Product details
Overview
SN74LVC1G17DPWR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in noise-prone or slow-rising digital interfaces. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, achieves 4.6ns max propagation delay, and features 5.5V-tolerant inputs - enabling level translation in mixed-voltage systems such as USB peripheral interfaces and SSD power sequencing.
For engineers reviewing the SN74LVC1G17DPWR datasheet, SN74LVC1G17DPWR pinout, SN74LVC1G17DPWR application, or SN74LVC1G17DPWR equivalent, this page provides verified package mapping (X2SON-5, 0.8mm × 0.8mm), confirmed Schmitt-trigger hysteresis (0.36–1.04V), Ioff-enabled partial-power-down support, ESD ratings per JESD22, and real-world use cases in audio docks and enterprise tablets.
Technical Context
The SN74LVC1G17DPWR implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds: VT+ ranges from 0.76V (1.65V VCC) to 3.33V (5.5V VCC), and VT− from 0.35V to 2.4V, yielding hysteresis (ΔVT) of 0.36V–1.04V. This architecture rejects noise on slow or degraded signals without external components.
Its Ioff circuitry disables outputs when VCC = 0V, preventing back-drive current and supporting live insertion in hot-swap applications. The DPW package uses 0.5mm pitch and 0.64mm² footprint, maintaining compatibility with standard SMT reflow while minimizing board area in space-constrained designs like wireless headsets and SSD modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interfacing between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - enables robust down-translation from higher-voltage peripherals (e.g., legacy 5V sensors) into lower-VCC systems. |
| Max Propagation Delay | 4.6ns at 3.3V, CL = 15pF - ensures reliable timing in high-speed data paths up to ~100MHz clock domains. |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple CMOS loads or moderate capacitive traces without buffering. |
| Ioff Current | ±10μA max - guarantees safe isolation during partial power-down, critical for system-level power sequencing in telecom AC/DC supplies. |
| Hysteresis (ΔVT) | 0.36V–1.04V across VCC range - provides noise immunity against >300mV peak-to-peak interference on input lines. |
| ESD Rating (HBM) | ±2000V - meets industrial-grade handling requirements without additional protection circuitry. |
Pinout & Package
SN74LVC1G17DPWR uses the DPW (X2SON-5) package: 0.8mm × 0.8mm body, 0.5mm pitch, 5-terminal configuration with no exposed pad. Pin 1 is marked by a dot; Pin 3 is GND; Pin 5 is VCC. The package is lead-free, RoHS-compliant, and MSL Level-1 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | 5.5V-tolerant Schmitt-trigger input; accepts slow/noisy signals and drives internal buffer stage. |
| 2 | Output (Y) | CMOS push-pull output with ±24mA drive; replicates input logic state with hysteresis-based noise rejection. |
| 3 | GND | Ground reference for all internal circuitry and output stage; must be low-impedance for stable switching. |
| 4 | No Connect (NC) | Internally unconnected; must remain floating - no external tie required or recommended. |
| 5 | VCC | Power supply input (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small X2SON-5 package | 0.64mm² footprint saves >70% board area vs. SOT-23, enabling miniaturization in portable audio docks and enterprise tablets. |
| Schmitt-trigger input with programmable hysteresis | Hysteresis range (0.36–1.04V) is voltage-scalable with VCC - eliminates need for external RC networks in noisy sensor interfaces. |
| Ioff partial-power-down support | Blocks current flow when VCC = 0V - allows safe insertion into powered-backplane systems like server SSD trays. |
| 5.5V-tolerant inputs on all VCC levels | Enables single-buffer reuse across 1.8V–5V subsystems - reduces BOM count in multi-rail consumer electronics. |
| Low ICC (10μA max) | Minimizes quiescent power in always-on signal conditioning paths, e.g., wake-on-USB detection in wireless keyboards. |
Applications
| Audio Dock Interface | SSD Power Sequencing |
|---|---|
Use Scenario: Signal conditioning between 5V analog audio source and 3.3V codec in portable dock. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising control lines (e.g., mute enable) and translates 5V logic to 3.3V domain. Use Value: Eliminates external pull-ups and RC filters; hysteresis rejects coupling noise from nearby Class-D amplifiers. |
Use Scenario: Enabling 12V-to-3.3V power rail sequencing in client SSD modules.

Use Scenario: Debouncing mechanical switch inputs (volume, play/pause) in Bluetooth headset PCBs. IC Role / Device Role / Timing Role: Single-gate Schmitt buffer converts erratic switch transitions into clean CMOS logic edges. Use Value: Replaces discrete RC + inverter solutions; 0.64mm² DPW package fits within tight 2-layer flex PCB constraints. |
Use Scenario: Isolating and conditioning GPIO signals between application processor and peripheral modules. IC Role / Device Role / Timing Role: Level-translating buffer for 1.8V SoC outputs driving 3.3V display backlight controllers. Use Value: 5.5V input tolerance accommodates margin drift in aging LDOs; ±24mA drive handles 20pF trace + IC input capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | SOT-23-5 package (2.9mm × 1.6mm body); 3000-unit tape-and-reel; identical electrical specs and pinout. | Requires larger PCB area; better suited for prototyping or manual assembly where X2SON reflow is unavailable. | Select when board layout lacks fine-pitch reflow capability or when hand-soldering validation is needed pre-production. |
| 74LVC1G17GW,125 | Nexperia SC-70-5 package (2.0mm × 1.25mm); same VCC range and hysteresis, but max tpd = 5.5ns at 3.3V (vs. 4.6ns). | Marginally slower propagation; slightly higher RθJA (371°C/W vs. 340°C/W for DPW) limits high-density thermal performance. | Choose for second-source assurance in cost-sensitive consumer designs where 0.9ns timing margin is acceptable. |
Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the SN74LVC1G17DPWR offers the smallest footprint and fastest propagation delay, making it optimal for space- and speed-critical embedded applications like wireless headsets and SSD modules - though SOT-23 and SC-70 variants provide broader assembly flexibility.

FAQ
What is the maximum operating temperature for SN74LVC1G17DPWR?
The SN74LVC1G17DPWR is fully specified for operation from –40°C to +125°C ambient temperature. Its thermal resistance (RθJA = 340°C/W) and junction-to-board metric (RθJB = 294°C/W) ensure reliable performance in thermally constrained environments like enclosed SSD modules and tablet edge computing units where airflow is limited.
Does SN74LVC1G17DPWR support 5V logic inputs when powered at 1.8V?
Yes, SN74LVC1G17DPWR supports 5.5V-tolerant inputs across its full 1.65V–5.5V VCC range. When powered at 1.8V, it safely accepts 5V signals on pin 1 (A) without damage or clamping, enabling direct interface with legacy 5V microcontrollers or sensors in mixed-voltage systems.
What is the purpose of the NC pin on SN74LVC1G17DPWR?
Pin 4 of SN74LVC1G17DPWR is a No-Connect (NC) terminal with no internal connection. It must remain unconnected - neither tied to VCC nor GND - to avoid unintended parasitic coupling or package stress. This design simplifies routing in ultra-dense layouts where every trace matters.
How does the Schmitt-trigger function improve noise immunity in SN74LVC1G17DPWR?
The SN74LVC1G17DPWR uses separate positive-going (VT+) and negative-going (VT−) input thresholds, creating hysteresis (ΔVT = 0.36–1.04V). This prevents multiple output transitions when input signals cross the threshold slowly or with noise, making it ideal for debouncing switches or cleaning up signals from long cables in audio docks and wireless peripherals.
Is SN74LVC1G17DPWR compatible with standard reflow profiles?
Yes, SN74LVC1G17DPWR is MSL Level-1 rated with unlimited floor life and qualified for standard lead-free reflow profiles (peak 260°C). Its X2SON-5 package has 0.5mm pitch and coplanar leads, ensuring compatibility with automated SMT lines used for high-volume production of consumer electronics and SSDs.
