Product details
Overview
SN74LVC2G17DCKT 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 live insertion via Ioff partial-power-down protection. It is used in audio docks, SSDs, and portable consumer interfaces requiring robust signal conditioning.
For engineers reviewing the SN74LVC2G17DCKT datasheet, SN74LVC2G17DCKT pinout, SN74LVC2G17DCKT application, or SN74LVC2G17DCKT equivalent, this page provides verified package mapping (SC70-6), confirmed Schmitt thresholds (VT+ = 2.0 V / VT– = 1.3 V at 3 V), Ioff behavior, NanoFree™ die-as-package construction, and real-world timing and drive specifications per SCES381N Rev. N.
Technical Context
The SN74LVC2G17DCKT implements two independent noninverting Schmitt-trigger buffers with asymmetric input thresholds-VT+ and VT– differ by up to 1.4 V-to reject slow-rising or noisy signals. Its Ioff circuitry actively disables outputs when VCC = 0 V, blocking back-drive current and enabling hot-plug capability.
It operates across –40°C to +125°C with full specification compliance, accepts 5.5 V-tolerant inputs regardless of VCC level (enabling voltage translation), and features low ICC (10 μA max) and low ground bounce (VOLP < 0.8 V at 3.3 V).
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 domains |
| Max tpd | 5.4 ns at 3.3 V - ensures sub-6 ns signal propagation for high-speed interface buffering |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads without external buffers |
| Input Threshold Hysteresis | ΔVT = 1.1 V typical at 3 V - rejects noise spikes ≤1.1 V and prevents chatter on slow edges |
| Ioff Current | ±10 μA max - blocks damaging back-current during power sequencing or board hot-swap |
| ESD Rating | 2000 V HBM - meets industrial-level electrostatic discharge immunity requirements |
| Operating Temp | –40°C to +125°C - qualified for extended-temperature embedded and automotive-adjacent applications |
Pinout & Package
SN74LVC2G17DCKT uses the SC70-6 (DCK) package: 2.00 mm × 1.25 mm body, 0.65 mm pitch, 6-pin surface-mount plastic case with exposed pad not present. Pin 1 is marked by a dot; orientation follows JEDEC MO-203-DA standard.
| 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 for all internal circuitry and output drivers; must be low-impedance |
| 2A | Input 2 | Noninverting Schmitt-trigger input for second buffer channel; electrically isolated from 1A |
| 1Y | Output 1 | Buffered, hysteresis-filtered replica of 1A; drives CMOS/TTL loads with rail-to-rail swing |
| VCC | Power Supply | Single supply pin for core logic and output drivers; bypassing with 0.1 μF capacitor required |
| 2Y | Output 2 | Buffered, hysteresis-filtered replica of 2A; independently driven with same specs as 1Y |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | VT+ = 2.0 V and VT– = 1.3 V (typical at 3 V) provide 0.7 V noise margin against false triggering |
| Ioff partial-power-down | Enables safe insertion into powered-backplane systems by disabling outputs when VCC = 0 V |
| 5.5 V tolerant inputs | Allows direct interfacing with 5 V legacy signals while operating from 1.8 V or 3.3 V supplies |
| NanoFree™ packaging | Diesize-only SC70 footprint (2.00 mm × 1.25 mm) reduces PCB area and thermal resistance vs. SOT-23 |
| Low dynamic power | Cpd = 19 pF at 3.3 V enables <1 mW operation at 10 MHz, critical for battery-powered devices |
Applications
| Audio Dock Interface | SSD Power Sequencing |
|---|---|
|
Use Scenario: Level-shifting and noise filtering of USB/UART control signals between 5 V host and 3.3 V audio dock MCU. IC Role / Device Role / Timing Role: Dual Schmitt buffer isolates and cleans reset, enable, and status lines with hysteresis to prevent spurious toggling. Use Value: Eliminates need for discrete RC filters or additional logic; 5.5 V input tolerance allows direct connection to 5 V USB VBUS-sensed lines. |
Use Scenario: Conditioning power-good and enable signals in client SSDs where supply ramp rates vary across vendors. IC Role / Device Role / Timing Role: Buffers and debounces PWR_EN and PG# signals before feeding to NAND controller or PMIC. Use Value: ΔVT ≥ 0.4 V ensures reliable detection of slow-rising 3.3 V rails; Ioff prevents backfeed during cold-start sequencing. |
| Portable MP3 Player UI | Industrial Sensor Hub |
|
Use Scenario: Debouncing mechanical button inputs (play/pause, volume) connected to an ultra-low-power ARM Cortex-M0+. IC Role / Device Role / Timing Role: Schmitt-trigger buffer converts noisy, slow-switching tactile switch transitions into clean digital edges. Use Value: Reduces firmware debounce overhead; 10 μA ICC enables always-on wake-up capability without battery drain penalty. |
Use Scenario: Signal conditioning for analog sensor outputs digitized by a SAR ADC in a factory-floor environmental monitor. IC Role / Device Role / Timing Role: Buffers reference voltage enable and ADC start pulses in presence of EMI from nearby motor drives. Use Value: 2000 V HBM rating and 1.1 V hysteresis suppress line transients; operates reliably at 125°C ambient. |
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. DCK's 259°C/W; identical electrical specs | Larger footprint but better thermal performance; preferred for high-density boards with limited airflow | Select DBVT when thermal headroom > electrical compatibility; DCK remains optimal for space-constrained layouts |
| NC7SZ17P5X | ON Semiconductor part; 1.65–5.5 V range; 5.5 ns tpd at 3.3 V; no Ioff support; 1.5 mm × 1.3 mm SOT-353 | Lacks Ioff and has lower ESD rating (1500 V HBM); smaller than DCK but no live-insertion capability | Choose NC7SZ17P5X only if Ioff and 2000 V HBM are unnecessary; verify system-level hot-swap safety separately |
Compared with SN74LVC2G17DBVT and NC7SZ17P5X, SN74LVC2G17DCKT uniquely combines NanoFree™ miniaturization, guaranteed Ioff, and full 2000 V HBM protection-making it the only option qualified for compact, hot-pluggable, and ESD-critical designs.

FAQ
What is the maximum operating temperature for SN74LVC2G17DCKT?
The SN74LVC2G17DCKT is fully specified from –40°C to +125°C ambient temperature per SCES381N Rev. N. This extended range supports deployment in automotive-adjacent environments, industrial enclosures, and thermally demanding SSD modules where junction temperatures may exceed 100°C under sustained load.
Does SN74LVC2G17DCKT support voltage translation between 5 V and 3.3 V logic?
Yes, SN74LVC2G17DCKT supports bidirectional voltage translation: its inputs tolerate up to 5.5 V regardless of VCC level, allowing 5 V signals to safely drive the device while operating from 3.3 V or 1.8 V. Outputs swing rail-to-rail, enabling clean 3.3 V output generation from 5 V inputs.
How does the Ioff feature function in SN74LVC2G17DCKT during power-down?
In SN74LVC2G17DCKT, the Ioff circuitry disables both outputs when VCC = 0 V, limiting Ioff current to ±10 μA max. This prevents back-driving current from live system buses into the unpowered IC-critical for hot-swap applications like modular audio docks or field-replaceable SSD carriers.
What is the typical hysteresis voltage (ΔVT) of SN74LVC2G17DCKT at 3.3 V supply?
At VCC = 3.3 V and TA = 25°C, SN74LVC2G17DCKT exhibits typical hysteresis ΔVT = VT+ – VT– = 1.1 V (with VT+ = 2.0 V and VT– = 0.9 V). This 1.1 V window ensures reliable rejection of noise spikes and eliminates chatter on slow-rising or degraded signal edges.
Is SN74LVC2G17DCKT pin-compatible with other packages in the SN74LVC2G17 family?
No-SN74LVC2G17DCKT uses SC70-6 (DCK) packaging with 0.65 mm pitch and 2.00 mm × 1.25 mm body, differing mechanically from SOT-23 (DBV), SON (DRY/DSF), and DSBGA (YZP) variants. While electrically identical, PCB layout and reflow profiles must be validated per package-specific thermal and mechanical requirements.
