Product details
Overview
SN74LVC2G17DSF2 from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65 V to 5.5 V operation, performing Y = A logic with hysteresis-enhanced noise immunity. It features ±24-mA output drive at 3.3 V, 5.4 ns max propagation delay at 3.3 V, and Ioff support for live insertion and partial-power-down applications. It is used in audio docks, SSDs, and portable consumer electronics for signal conditioning of noisy or slow-rising inputs.
For engineers reviewing the SN74LVC2G17DSF2 datasheet, SN74LVC2G17DSF2 pinout, SN74LVC2G17DSF2 application, or SN74LVC2G17DSF2 equivalent, key selection criteria include its 6-pin SON (DSF) package, Schmitt-trigger input thresholds (VT+ = 2.0 V, VT– = 1.3 V at 3 V), 5.5-V tolerant inputs, Ioff-enabled back-drive protection, and compatibility with 1.8 V/2.5 V/3.3 V/5 V logic domains.
Technical Context
The SN74LVC2G17DSF2 implements two independent noninverting buffers with Schmitt-trigger inputs, enabling robust signal restoration in noisy environments. Its hysteresis (ΔVT = 0.4–1.1 V depending on VCC) provides distinct VT+ and VT– thresholds to suppress chatter on slow or degraded waveforms.
It supports voltage-level translation across 1.65–5.5 V supply rails and tolerates input voltages up to 5.5 V regardless of VCC. The Ioff circuitry actively disables outputs when VCC = 0 V, blocking current backflow and enabling hot-plug capability in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Max tpd | 5.4 ns at 3.3 V - ensures timing-critical signal buffering with minimal latency in high-speed digital interfaces |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive multiple CMOS loads or moderate capacitive traces without external buffers |
| Input Hysteresis | 0.4 V to 1.4 V (VCC-dependent) - rejects noise spikes and stabilizes switching on slow-rising signals like power-on reset lines |
| Ioff Current | ±10 μA max - prevents damaging back-current during partial power-down, supporting live insertion in modular systems |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V sources even when powered from 1.8 V or 2.5 V rails |
| ESD Rating | 2000 V HBM - meets industrial-grade ESD robustness requirements without external protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVR | SOT-23-6 package (2.90 mm × 1.60 mm); higher thermal resistance (RθJA = 165°C/W vs. DSF's 300°C/W) | Better suited for manual assembly or prototyping due to larger pad pitch; less optimal for ultra-dense layouts | Select when board rework or hand-soldering is required; avoid if footprint area < 1.5 mm² is mandatory |
| SN74LVC2G17DCKR | SC70-6 package (2.00 mm × 1.25 mm); intermediate size between SOT-23 and SON; RθJA = 259°C/W | Offers better thermal performance than DSF but larger than DSF; compatible with standard SC70 pick-and-place tooling | Choose for production scalability with tighter thermal constraints than DSF but smaller than SOT-23 |
Compared with SN74LVC2G17DBVR and SN74LVC2G17DCKR, the SN74LVC2G17DSF2 delivers the smallest footprint (1.0 mm × 1.0 mm) and highest board-area efficiency, making it optimal for wearables and ultra-thin consumer devices-though its higher thermal resistance requires careful local copper pour planning.

FAQ
What is the operating voltage range for the SN74LVC2G17DSF2?
The SN74LVC2G17DSF2 operates from 1.65 V to 5.5 V, supporting interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. This wide VCC range allows the SN74LVC2G17DSF2 to serve as a universal buffer in mixed-supply systems without level-shifting circuitry, and its inputs tolerate up to 5.5 V regardless of applied VCC.
Does the SN74LVC2G17DSF2 support hot-swap or partial-power-down operation?
Yes, the SN74LVC2G17DSF2 includes Ioff circuitry that disables outputs and limits leakage current to ±10 μA when VCC = 0 V. This feature prevents damaging back-current flow during live insertion or system power sequencing, making the SN74LVC2G17DSF2 suitable for modular backplanes and hot-pluggable peripheral designs.
What are the input threshold voltages for the SN74LVC2G17DSF2 at 3.3 V supply?
At VCC = 3.3 V, the SN74LVC2G17DSF2 exhibits VT+ = 2.0 V (positive-going threshold) and VT– = 1.3 V (negative-going threshold), yielding 0.7 V hysteresis. These values ensure reliable noise rejection on slow-rising signals such as power-on reset lines or mechanical switch inputs, and are confirmed in the device's Electrical Characteristics table.
What package type does the SN74LVC2G17DSF2 use, and what are its dimensions?
The SN74LVC2G17DSF2 uses a 6-pin SON (DSF) package measuring 1.0 mm × 1.0 mm with 0.5-mm pitch. This NanoFree™ die-as-package construction eliminates bond wires and reduces footprint by over 50% compared to SOT-23, enabling ultra-compact placement in wearables and thin client devices.
How does the SN74LVC2G17DSF2 differ from standard non-Schmitt buffers like the SN74LVC2G07?
Unlike standard buffers such as the SN74LVC2G07, the SN74LVC2G17DSF2 incorporates Schmitt-trigger inputs with defined VT+ and VT– thresholds and hysteresis. This enables the SN74LVC2G17DSF2 to cleanly restore logic levels from slow, noisy, or degraded waveforms-critical for switch debouncing, power sequencing, and sensor interface applications where standard buffers would oscillate or misfire.
