Product details
Overview
SN74LVC2G17DCKTE4 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 applications. It is used in audio docks, SSDs, and portable consumer electronics for noise-immune signal conditioning.
For engineers reviewing the SN74LVC2G17DCKTE4 datasheet, SN74LVC2G17DCKTE4 pinout, SN74LVC2G17DCKTE4 application, or SN74LVC2G17DCKTE4 equivalent, key selection criteria include Schmitt-trigger input thresholds, 6-pin SC70 package compatibility, 5.5 V-tolerant inputs, Ioff-enabled back-drive protection, and 125°C operational temperature range.
Technical Context
This device implements two independent noninverting buffer functions (Y = A) with Schmitt-trigger inputs that provide voltage hysteresis-VT+ = 2.0 V and VT– = 1.3 V at VCC = 3 V-enabling robust noise immunity on slow or noisy signals. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing current backflow during hot-swap or power sequencing.
The SN74LVC2G17DCKTE4 supports down-translation (e.g., 5 V → 3.3 V or 1.8 V) and accepts input voltages up to 5.5 V regardless of VCC level. It operates across –40°C to +125°C and delivers 24 mA sink/source drive at 3.3 V while consuming ≤10 μA ICC in static conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across mixed-voltage systems including 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tpd Max | 5.4 ns at VCC = 3.3 V - ensures timing-critical signal buffering in high-speed digital interfaces |
| Input Threshold Hysteresis | ΔVT = 0.7 V at VCC = 3 V - suppresses chatter on slow-rising/falling signals such as mechanical switch inputs or sensor outputs |
| Ioff Current | ±10 μA at VCC = 0 V - blocks damaging back-current during live insertion or partial power-down sequences |
| Output Drive | ±24 mA at VCC = 3.3 V - drives moderate capacitive loads (e.g., PCB traces, multiple gate inputs) without external buffers |
| ESD Rating | 2000 V HBM - meets industrial-level electrostatic discharge immunity requirements per JESD22-A114 |
| Operating Temp | –40°C to +125°C - qualified for extended-temperature automotive and industrial environments |
Pinout & Package

| 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 both 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 noninverting output corresponding to 1A; supports rail-to-rail swing and Ioff disable |
| VCC | Power Supply | Core supply pin (1.65–5.5 V); requires local 0.1 μF bypass capacitor placed adjacent to pin |
| 2Y | Output 2 | Buffered noninverting output corresponding to 2A; independently driven and Ioff-controlled |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.7 V hysteresis at 3 V to reject noise on slow edges-critical for pushbutton debouncing and analog sensor interfacing |
| Ioff support | Enables safe hot-plug operation by disabling outputs and blocking back-current when VCC = 0 V |
| 5.5 V-tolerant inputs | Allows direct connection to 5 V signals while powered from 1.8 V or 3.3 V-eliminates level-shifter components |
| NanoFree™ packaging | SC70-6 footprint uses die-as-package construction for minimal board area (2.5 mm²) and reduced thermal resistance |
| Low ICC | ≤10 μA quiescent current enables use in battery-powered devices with multi-year standby life |

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 |
|---|---|---|---|
| SN74LVC2G17DBVT | SOT-23-6 package (2.90 mm × 1.60 mm); 165°C/W RθJA vs. 259°C/W for DCK; identical electrical specs | Larger footprint but higher thermal mass; preferred for manual rework or high-reliability thermal cycling | Select DBVT when board layout allows larger package and thermal derating margin is prioritized over miniaturization |
| SN74LVC2G17DCKR | Same SC70-6 package; 3000-unit reel vs. 250-unit small tape-and-reel (DCKTE4); identical parametric performance | Optimized for high-volume production; DCKTE4 targets prototyping and low-MOQ design-in | Choose DCKR for cost-sensitive volume manufacturing; retain DCKTE4 for NPI validation and engineering samples |

This eliminates external level shifters in mixed-voltage systems and is confirmed in Section 7.3 (Recommended Operating Conditions) and Feature Description of the SCES381N datasheet.
Does SN74LVC2G17DCKTE4 support partial power-down operation?
Yes, SN74LVC2G17DCKTE4 includes Ioff circuitry that disables outputs and limits leakage to ±10 μA when VCC = 0 V, preventing damaging back-current during live insertion or partial-power-down sequences. This capability is explicitly specified in Section 9.3 (Feature Description) and Electrical Characteristics Table 7.5 under Ioff parameter.
What are the Schmitt-trigger input thresholds for SN74LVC2G17DCKTE4 at 3.3 V supply?
At VCC = 3.3 V, SN74LVC2G17DCKTE4 has VT+ = 2.0 V (positive-going threshold) and VT– = 1.3 V (negative-going threshold), yielding 0.7 V hysteresis. These values are measured across –40°C to 125°C and documented in Table 7.5 (Electrical Characteristics) of the SCES381N datasheet.
Which package type does SN74LVC2G17DCKTE4 use, and what are its dimensions?
SN74LVC2G17DCKTE4 uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body size, 0.65 mm lead pitch, and 6-terminal surface-mount configuration. Mechanical data is provided in the Package Information section and Orderable Addendum of SCES381N, confirming DCK as the package code for this variant.
Can SN74LVC2G17DCKTE4 drive a 50 pF load within its specified propagation delay?
