Product details
Overview
SN74LVC1G17DCKRE4 from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for noise-immune signal conditioning in 1.65V–5.5V systems. It performs Y = A logic, 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 power sequencing applications.
For engineers reviewing the SN74LVC1G17DCKRE4 datasheet, SN74LVC1G17DCKRE4 pinout, SN74LVC1G17DCKRE4 application, or SN74LVC1G17DCKRE4 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.64V typ at 3V), Ioff support for live insertion, ultra-small SC70-5 package (2.0mm × 2.1mm), and guaranteed operation from –40°C to 125°C.
Technical Context
The SN74LVC1G17DCKRE4 implements a non-inverting Schmitt-trigger buffer with asymmetric input thresholds: VT+ = 1.48V and VT– = 0.89V at VCC = 3V, yielding 0.59V hysteresis. Its CMOS design enables rail-to-rail output swing and supports partial-power-down via Ioff, which disables outputs and blocks current flow when VCC = 0V.
This device operates across 1.65V–5.5V supply range while maintaining consistent timing and drive strength - e.g., tpd ≤ 4.6ns at 3.3V/CL = 15pF and ±24mA output capability. Input tolerance up to 5.5V allows interfacing with higher-voltage logic without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports mixed-voltage system interfacing and battery-powered designs down to 1.65V |
| Max Propagation Delay | 4.6ns at 3.3V, CL = 15pF - enables reliable operation in high-speed digital paths up to ~100MHz |
| Output Drive | ±24mA at 3.3V - drives multiple LVC loads or moderate capacitive loads without buffering |
| Input Voltage Tolerance | Up to 5.5V - permits 5V logic inputs into 3.3V or 2.5V systems without damage or level-shifting circuitry |
| Hysteresis (ΔVT) | 0.59V typical at VCC = 3V - rejects noise on slow or noisy signals such as reset lines or mechanical switch inputs |
| Ioff Current | ±10μA max - prevents back-drive and enables hot-swap capability in powered-backplane applications |
| ESD Rating | ±2000V HBM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
SN74LVC1G17DCKRE4 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm nominal height, 5-pin surface-mount with 0.65mm pitch. Pin 1 is marked by a dot; pin 3 is GND; pin 5 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Non-inverting Schmitt-trigger input; accepts 0–5.5V regardless of VCC |
| 2 | GND | Ground reference for all internal circuitry and output return path |
| 3 | Output (Y) | CMOS push-pull output; swings rail-to-rail with ±24mA drive at 3.3V |
| 4 | No Connect (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 5 | VCC | Power supply input; bypass with 0.1μF capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.59V typical hysteresis at 3V, eliminating chatter on slow-rising signals like microcontroller reset lines |

| Ioff partial-power-down | Blocks current flow between powered and unpowered sections, supporting hot-plug and modular system architectures |
| Ultra-small SC70-5 package | 0.64mm² footprint saves PCB area in space-constrained portable devices such as wireless headsets and SSD modules |
| Wide temperature range | Specified from –40°C to +125°C, suitable for automotive infotainment and industrial SSD controller environments |
Applications
| Audio Dock Interface | SSD Power Sequencing |
|---|---|
Use Scenario: Signal conditioning between 5V USB audio source and 3.3V codec in portable docking station. IC Role / Device Role / Timing Role: Non-inverting Schmitt buffer isolates noise-prone analog switch control lines and cleans up slow GPIO transitions. Use Value: Eliminates false triggering during plug/unplug events using 0.59V hysteresis; 5.5V-tolerant input avoids level-shifter BOM cost. | Use Scenario: Enabling clean power-up sequencing for NAND flash and controller rails in client SSD modules. IC Role / Device Role / Timing Role: Buffering enable signals from PMIC to voltage regulators, ensuring monotonic ramp-up under noisy board conditions. Use Value: ±24mA drive ensures fast edge rates into regulator EN pins; Ioff prevents backfeed when SSD is removed mid-operation. |
| TV Remote IR Receiver | Industrial Sensor Hub |
Use Scenario: Conditioning weak, noisy IR demodulator output before MCU interrupt input in LCD TV remote receivers. IC Role / Device Role / Timing Role: Schmitt-trigger buffer converts marginal analog-like IR pulses into clean digital logic levels. Use Value: 4.6ns propagation delay preserves pulse timing integrity; low 10μA ICC minimizes standby current in battery-operated remotes. | Use Scenario: Interfacing multiple analog sensor outputs (e.g., thermistors, pressure transducers) to a 3.3V microcontroller ADC reference chain. IC Role / Device Role / Timing Role: Level-shifting and noise filtering for sensor bias control lines operating in electrically noisy factory environments. Use Value: 125°C rating supports extended operation near heat-generating motors; ESD robustness reduces field failure in unshielded enclosures. |
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 for DCK) | Less board-area constrained designs; preferred where hand-soldering or thermal mass aids reflow | Select DBVR when larger footprint is acceptable and thermal margin above 125°C ambient is required |
| NC7SZ17P5X | SC70-5 package; lower drive (±24mA at 3.3V same), but narrower VCC range (1.65V–4.3V); no Ioff support | Not suitable for hot-swap or partial-power-down systems; limited to ≤4.3V supply domains | Choose NC7SZ17P5X only if Ioff is unnecessary and system VCC never exceeds 4.3V |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, SN74LVC1G17DCKRE4 uniquely combines ultra-compact SC70-5 packaging, full 5.5V input tolerance, and Ioff-enabled live insertion - making it optimal for space- and reliability-critical portable SSDs and audio docks.

FAQ
What is the maximum operating temperature for SN74LVC1G17DCKRE4?
The SN74LVC1G17DCKRE4 is fully specified from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters including propagation delay, output drive, and hysteresis, making SN74LVC1G17DCKRE4 suitable for under-hood automotive infotainment and industrial SSD controller applications where thermal stress is present.
Does SN74LVC1G17DCKRE4 support level translation?
Yes, SN74LVC1G17DCKRE4 supports down-translation: its inputs tolerate up to 5.5V independent of VCC, allowing 5V signals to safely drive the device when powered from 1.65V–3.3V supplies. However, output swing is rail-referenced to VCC, so it does not translate up - SN74LVC1G17DCKRE4 outputs cannot generate 5V logic levels when VCC = 3.3V.
What is the purpose of the N.C. pin on SN74LVC1G17DCKRE4?
Pin 4 of SN74LVC1G17DCKRE4 is designated No Connect (N.C.) - it has no internal connection and must remain unconnected. TI recommends leaving it floating; tying it to GND or VCC is unnecessary and may risk unintended coupling in high-frequency layouts. The N.C. pin exists for mechanical symmetry and package compatibility across the LVC1G family.
Can SN74LVC1G17DCKRE4 be used in hot-swap applications?
Yes, SN74LVC1G17DCKRE4 supports hot-swap via its Ioff feature: when VCC = 0V, the outputs enter high-impedance state and block current flow from live inputs or outputs, preventing back-drive damage. This behavior is tested and guaranteed per JESD78 Class II latch-up standards, making SN74LVC1G17DCKRE4 appropriate for modular SSD carriers and field-replaceable audio dock modules.
What bypass capacitor value is recommended for SN74LVC1G17DCKRE4?
A 0.1μF ceramic capacitor is recommended for SN74LVC1G17DCKRE4, placed as close as possible to the VCC (pin 5) and GND (pin 2) terminals. This value effectively suppresses high-frequency switching noise generated by the ±24mA output transitions. For systems with shared VCC rails, adding a bulk 1μF capacitor nearby further stabilizes low-frequency supply droop during burst-mode operation.
