Product details
Overview
SN74LVC2G17DRYR from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65 V to 5.5 V operation, featuring two independent noninverting buffers with hysteresis (VT+ = 2.0 V, VT– = 1.3 V at 3 V), 5.4 ns max propagation delay at 3.3 V, ±24 mA output drive, and Ioff support for live insertion and partial-power-down systems. It serves signal conditioning and noise-immune level translation in portable audio and power management interfaces.
For engineers reviewing the SN74LVC2G17DRYR datasheet, SN74LVC2G17DRYR pinout, SN74LVC2G17DRYR application, or SN74LVC2G17DRYR equivalent, key selection criteria include Schmitt-trigger input thresholds, 6-pin SON (DRY) package compatibility, Ioff-enabled back-drive protection, and 1.65–5.5 V supply flexibility across mixed-voltage digital subsystems.
Technical Context
The SN74LVC2G17DRYR implements two independent noninverting Schmitt-trigger buffers performing Y = A logic, with separate VT+ and VT– thresholds enabling robust noise rejection on slow or noisy inputs. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking current backflow during hot-swap or partial-power-down events.
Input tolerance up to 5.5 V allows interfacing with higher-voltage logic domains (e.g., 5 V → 3.3 V or 1.8 V translation), while NanoFree™ SON (DRY) packaging uses the silicon die as the package body-1.45 mm × 1.00 mm footprint with wettable flanks for automated optical inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports mixed-supply systems and voltage translation without level shifters |
| tpd (max) | 5.4 ns at 3.3 V - enables timing-critical signal conditioning in high-speed digital control paths |
| VT+ / VT– | 2.0 V / 1.3 V at 3 V - provides 700 mV hysteresis for reliable switching on noisy or slowly rising signals |
| Ioff Current | ±10 μA max - prevents damaging back-current during power sequencing or live insertion |
| Output Drive | ±24 mA at 3.3 V - drives moderate capacitive loads (e.g., PCB traces, multiple gate inputs) without external buffers |

Pinout & Package
SN74LVC2G17DRYR is housed in a 6-pin SON (DRY) package measuring 1.45 mm × 1.00 mm with wettable flanks, optimized for space-constrained portable designs and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Noninverting Schmitt-trigger input for first buffer channel; accepts up to 5.5 V regardless of VCC |
| GND | Ground | Reference return path for logic and power; must be low-impedance for stable hysteresis performance |
| 2A | Input 2 | Noninverting Schmitt-trigger input for second buffer channel; electrically isolated from 1A |
| 1Y | Output 1 | Buffered, noise-immune replica of 1A; supports rail-to-rail swing and Ioff disable when VCC = 0 |
| VCC | Power Pin | Single supply input (1.65–5.5 V); powers both buffers and enables Ioff logic state retention |
| 2Y | Output 2 | Buffered, noise-immune replica of 2A; independently driven with same specs as 1Y |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 700 mV hysteresis at 3 V ensures clean edge generation from slow or noisy signals (e.g., mechanical switch bounce, analog sensor outputs) |
| Ioff support | Enables safe live insertion and partial-power-down by disabling outputs and blocking back-current when VCC = 0 V |
| 5.5 V tolerant inputs | Allows direct connection to 5 V logic without external resistors or translators-simplifies mixed-voltage board design |
| NanoFree™ SON (DRY) | 1.45 mm × 1.00 mm footprint reduces PCB area by >50% vs. SOT-23; wettable flanks enable AOI-compatible reflow |
| Low ICC | 10 μA max quiescent current extends battery life in always-on monitoring circuits (e.g., power button detection) |

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); identical electrical specs and pinout but larger footprint and no wettable flanks | Better suited for prototyping or manual rework; less optimal for high-density automated assembly | Select when board layout prioritizes hand-soldering or legacy footprint compatibility over miniaturization |

FAQ
What is the function of SN74LVC2G17DRYR?
SN74LVC2G17DRYR is a dual noninverting Schmitt-trigger buffer performing Y = A logic on two independent channels. Each channel provides hysteresis (VT+ and VT– thresholds), 5.5 V input tolerance, and Ioff-enabled partial-power-down operation-making it ideal for cleaning noisy digital signals in portable and industrial systems.
Does SN74LVC2G17DRYR support 5 V input signals while operating at 3.3 V VCC?
Yes. SN74LVC2G17DRYR features 5.5 V tolerant inputs, allowing direct connection of 5 V logic signals even when powered at 1.65–3.3 V. This eliminates external level-shifting components and simplifies mixed-voltage interface design in systems like USB-C docks or legacy peripheral adapters.
What is the significance of Ioff in SN74LVC2G17DRYR?
Ioff in SN74LVC2G17DRYR disables output drivers and blocks current flow when VCC = 0 V, preventing back-driving of powered-down sections. This enables safe live insertion, hot-swap capability, and robust power sequencing-essential in SSD modules and modular industrial controllers where subsystems power up/down independently.
Which package type does SN74LVC2G17DRYR use, and why is it notable?
SN74LVC2G17DRYR uses the 6-pin SON (DRY) package-1.45 mm × 1.00 mm with wettable flanks. Its NanoFree™ construction eliminates traditional packaging material, reducing size by >50% vs. SOT-23 and enabling automated optical inspection for high-yield manufacturing in ultra-compact consumer electronics.
Can SN74LVC2G17DRYR replace SN74LVC2G17DBVR in an existing design?
SN74LVC2G17DRYR is not a drop-in replacement for SN74LVC2G17DBVR due to different package dimensions (SON vs. SOT-23) and land pattern. While electrically identical, PCB redesign is required to accommodate the smaller 1.45 mm × 1.00 mm DRY footprint and adjust solder paste stencil parameters for wettable flank reflow.
