Product details
Overview
SN74LVC1G17DCK3 from Texas Instruments is a single Schmitt-trigger buffer IC designed for noise-immune signal conditioning in 1.65V–5.5V systems. It provides hysteresis (ΔVT = 0.51V min at 3V), 4.6ns max propagation delay at 3.3V, ±24mA output drive, and 5.5V-tolerant inputs - enabling level translation and robust interfacing in portable audio and SSD control paths.
For engineers reviewing the SN74LVC1G17DCK3 datasheet, SN74LVC1G17DCK3 pinout, SN74LVC1G17DCK3 application, or SN74LVC1G17DCK3 equivalent, key selection criteria include Schmitt-trigger input thresholds (VT+ = 1.48V, VT− = 0.89V at 3V), Ioff support for live insertion, ultra-compact SC70-5 package (2.0mm × 2.1mm), and guaranteed operation from −40°C to 125°C.
Technical Context
The SN74LVC1G17DCK3 implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds to reject slow-rising or noisy signals. Its CMOS design delivers rail-to-rail output swing and supports mixed-voltage system interfacing via 5.5V-tolerant inputs independent of VCC.
It features Ioff circuitry that disables outputs and blocks current flow when VCC = 0V, enabling safe partial-power-down operation in hot-swap and battery-backed subsystems. The device meets JESD78 Class II latch-up immunity (>100mA) and exceeds JEDEC ESD standards (2000V HBM, 1000V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Threshold Hysteresis (ΔVT) | 0.51V min at 3V - rejects noise up to ±255mV on input signal without false triggering |
| Max Propagation Delay | 4.6ns at VCC = 3.3V, CL = 15pF - supports clean signal routing up to ~100MHz digital timing margins |
| Output Drive Strength | ±24mA at VCC = 3.3V - drives multiple LVC loads or moderate capacitive traces without external buffering |
| Ioff Current | ±10μA max - prevents back-drive damage during power sequencing or board insertion |
| ESD Rating (HBM) | ±2000V - meets industrial handling requirements without additional protection circuitry |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output return path |
| 2 | A | Noise-immune Schmitt-trigger input; accepts 0–5.5V regardless of VCC |
| 3 | N.C. | No internal connection - must be left floating or tied to GND per layout guidelines |
| 4 | Y | Noninverting buffered output; rail-to-rail swing, ±24mA capable |
| 5 | VCC | Primary power supply; powers internal logic and output stage; requires local 0.1μF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input hysteresis | Guaranteed ΔVT ≥ 0.51V at 3V enables reliable switching on slow or noisy signals (e.g., mechanical switch debouncing) |
| 5.5V-tolerant inputs | Allows direct connection to 5V sources while operating at 1.8V/2.5V/3.3V VCC - eliminates level-shifter components |
| Ioff partial-power-down | Blocks current flow between powered and unpowered sections - essential for hot-plug SSD modules and modular audio docks |
| Ultra-small SC70-5 footprint | 2.0mm × 2.1mm area saves >60% board space vs. SOT-23-5 - critical for thin client tablets and wireless headsets |
| High ESD robustness | 2000V HBM rating reduces field failure risk in handheld assembly and end-user handling scenarios |
Applications

Use Value: Enables direct sensor interface without external op-amp or regulator - reducing BOM count and calibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | SOT-23-5 package (2.9mm × 2.8mm); higher thermal resistance (RθJA = 357°C/W vs. 371°C/W) | Less suitable for space-constrained PCBs but offers better thermal dissipation in high-current continuous drive | Choose DBVR for designs requiring easier hand-soldering or higher sustained output current at elevated ambient temperatures |
| NC7SZ17P5X | SC70-5 package; lower drive (±24mA only at 3.3V, not guaranteed at 1.8V); no Ioff specification | Lacks Ioff and full 1.65–5.5V VCC range - unsuitable for hot-swap or mixed-rail systems | Choose NC7SZ17P5X only for cost-sensitive, single-rail 3.3V applications where partial-power-down is not required |

FAQ
What is the function of SN74LVC1G17DCK3?
The SN74LVC1G17DCK3 is a single noninverting Schmitt-trigger buffer performing Y = A. Its hysteresis (VT+ = 1.48V, VT− = 0.89V at 3V) rejects noise on slow or noisy inputs, and its 5.5V-tolerant inputs allow level translation across mixed-voltage domains. The SN74LVC1G17DCK3 operates from 1.65V to 5.5V and supports Ioff for partial-power-down use cases.
Does SN74LVC1G17DCK3 support hot-plug operation?
Yes, SN74LVC1G17DCK3 supports hot-plug operation via its Ioff feature. When VCC = 0V, the outputs enter high-impedance state and block current flow from powered inputs or outputs, preventing back-drive damage. This capability is verified per JESD78 Class II latch-up testing and makes SN74LVC1G17DCK3 suitable for modular SSD and audio dock designs requiring live insertion.
What is the maximum propagation delay of SN74LVC1G17DCK3 at 3.3V?
The maximum propagation delay of SN74LVC1G17DCK3 is 4.6ns at VCC = 3.3V, CL = 15pF, and TA = −40°C to 85°C. At extended temperature (−40°C to 125°C), the max tpd increases to 6.5ns under same load conditions. These values are measured from input transition (10% to 90%) to output transition (10% to 90%) and are guaranteed across process, voltage, and temperature corners.
Can SN74LVC1G17DCK3 interface a 5V sensor with a 1.8V microcontroller?
Yes, SN74LVC1G17DCK3 can safely interface a 5V sensor to a 1.8V microcontroller. Its inputs accept voltages up to 5.5V regardless of VCC, and its output swings rail-to-rail (0V to 1.8V) when powered at 1.8V. The SN74LVC1G17DCK3 maintains full Schmitt-trigger hysteresis and timing specs across the 1.65–5.5V VCC range, ensuring noise immunity and predictable switching.
What package type does SN74LVC1G17DCK3 use, and what are its dimensions?
SN74LVC1G17DCK3 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm nominal height, 0.65mm lead pitch, and 5 terminals. Pin 1 is GND, pin 2 is input A, pin 3 is no-connect, pin 4 is output Y, and pin 5 is VCC. The package is RoHS-compliant, lead-free (NiPdAu finish), and rated MSL-1 for unlimited floor life at ≤30°C/60% RH.
