Product details
Overview
SN74LVC1G17YZTR from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in noise-prone 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 mixed-voltage systems such as USB peripheral buffers and SSD power sequencing.
For engineers reviewing the SN74LVC1G17YZTR datasheet, SN74LVC1G17YZTR pinout, SN74LVC1G17YZTR application, or SN74LVC1G17YZTR equivalent, key selection criteria include its ultra-small X2SON (DPW) 5-pin package (0.8mm × 0.8mm), Ioff support for live insertion, Schmitt-trigger hysteresis (0.64V typ at 3V), and guaranteed operation across –40°C to 125°C.
Technical Context
The SN74LVC1G17YZTR 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 ICC (≤10μA) while supporting rail-to-rail output swing and 5.5V input tolerance independent of VCC.
It integrates Ioff circuitry that disables outputs when VCC = 0V, preventing back-drive current and enabling partial-power-down operation. The device meets JESD78 Class II latch-up immunity (>100mA) and exceeds JEDEC ESD ratings: ±2000V HBM, ±200V MM, ±1000V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - enables robust level translation without external clamping |
| tpd Max | 4.6ns at VCC = 3.3V, CL = 15pF - suitable for ≤100MHz signal buffering |

Pinout & Package
SN74LVC1G17YZTR is packaged in a 5-terminal X2SON (DPW) package measuring 0.8mm × 0.8mm with 0.5mm pitch, optimized for space-constrained portable and embedded applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No internal connection (N.C.) | Unused pad; must be left floating or grounded per layout guidelines - no electrical function |
| 2 | Input (A) | Schmitt-trigger input accepting 0–5.5V; threshold hysteresis enables noise immunity on slow edges |
| 3 | GND | Digital ground reference; requires low-inductance connection to PCB ground plane |
| 4 | Output (Y) | Noninverting buffered output with rail-to-rail swing and ±24mA drive capability |
| 5 | VCC | Power supply input (1.65–5.5V); requires local 0.1μF bypass capacitor placed adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small DPW package | 0.64mm² footprint (0.8mm × 0.8mm) saves >70% board area vs. SOT-23, ideal for wearables and SSD modules |
| Schmitt-trigger input | 0.59V typical hysteresis at 3V eliminates false triggering from EMI or slow RC edges in audio dock interfaces |
| Ioff protection | Enables safe live insertion into powered-backplane systems by disabling outputs when VCC = 0V |
| 5.5V-tolerant inputs | Accepts 5V signals while operating at 1.8V/2.5V/3.3V - simplifies voltage translation in mixed-supply AV receivers |

FAQ
What is the maximum operating temperature for SN74LVC1G17YZTR?
The SN74LVC1G17YZTR is fully specified from –40°C to +125°C ambient temperature. This extended range is validated per JEDEC JESD22-A108 and supports deployment in under-hood automotive modules, industrial SSDs, and high-density AV receivers where thermal margins are critical. All electrical parameters-including tpd, hysteresis, and Ioff-are guaranteed across this full range.
Does SN74LVC1G17YZTR support level translation between 5V and 3.3V systems?
Yes, SN74LVC1G17YZTR supports down-translation: its inputs tolerate up to 5.5V regardless of VCC voltage (1.65–5.5V), allowing a 5V signal to safely drive the A input while VCC is set to 3.3V. The Y output swings rail-to-rail (0V to 3.3V), providing clean 3.3V logic levels. No external resistors or clamps are needed.
What is the purpose of the N.C. pin on SN74LVC1G17YZTR?
Pin 1 of SN74LVC1G17YZTR is designated N.C. (No internal connection). It is an unused die pad with no electrical function. TI recommends leaving it unconnected or connecting it to GND for mechanical stability-never to VCC or signal nets. This pin does not affect device operation or thermal performance.
How does the Schmitt-trigger action improve noise immunity in SN74LVC1G17YZTR?
SN74LVC1G17YZTR uses distinct input thresholds: VT+ = 1.48V and VT– = 0.89V at VCC = 3V, creating 0.59V hysteresis. This prevents multiple toggles when input signals cross the threshold slowly or with superimposed noise-critical for debouncing buttons, cleaning up RC-filtered sensor outputs, or stabilizing long-trace GPIOs in MP3 players and PDAs.
Is SN74LVC1G17YZTR compatible with standard reflow soldering processes?
Yes, SN74LVC1G17YZTR is rated MSL Level-1 (260°C peak reflow), meaning it can undergo unlimited floor life and standard Pb-free reflow profiles without baking. Its X2SON (DPW) package has been qualified per J-STD-020, and TI provides detailed thermal profiles and stencil recommendations in the package mechanical drawing SCYU003.
