Product details
Overview
SN74LVC1G17DCKJ from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V VCC operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for portable audio and display interfaces.
For engineers reviewing the SN74LVC1G17DCKJ datasheet, SN74LVC1G17DCKJ pinout, SN74LVC1G17DCKJ application, or SN74LVC1G17DCKJ equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for industrial and consumer electronics design.
Technical Context
The SN74LVC1G17DCKJ implements a noninverting Schmitt-trigger buffer (Y = A) with hysteresis (ΔVT = 0.36–1.04V across VCC), enabling robust noise rejection on slow-rising or noisy digital signals. Its Ioff feature isolates inputs/outputs during partial power-down, supporting live insertion and back-drive protection.
It operates across –40°C to 125°C with rail-to-rail output swing (VOH ≥ VCC – 0.1V, VOL ≤ 0.1V), supports voltage translation (e.g., 5V input → 3.3V output), and maintains low static current (ICC ≤ 10μA) while driving up to ±24mA per output at 3.3V.
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 Voltage Tolerance | Up to 5.5V - allows 5V signals into lower-VCC systems without level shifters |
| tpd (max) | 4.6ns at 3.3V, CL = 15pF - supports clean signal buffering up to ~100MHz edge rates |
| Output Drive | ±24mA at 3.3V - sufficient to drive multiple CMOS loads or moderate capacitive traces |
| Hysteresis (ΔVT) | 0.51V typical at 3V VCC - rejects >500mV of input noise without false triggering |
| Ioff | ≤ ±10μA at VCC = 0V - prevents back-current during hot-swap or power sequencing |
| ESD Rating | ±2000V HBM - meets industrial handling requirements without external protection |
Pinout & Package
SN74LVC1G17DCKJ uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body, 0.65mm pitch, 5-pin surface-mount with exposed pad not present. Pin 1 is marked by a dot; device orientation follows JEDEC MO-203-DA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output return path |
| 2 | A | Noninverting Schmitt-trigger input - accepts 0–5.5V, triggers at VT+ / VT− thresholds |
| 3 | Y | Buffered output - rail-to-rail swing, ±24mA drive capability, 5.5V-tolerant when high-impedance |
| 4 | N.C. | No internal connection - must be left unconnected or tied to GND/VCC per layout guidelines |
| 5 | VCC | Power supply - decoupling capacitor (0.1μF) required within 2mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.36–1.04V hysteresis to reject noise on slow or noisy control lines (e.g., pushbutton debouncing, sensor outputs) |
| Ioff partial-power-down | Enables safe hot-plug operation and prevents back-current when VCC is off, critical for modular systems |
| 5.5V-tolerant inputs | Eliminates need for external level translators when interfacing 5V legacy peripherals to 3.3V or 1.8V SoCs |
| Ultra-low ICC | ≤10μA quiescent current supports battery-powered devices requiring multi-year standby life |
| Wide temperature range | –40°C to +125°C operation ensures reliability in automotive infotainment and industrial displays |
Applications
| Audio Dock Interface | SSD Power Sequencing Control |
|---|---|
Use Scenario: Signal conditioning between USB-C audio controller and analog codec in portable docking stations. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans up slow-rising enable signals and isolates noise from shared PCB ground planes. Use Value: Prevents spurious codec activation during plug-in events; 5.5V tolerance accommodates 5V USB-PD signaling without added components. |
Use Scenario: Enabling/disabling 12V DC-DC converters in client SSD modules based on host PCIe reset assertion. IC Role / Device Role / Timing Role: Noninverting buffer with hysteresis converts noisy PCIe RST# (3.3V LVTTL) into clean, robust enable logic for power management ICs. Use Value: Eliminates false resets caused by ground bounce or EMI; Ioff prevents backfeed when SSD is powered down but host remains active. |
| Blu-ray Player Front Panel | HDTV HDMI Hot-Plug Detection |
Use Scenario: Debouncing mechanical buttons and IR receiver outputs in Blu-ray player front panel control logic. IC Role / Device Role / Timing Role: Single-buffer Schmitt trigger converts erratic switch closures into clean digital edges for microcontroller GPIO. Use Value: Reduces firmware debounce overhead; 24mA drive supports long trace runs to remote panel assemblies without signal degradation. |
Use Scenario: Conditioning HPD (Hot-Plug Detect) signal from HDMI source to SoC GPIO in high-definition TV mainboards. IC Role / Device Role / Timing Role: Level-shifting buffer translates 5V HPD presence signal to 3.3V-compatible input while rejecting ESD-induced transients. Use Value: Meets HDMI compliance for HPD noise immunity; ±2000V HBM rating eliminates need for discrete TVS diodes on HPD line. |
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 | Same silicon, SOT-23-5 package (2.9mm × 1.6mm body); 357.1°C/W θJA; no N.C. pin - pin 1 = A, pin 2 = Y, pin 3 = GND, pin 4 = VCC, pin 5 = N.C. | Larger footprint; higher thermal resistance; preferred where board space permits and hand-soldering is used. | Select DBVR for prototyping or legacy designs using SOT-23 footprints; verify PCB land pattern compatibility before substitution. |
| NC7SZ17P5X | ON Semiconductor part; same function, SC70-5; 3.5ns tpd at 3.3V; 1.65–5.5V VCC; ±24mA drive; but only rated to 85°C ambient (not 125°C). | Not suitable for under-hood automotive or high-temp industrial environments where full –40°C to 125°C operation is required. | Choose NC7SZ17P5X only for cost-sensitive consumer applications with <85°C operating limits and verified layout compatibility. |
Compared with SN74LVC1G17DCKJ, SN74LVC1G17DBVR offers identical electrical performance in a larger, more manufacturable package, while NC7SZ17P5X trades extended temperature support for marginally faster timing - making SN74LVC1G17DCKJ the optimal choice for space-constrained, thermally demanding embedded systems.

FAQ
What is the maximum operating temperature for SN74LVC1G17DCKJ?
The SN74LVC1G17DCKJ is fully specified from –40°C to +125°C ambient temperature. This extended range supports deployment in automotive infotainment head units, industrial SSD controllers, and outdoor digital signage where thermal margins are tight. The DCK package's 340°C/W junction-to-ambient thermal resistance requires adequate copper pour and airflow in high-power-density layouts.
Does SN74LVC1G17DCKJ support 5V input signals when powered at 3.3V?
Yes, SN74LVC1G17DCKJ accepts input voltages up to 5.5V regardless of VCC level - including when VCC = 3.3V. This 5V-tolerant input enables direct interfacing with legacy 5V peripherals (e.g., HDMI HPD, USB VBUS detection) without external level shifters, simplifying BOM and reducing board area.
How does the Schmitt-trigger action benefit SN74LVC1G17DCKJ in real designs?
The SN74LVC1G17DCKJ's hysteresis (ΔVT = 0.51V typical at 3V) prevents multiple output transitions caused by slow-rising or noisy inputs - such as mechanical switch bounce, long cable reflections, or sensor output drift. This eliminates software debounce overhead and improves system reliability in audio docks and front-panel controls.
Can SN74LVC1G17DCKJ be used in hot-swap applications?
Yes, SN74LVC1G17DCKJ includes Ioff circuitry that disables outputs and limits leakage to ≤±10μA when VCC = 0V. This protects upstream drivers and downstream loads during live insertion - essential for modular SSD carriers, field-replaceable display modules, and dockable computing accessories using the SN74LVC1G17DCKJ.
What is the recommended bypass capacitor for SN74LVC1G17DCKJ?
A 0.1μF ceramic capacitor placed within 2mm of the SN74LVC1G17DCKJ VCC pin (Pin 5) and GND (Pin 1) is mandatory for stable operation. For systems with high-frequency noise or multiple logic devices, paralleling a 1μF capacitor nearby further suppresses broadband ripple - especially critical in portable audio and HDMI interface applications using SN74LVC1G17DCKJ.
