry that disables outputs and limits leakage to ±10µA when VCC = 0V. This prevents back-current flow into powered-down sections of multi-rail systems - a key requirement in hot-pluggable modules, battery-backed memory subsystems, and modular telecom power supplies.
What is the recommended bypass capacitor for SN74LVC1G14DRY2?
A 0.1µF ceramic capacitor is recommended directly between VCC (pin 4) and GND (pin 3) of the SN74LVC1G14DRY2, placed as close as possible to the pins. For improved high-frequency noise rejection, a parallel 1µF capacitor may be added - both must use short, low-inductance traces to minimize impedance and ensure stable switching performance.
