Product details
Overview
SN74LVC2G17DCKTG4 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 delivers ±24 mA output drive at 3.3 V, achieves 5.4 ns max propagation delay at 3.3 V, and supports Ioff partial-power-down mode for live insertion in portable audio and SSD power sequencing applications.
For engineers reviewing the SN74LVC2G17DCKTG4 datasheet, SN74LVC2G17DCKTG4 pinout, SN74LVC2G17DCKTG4 application, or SN74LVC2G17DCKTG4 equivalent, key selection criteria include its SC70-6 package footprint, 5.5 V-tolerant inputs, Schmitt-trigger threshold asymmetry (VT+ = 2.0 V / VT– = 1.3 V at 3 V), and Ioff-enabled back-drive protection during system power transitions.
Technical Context
This device implements two independent noninverting buffers with Schmitt-trigger inputs, enabling robust signal conditioning of slow or noisy digital signals. Its hysteresis (ΔVT = 0.7 V typical at 3 V) rejects noise between VT+ and VT– thresholds, while Ioff circuitry disables outputs when VCC = 0 V to prevent current backflow.
The SN74LVC2G17DCKTG4 operates across –40°C to 125°C, supports voltage translation (e.g., 5 V input to 3.3 V or 1.8 V output), and features 10 μA max ICC at 25°C - critical for low-power portable systems requiring stable logic-level buffering without external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across legacy and modern logic families including 1.8 V, 2.5 V, 3.3 V, and 5 V systems. |
| Max tpd | 5.4 ns at 3.3 V - ensures timing-critical signal routing in high-speed consumer interfaces like USB power control and display data paths. |
| Output Drive | ±24 mA at 3.3 V - drives moderate capacitive loads (e.g., 50 pF) without external buffers in audio dock and tablet I/O expansion circuits. |
| Hysteresis ΔVT | 0.7 V typical at 3 V - suppresses false triggering from EMI or slow-edge signals in power button debouncing and sensor interface applications. |
| Ioff Current | ±10 μA max - isolates powered-down sections during hot-swap events in SSDs and enterprise tablets, preventing bus contention and latch-up. |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V microcontrollers or legacy peripherals without level-shifting components. |
| ESD Rating | 2000 V HBM - meets industrial handling requirements for assembly-line integration into AV receivers and Blu-ray players. |
Pinout & Package
SN74LVC2G17DCKTG4 uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body size, 0.65 mm pitch, 6-pin surface-mount outline optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Noninverting Schmitt-trigger input for first buffer channel; accepts 0–5.5 V regardless of VCC. |
| GND | Ground | Reference node for all logic levels and output drive; must be low-impedance for stable VOL/VOH. |
| 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 with Ioff disable. |
| VCC | Power Pin | Supply input for internal logic and output drivers; requires local 0.1 μF bypass capacitor per TI layout guidelines. |
| 2Y | Output 2 | Buffered noninverting output corresponding to 2A; shares VCC/GND but operates independently of 1Y. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.7 V typical hysteresis at 3 V to reject noise on slow-rising signals such as mechanical switch inputs or analog sensor outputs. |
| Ioff partial-power-down | Disables outputs and limits leakage to ±10 μA when VCC = 0 V - essential for hot-plug SSD modules and modular docking stations. |
| NanoFree™ packaging | Uses die-as-package construction in SC70-6 to reduce footprint by >30% vs. SOT-23, enabling denser layouts in tablets and wireless headsets. |
| 5-V tolerant inputs | Accepts 5.5 V inputs while operating at 1.65–3.3 V VCC - eliminates external level shifters in mixed-voltage audio docks and PDA peripheral interfaces. |
| Low ICC | 10 μA max supply current at 25°C - extends battery life in always-on power monitoring circuits for telecom AC/DC supplies. |
Applications
| Audio Dock Signal Conditioning | SSD Power Sequencing Control |
|---|---|

IC Role / Device Role / Timing Role: Schmitt-trigger buffer driving LED indicators and debouncing tactile switches connected to microcontroller GPIOs. Use Value: 2000 V HBM ESD rating and Ioff protection ensure reliability during field service, while low ICC (<10 μA) minimizes standby power in always-on TV modes. |
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 |
|---|---|---|---|
| SN74LVC2G17DBVTG4 | 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 suits manual assembly or prototyping; higher thermal resistance limits high-density automated placement. | Select when board real estate permits larger package or when compatibility with legacy SOT-23 footprints is required. |
| SN74LVC1G17DCKR | Single-channel version in same SC70-6 package; no dual functionality; otherwise identical VCC range, Ioff, and hysteresis. | Requires two devices for dual-buffer functions; increases BOM count and layout area versus integrated dual-channel solution. | Choose only if design needs only one buffered channel and seeks minimal inventory SKU count. |
Compared with SN74LVC2G17DBVTG4 and SN74LVC1G17DCKR, the SN74LVC2G17DCKTG4 uniquely combines dual-channel buffering, SC70-6 miniaturization, and full Ioff support - making it optimal for space-constrained, multi-rail consumer electronics where both channels are utilized.

FAQ
What is the maximum operating temperature for SN74LVC2G17DCKTG4?
The SN74LVC2G17DCKTG4 is rated for operation from –40°C to +125°C ambient temperature, fully specified across this range per its Recommended Operating Conditions table. This extended range supports deployment in thermally demanding environments such as enclosed AV receivers, server SSDs, and industrial tablets where internal board temperatures exceed 85°C.
Does SN74LVC2G17DCKTG4 support level translation between different supply voltages?
Yes, SN74LVC2G17DCKTG4 supports down-translation: its 5.5 V-tolerant inputs allow 5 V signals to be safely applied while VCC is at 1.65 V, 1.8 V, 2.5 V, or 3.3 V. The output swings rail-to-rail relative to VCC, enabling clean 3.3 V or 1.8 V logic generation from a 5 V source - ideal for interfacing legacy peripherals to modern low-voltage processors.
How does the Ioff feature function in SN74LVC2G17DCKTG4 during power-down?
In SN74LVC2G17DCKTG4, the Ioff circuitry actively disables both outputs when VCC = 0 V, limiting input/output leakage to ±10 μA. This prevents damaging back-current flow from live system buses into a powered-down subsystem - a critical capability for hot-pluggable SSD modules and modular docking stations where partial power-down is routine.
What is the typical hysteresis voltage (ΔVT) of SN74LVC2G17DCKTG4 at 3.3 V supply?
At VCC = 3.3 V and TA = 25°C, SN74LVC2G17DCKTG4 exhibits a typical hysteresis voltage ΔVT of 0.7 V, calculated as VT+ (2.0 V) minus VT– (1.3 V). This value ensures reliable rejection of noise spikes up to ±350 mV on input signals - sufficient for mechanical switch debouncing and noisy sensor interface applications without external filtering.
Is SN74LVC2G17DCKTG4 compatible with lead-free reflow processes?
Yes, SN74LVC2G17DCKTG4 carries a Level-1 moisture sensitivity rating with peak reflow temperature of 260°C, fully compliant with lead-free soldering profiles. Its NIPDAU lead finish and SC70-6 package are qualified for standard JEDEC J-STD-020 reflow cycles, supporting high-yield manufacturing in RoHS-compliant consumer electronics assembly lines.
