Product details
Overview
SN74LVC1G17MDCKREP from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65-V to 5.5-V operation, delivering 4.6 ns max propagation delay at 3.3 V, ±24 mA output drive, and Ioff support for partial power-down mode. It performs Y = A logic with hysteresis (ΔVT = 0.51–0.83 V at 3 V), enabling robust noise immunity in signal conditioning applications such as sensor interface and clock clean-up.
For engineers reviewing the SN74LVC1G17MDCKREP datasheet, SN74LVC1G17MDCKREP pinout, SN74LVC1G17MDCKREP application, or SN74LVC1G17MDCKREP equivalent, key selection considerations include its SC-70 (DCK) 5-pin package, –55°C to 125°C extended temperature range, Schmitt-trigger input thresholds (VT+ = 1.48–1.92 V, VT– = 0.89–1.2 V at 3 V), and compatibility with mixed-voltage systems up to 5.5 V.
Technical Context
This device implements a noninverting Schmitt-trigger buffer with asymmetric input thresholds to reject noise on slow or noisy digital signals. Its Ioff circuitry actively disables outputs during power-down, preventing back-current flow when VCC = 0 V while inputs remain biased.
It operates across 1.65–5.5 V supply range with rail-to-rail output swing, supports 15 pF load at ≤4.6 ns tpd (3.3 V), and meets JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM). The NanoStar™ SC-70 package uses die-as-package construction for minimal footprint and thermal resistance (θJA = 252°C/W).
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 Propagation Delay | 4.6 ns at 3.3 V, CL = 15 pF - ensures timing-critical signal buffering in high-speed digital interfaces |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive multiple LVC loads or moderate PCB traces without external buffering |
| Hysteresis ΔVT | 0.51 V (min) to 0.83 V (max) at 3 V - provides noise margin against EMI and crosstalk in industrial sensor lines |
| Ioff Current | ±10 μA max at 5.5 V - guarantees isolation during hot-insertion or partial-power-down system states |
| Operating Temperature | –55°C to 125°C - qualified per JEDEC standards for aerospace, defense, and under-hood automotive use |
| Input Thresholds (3 V) | VT+ = 1.48–1.92 V, VT– = 0.89–1.2 V - enables reliable switching on slowly rising/falling waveforms |
Pinout & Package
SN74LVC1G17MDCKREP is housed in a 5-pin SC-70 (DCK) package measuring 2.15 mm × 1.85 mm × 1.1 mm (max height), with lead pitch of 0.65 mm and moisture sensitivity level (MSL) 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect terminal | Internally unconnected; must be left floating or tied to GND/VCC per layout best practice - no electrical function |
| 2 (A) | Schmitt-trigger input | Accepts 1.65–5.5 V logic signals; hysteresis prevents chatter on noisy or slow edges |
| 3 (GND) | Ground reference | Primary return path for all internal current; requires low-inductance connection to system ground plane |
| 4 (Y) | Noninverting buffered output | Delivers rail-to-rail CMOS output with ±24 mA drive; compatible with LVC/LVT/ALVC families |
| 5 (VCC) | Power supply | Supplies core logic and output drivers; bypass capacitor (0.1 μF) required within 3 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input with programmable hysteresis | Enables reliable signal restoration on degraded waveforms (e.g., RC-filtered sensor outputs or long traces) |
| Ioff partial power-down support | Prevents backflow current when VCC = 0 V, allowing safe insertion into live backplanes or multi-rail systems |
| NanoStar™ SC-70 package | Die-as-package construction reduces board area by >50% vs. SOT-23 while maintaining thermal performance |
| Extended temperature qualification | Validated via HAST, temperature cycling, and bond intermetallic life testing for mission-critical reliability |
| ESD robustness | 2000-V HBM rating eliminates need for external protection diodes in most industrial I/O designs |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Conditioning analog-output sensor signals (e.g., thermistor, potentiometer) before ADC sampling or microcontroller GPIO capture. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising voltage ramps and rejects line noise induced by motor switching or RF sources. Use Value: Eliminates false triggering in threshold-detection circuits without requiring external RC filtering or comparator ICs. |
Use Scenario: Debouncing mechanical switch inputs (e.g., door latch, seat position sensors) in 12-V vehicle subsystems with 3.3-V MCU logic. IC Role / Device Role / Timing Role: Noninverting buffer with hysteresis converts noisy switch bounce into clean digital transitions for interrupt-driven firmware. Use Value: Reduces firmware debounce overhead and avoids missed events caused by sub-microsecond transients. |
| High-Speed Clock Clean-Up | Legacy Bus Signal Translation |
|
Use Scenario: Restoring edge integrity of degraded clock signals distributed across multi-layer PCBs in FPGA or DSP timing paths. IC Role / Device Role / Timing Role: Low-tpd Schmitt buffer retimes jittery clocks and suppresses overshoot/ringing from impedance mismatches. Use Value: Enables stable clock distribution without adding PLL latency or requiring higher-cost clock conditioners. |
Use Scenario: Level-shifting and noise rejection between 5-V legacy peripherals (e.g., UART modems, SPI EEPROMs) and modern 3.3-V SoCs. IC Role / Device Role / Timing Role: Voltage-tolerant input accepts 5-V signals while driving 3.3-V logic; hysteresis rejects coupling noise from shared power rails. Use Value: Replaces discrete resistor-divider + comparator solutions with single-chip reliability and smaller footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum operating voltage for SN74LVC1G17MDCKREP?
The SN74LVC1G17MDCKREP supports a supply voltage range of 1.65 V to 5.5 V. Absolute maximum rating is 6.5 V on VCC, but sustained operation above 5.5 V violates recommended conditions and risks parametric shift or reliability degradation. All DC and AC specifications are guaranteed only within the 1.65–5.5 V range.
Does SN74LVC1G17MDCKREP support partial power-down mode?
Yes, SN74LVC1G17MDCKREP features Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff current to ±10 μA max. This prevents damaging back-current flow when the device is powered down while inputs remain active - essential for hot-swap and multi-rail system designs.
What is the hysteresis voltage (ΔVT) of SN74LVC1G17MDCKREP at 3.3 V supply?
At VCC = 3.3 V, the SN74LVC1G17MDCKREP exhibits VT+ = 1.48–1.92 V and VT– = 0.89–1.2 V, yielding a hysteresis window (ΔVT) of 0.51–0.83 V. This ensures robust noise rejection on slow or noisy input signals without requiring external components.
Can SN74LVC1G17MDCKREP drive a 50-pF load within its specified propagation delay?
Yes - at VCC = 3.3 V and CL = 50 pF, the SN74LVC1G17MDCKREP maintains a maximum tpd of 5.5 ns, as verified in the switching characteristics table. This confirms suitability for driving moderately capacitive loads like longer PCB traces or multiple fan-out gates without violating timing budgets.
Is SN74LVC1G17MDCKREP pin-compatible with SN74LVC1G17MDBVREP?
No - SN74LVC1G17MDCKREP uses the SC-70 (DCK) 5-pin package with 0.65-mm pitch and 2.15 mm × 1.85 mm footprint, while SN74LVC1G17MDBVREP uses SOT-23 (DBV) with 0.95-mm pitch and 2.92 mm × 1.3 mm footprint. Pin numbering and physical layout differ; PCB redesign is required for substitution.
