Product details
Overview
SN74LVC1G17DCKTG4 from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in noise-prone or slow-rising digital interfaces. It operates from 1.65V to 5.5V VCC, delivers ±24mA output drive at 3.3V, achieves 4.6ns max propagation delay, and features 5.5V-tolerant inputs-enabling level translation in portable audio and SSD control paths.
For engineers reviewing the SN74LVC1G17DCKTG4 datasheet, SN74LVC1G17DCKTG4 pinout, SN74LVC1G17DCKTG4 application, or SN74LVC1G17DCKTG4 equivalent, key selection criteria include its ultra-compact SC70-5 package (2.0mm × 2.1mm), Ioff support for live insertion, hysteresis-based noise immunity (ΔVT = 0.64V at 3V), and guaranteed operation across –40°C to 125°C.
Technical Context
The SN74LVC1G17DCKTG4 implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds: VT+ = 1.48V and VT– = 0.89V at VCC = 3V, yielding 0.59V hysteresis. Its CMOS design maintains low static current (ICC ≤ 10μA) while supporting rail-to-rail output swing and 5.5V input tolerance independent of VCC.
This device uses TI's LVC logic family architecture, enabling interoperability with 1.8V/2.5V/3.3V/5V systems. The Ioff feature actively disables outputs when VCC = 0V, preventing back-drive current and supporting partial-power-down modes required in hot-swap and battery-backed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and down-translation from 5V logic to lower-VCC domains |
| Input Voltage Tolerance | Up to 5.5V - allows connection to higher-voltage buses without external level shifters |
| Max Propagation Delay | 4.6ns at VCC = 3.3V, CL = 15pF - enables reliable operation in sub-100MHz clock/data paths |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive multiple LVC inputs or moderate capacitive loads (e.g., 20pF PCB traces) |
| Hysteresis (ΔVT) | 0.59V at VCC = 3V - rejects noise up to ~600mV peak-to-peak on slow or noisy signals |
| Ioff Current | ±10μA max - ensures safe isolation during power sequencing and prevents back-current in powered-down sections |
| Operating Temperature | –40°C to 125°C - qualified for automotive cabin, industrial control, and high-density SSD thermal environments |
Pinout & Package
SN74LVC1G17DCKTG4 is housed in a 5-pin SC70 (DCK) package measuring 2.0mm × 2.1mm with 0.65mm pitch. The package is RoHS-compliant, moisture-sensitive level 1 (MSL-1), and rated for reflow up to 260°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output return path |
| 2 | A | Noninverting Schmitt-trigger input - accepts 0V to 5.5V; threshold hysteresis enables noise margin |
| 3 | Y | Buffered output - rail-to-rail CMOS swing, ±24mA drive capability at 3.3V |
| 4 | N.C. | No internal connection - must be left unconnected or tied to GND per layout best practice |
| 5 | VCC | Power supply input - decoupling capacitor (0.1μF) required adjacent to pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.59V hysteresis at 3V - eliminates chatter on slow edges or EMI-coupled signals in audio docks and SSDs |
| 5.5V-tolerant inputs | Enables direct interface to 5V microcontrollers or legacy peripherals without level-shifting components |
| Ioff protection | Blocks current flow when VCC = 0V - critical for hot-plug SSD modules and modular telecom power supplies |
| Ultra-small SC70-5 footprint | 0.64mm² board area - saves space in space-constrained applications like wireless headsets and tablets |
| ESD robustness | 2000V HBM, 1000V CDM - meets IPC/JEDEC requirements for consumer electronics assembly and field reliability |

FAQ
What is the maximum operating temperature for SN74LVC1G17DCKTG4?
The SN74LVC1G17DCKTG4 is fully specified from –40°C to +125°C ambient temperature. This rating is validated per JEDEC JESD22-A108 and applies across the full VCC range (1.65V–5.5V). Thermal derating is not required within this range, making SN74LVC1G17DCKTG4 suitable for under-hood automotive modules and high-density SSD controllers where junction temperatures exceed 100°C.
Does SN74LVC1G17DCKTG4 support level translation between 5V and 3.3V systems?
Yes, SN74LVC1G17DCKTG4 supports bidirectional level translation: its inputs tolerate up to 5.5V regardless of VCC, allowing a 5V signal to drive the A input while VCC is set to 3.3V; the Y output then swings rail-to-rail between 0V and 3.3V. This eliminates external translators in mixed-voltage interfaces such as USB-to-audio codec links.
What is the purpose of the N.C. pin on SN74LVC1G17DCKTG4?
Pin 4 of SN74LVC1G17DCKTG4 is designated N.C. (No internal connection). It has no bond wire or circuit connection inside the die. TI recommends leaving this pin unconnected or tying it to GND for mechanical stability and EMI reduction-never connect it to VCC or a signal line, as that violates the device's internal isolation design.
How does the Schmitt-trigger action improve noise immunity in SN74LVC1G17DCKTG4?
SN74LVC1G17DCKTG4 uses separate positive-going (VT+ = 1.48V) and negative-going (VT– = 0.89V) input thresholds at 3V VCC, creating 0.59V hysteresis. This prevents multiple transitions when input signals cross the threshold slowly or with superimposed noise-critical for debouncing mechanical switches in wireless headsets or cleaning up noisy I²C clock lines in AV receivers.
Is SN74LVC1G17DCKTG4 compatible with lead-free reflow processes?
Yes, SN74LVC1G17DCKTG4 uses NiPdAu lead finish and is rated MSL-1 (Moisture Sensitivity Level 1) with peak reflow tolerance up to 260°C. It complies with IPC/JEDEC J-STD-020 and is qualified for standard Pb-free solder profiles including ramp-to-spike and soak profiles-no prebake required prior to assembly.
