Product details
Overview
SN74LVC1G17YEAR from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for consumer audio and display interfaces.
For engineers reviewing the SN74LVC1G17YEAR datasheet, SN74LVC1G17YEAR pinout, SN74LVC1G17YEAR application, or SN74LVC1G17YEAR equivalent, this page provides verified package mapping (X2SON-5, 0.8mm × 0.8mm), Schmitt threshold values (VT+ = 2.19V / VT– = 1.51V at 4.5V), Ioff-enabled partial-power-down support, and confirmed alternatives for 5V-tolerant buffer replacement.
Technical Context
The SN74LVC1G17YEAR implements a non-inverting Schmitt-trigger buffer (Y = A) with hysteresis ΔVT = 0.58V at 4.5V, enabling robust noise rejection on slow-rising or noisy digital signals. Its CMOS design maintains low ICC ≤ 10μA while supporting rail-to-rail output swing and 5.5V input overvoltage tolerance independent of VCC.
It features Ioff circuitry that disables outputs and blocks current backflow when VCC = 0V, making it suitable for live insertion and hot-swap applications. Thermal resistance RθJA = 130°C/W (DPW package) enables reliable operation up to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and down-translation from 5V logic to lower-core supplies. |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V buses without level-shifting, even when VCC = 1.8V. |
| tpd (Max) | 4.6ns at 3.3V, CL = 15pF - enables reliable operation in high-speed digital paths up to ~100MHz. |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple LVC loads or moderate capacitive loads (e.g., 16pF traces). |
| Hysteresis (ΔVT) | 0.58V at 4.5V - provides ≥200mV noise margin against EMI/ground bounce in consumer audio/video signal chains. |
| Ioff Current | ±10μA max - ensures safe isolation during partial power-down, preventing back-drive damage in modular systems. |
| ESD Rating | ±2000V HBM - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
SN74LVC1G17YEAR is packaged in the ultra-small X2SON-5 (DPW) package: 0.8mm × 0.8mm body, 0.5mm pitch, no exposed pad. Pin 1 = A (input), Pin 2 = GND, Pin 3 = Y (output), Pin 4 = VCC, Pin 5 = NC (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Input | Schmitt-triggered digital input accepting 0–5.5V; requires external bias if unused to avoid floating state. |
| 2 (GND) | Ground | Reference return path for all internal logic and output drivers; must be low-impedance for stable hysteresis. |
| 3 (Y) | Output | Non-inverting buffered output with rail-to-rail swing and ±24mA drive capability at 3.3V. |
| 4 (VCC) | Power | Supply input (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to this pin. |
| 5 (NC) | No Connect | Internally unconnected; must remain unpopulated and unconnected on PCB to prevent parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.58V hysteresis at 4.5V to reject noise on slow edges - critical for front-panel buttons or sensor signal conditioning. |
| 5.5V-tolerant inputs | Enables direct interface with legacy 5V microcontrollers or USB PHYs without external level shifters. |
| Ioff partial-power-down | Blocks current flow when VCC = 0V, allowing safe hot-plug operation in SSD modules or docking stations. |
| Ultra-small DPW package | 0.64mm² footprint saves >60% board area vs. SOT-23 - ideal for space-constrained portable audio docks and tablets. |
| Low ICC (≤10μA) | Minimizes quiescent power in always-on subsystems like TV standby controllers or wireless headset status indicators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Same silicon, SOT-23-5 package (2.9mm × 1.6mm body); RθJA = 357°C/W vs. 130°C/W for DPW. | Preferred where manual rework or test probing is required; less suitable for ultra-dense portable layouts. | Select SN74LVC1G17DBVR only when board space permits larger footprint and thermal budget allows higher junction rise. |
| 74LVC1G17GW,125 | Nexperia variant in SC-70-5 (2.0mm × 1.25mm); identical electrical specs but different marking and MSL rating (Level-1 vs. TI's Level-1-260C-UNLIM). | Valid for cost-sensitive industrial designs where second-source qualification is mandated. | Choose 74LVC1G17GW,125 when dual-sourcing is required and SC-70 mechanical compatibility is verified in assembly. |
