Product details
Overview
SN74LVC1G17DCKRG4 from Texas Instruments is a single Schmitt-trigger buffer IC designed for 1.65V to 5.5V operation, delivering 24mA output drive at 3.3V, 4.6ns max propagation delay (CL = 15pF), and 5.5V-tolerant inputs - used in noise-immune signal conditioning for audio docks, SSDs, and HDTV timing paths.
For engineers reviewing the SN74LVC1G17DCKRG4 datasheet, SN74LVC1G17DCKRG4 pinout, SN74LVC1G17DCKRG4 application, or SN74LVC1G17DCKRG4 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.64V typ at 3V), Ioff support for live insertion, ±24mA drive capability, and SC70-5 package compatibility with high-density portable designs.
Technical Context
The SN74LVC1G17DCKRG4 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 architecture enables rail-to-rail output swing and supports voltage translation from 5.5V inputs down to lower VCC levels.
It operates across –40°C to 125°C with full Ioff functionality, disabling outputs and blocking current flow when VCC = 0V - critical for partial-power-down systems. The device meets JESD 78 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 interoperability across mixed-voltage logic domains including 1.8V, 2.5V, 3.3V, and 5V systems |
| Max tpd | 4.6ns at VCC = 3.3V, CL = 15pF - supports clean signal buffering up to ~100MHz clock/data rates |
| Output Drive | ±24mA at VCC = 3.3V - drives multiple LVC loads or moderate capacitive loads without external buffers |
| Input Tolerance | 0V to 5.5V - allows 5V signals to be safely interfaced into 3.3V or 1.8V systems |
| Hysteresis ΔVT | 0.59V typical at VCC = 3V - rejects noise up to ~600mV peak-to-peak on slow or noisy input edges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVRG4 | SOT-23-5 package (2.9mm × 1.6mm body); higher thermal resistance (RθJA = 357.1°C/W vs. 371.0°C/W) | Better suited for manual assembly or prototyping due to larger pad pitch and visibility | Choose for ease of soldering or thermal margin in low-airflow environments |
| NC7SZ17P5X | Smaller SC70-5 footprint (same pinout), but lower drive (±24mA only at VCC ≥ 4.5V); no Ioff support | Lacks Ioff and 5.5V input tolerance - unsuitable for hot-swap or mixed-voltage translation | Acceptable only in fixed 3.3V/5V systems where power sequencing is not required |
Compared with SN74LVC1G17DBVRG4 and NC7SZ17P5X, SN74LVC1G17DCKRG4 offers identical logic function and SC70-5 compatibility but adds guaranteed Ioff and 5.5V-tolerant inputs - making it the only choice for robust, mixed-voltage, hot-pluggable designs.

FAQ
What is the function of SN74LVC1G17DCKRG4?
SN74LVC1G17DCKRG4 performs a noninverting Schmitt-trigger buffer function (Y = A), converting slow or noisy input signals into clean, rail-to-rail CMOS output transitions. Its hysteresis rejects noise, and its 5.5V-tolerant inputs allow safe interfacing with higher-voltage sources. The device is fully specified for 1.65V–5.5V operation and supports partial-power-down via Ioff.
Does SN74LVC1G17DCKRG4 support hot-swap or live insertion?
Yes, SN74LVC1G17DCKRG4 supports live insertion through its Ioff feature, which disables outputs and blocks current backflow when VCC = 0V. This protects upstream and downstream circuitry during hot-plug events and enables safe partial-power-down in modular systems - confirmed in TI's datasheet Section 7.1 and Absolute Maximum Ratings table.
What is the maximum propagation delay for SN74LVC1G17DCKRG4?
The maximum propagation delay (tpd) for SN74LVC1G17DCKRG4 is 4.6ns at VCC = 3.3V with CL = 15pF and TA = 25°C (Table 5-2). Under worst-case conditions (–40°C to 125°C, CL = 50pF), tpd increases to 6.5ns - verified in Table 5-4 of the official datasheet.
Can SN74LVC1G17DCKRG4 interface 5V signals into a 3.3V system?
Yes, SN74LVC1G17DCKRG4 accepts input voltages up to 5.5V regardless of VCC level, enabling direct 5V-to-3.3V level translation without external components. This is explicitly stated in Section 7.3 ("Inputs accept voltages to 5.5V") and validated in Recommended Operating Conditions (VI = 0–5.5V).
What package type does SN74LVC1G17DCKRG4 use?
SN74LVC1G17DCKRG4 uses the SC70-5 (DCK) package: 2.0mm × 2.1mm body size, 0.65mm pitch, 5-pin configuration with GND, A, N.C., Y, and VCC terminals. This is confirmed in TI's Package Information table and Orderable Part Number Addendum for SN74LVC1G17DCKRG4.
