Product details
Overview
SN74LVC1G17YZVR 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, and 5.5V-tolerant inputs - used in noise-immune signal conditioning for portable audio and display interfaces.
For engineers reviewing the SN74LVC1G17YZVR datasheet, SN74LVC1G17YZVR pinout, SN74LVC1G17YZVR application, or SN74LVC1G17YZVR equivalent, key selection criteria include hysteresis voltage (ΔVT = 0.64V typ at 3V), Ioff support for live insertion, ultra-small DSBGA-4 (YZV) package with 1.25mm × 1.25mm body, and guaranteed operation from –40°C to 125°C.
Technical Context
The SN74LVC1G17YZVR implements a noninverting Schmitt-trigger buffer (Y = A) with asymmetric input thresholds: VT+ = 1.92V and VT– = 1.2V at VCC = 3V, yielding 0.72V hysteresis. This enables reliable signal restoration of slow-rising or noisy digital inputs without external components.
It features Ioff circuitry that disables outputs and isolates inputs/outputs when VCC = 0V, supporting partial-power-down modes and back-drive protection. The device operates across 1.65V–5.5V VCC while maintaining ±24mA drive capability and 10μA max ICC at 3.3V.
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-core supplies |
| Input Voltage Tolerance | Up to 5.5V - allows direct connection to 5V buses without level-shifting circuitry |
| tpd (Max) | 4.6ns at VCC = 3.3V, CL = 15pF - enables reliable operation in ≤100MHz signal paths |
| Output Drive | ±24mA at VCC = 3.3V - sufficient to drive multiple CMOS loads or light capacitive traces |
| Hysteresis (ΔVT) | 0.64V typical at VCC = 3V - rejects noise up to ~640mV peak-to-peak on input signals |
| Ioff Current | ±10μA max - prevents damaging current flow during hot-insertion or power sequencing |
| Operating Temp | –40°C to +125°C - qualified for automotive infotainment and industrial SSD controller environments |
Pinout & Package
SN74LVC1G17YZVR uses the YZV package: 4-ball DSBGA with 0.4mm pitch, 1.25mm × 1.25mm body size, and bottom-side solder balls. It is a space-optimized variant of the SN74LVC1G17 family optimized for ultra-thin portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Input | Single Schmitt-trigger input; accepts 0–5.5V regardless of VCC; must be tied high/low if unused |
| GND | Ground | Reference return path for all internal circuitry and output drivers; requires low-inductance PCB connection |
| Y | Output | Noninverting buffered output; drives ±24mA; exhibits hysteresis-based noise rejection |
| VCC | Power terminal | Supply rail (1.65–5.5V); requires local 0.1μF ceramic bypass capacitor placed adjacent to ball |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | VT+ = 1.92V / VT– = 1.2V at 3V - eliminates chatter on slow or noisy signals without external RC networks |
| Ioff support | Active at VCC = 0V - enables safe hot-plug operation and prevents back-driving in powered-down subsystems |
| 5.5V-tolerant inputs | VI max = 5.5V independent of VCC - simplifies interface to legacy 5V peripherals in 3.3V or 1.8V systems |
| Ultra-small YZV package | 1.25mm × 1.25mm, 4-ball DSBGA - reduces PCB area by >70% vs. SOT-23, ideal for space-constrained wearables and tablets |
| ESD robustness | ±2000V HBM, ±1000V CDM - meets stringent manufacturing and end-equipment reliability requirements |

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 × 1.6mm body); 5-pin layout with NC pin; higher thermal resistance (RθJA = 357°C/W) | Better suited for prototyping and manual assembly; less optimal for ultra-dense layouts requiring minimal footprint | Choose DBVR for breadboarding or when board real estate is not constrained and hand-soldering is required. |
| NC7SZ17P5X | SC-70-5 package (2.0mm × 1.25mm); 3.6V max VCC; no Ioff; 5V input tolerance not specified | Limited to ≤3.6V systems; lacks live-insertion support; lower drive (±24mA only at VCC ≥ 3V) | Choose NC7SZ17P5X only in cost-sensitive, single-supply ≤3.3V consumer applications where Ioff is unnecessary. |

FAQ
What is the function of SN74LVC1G17YZVR?
The SN74LVC1G17YZVR is a single noninverting Schmitt-trigger buffer performing Y = A. Its hysteresis (VT+ = 1.92V, VT– = 1.2V at 3V) cleans slow or noisy digital signals without external components. It operates from 1.65V to 5.5V, supports 5.5V-tolerant inputs, and features Ioff for partial-power-down use. The SN74LVC1G17YZVR is specifically packaged in a 1.25mm × 1.25mm DSBGA-4 (YZV) variant.
Does SN74LVC1G17YZVR support hot-plug operation?
Yes, SN74LVC1G17YZVR supports hot-plug via its Ioff feature: when VCC = 0V, input and output terminals are high-impedance and leakage is limited to ±10μA, preventing back-drive current into powered-down sections. This is validated per JESD78 Class II latch-up and JEDEC JESD22-C101 CDM testing. The SN74LVC1G17YZVR is explicitly rated for live insertion in systems with staggered power sequencing.
What is the maximum operating frequency for SN74LVC1G17YZVR?
The SN74LVC1G17YZVR has no defined maximum clock frequency, but its 4.6ns max propagation delay (at VCC = 3.3V, CL = 15pF) supports reliable signal conditioning up to ~100MHz in well-terminated paths. At higher frequencies or heavier loads, edge fidelity depends on trace impedance and capacitive loading - the SN74LVC1G17YZVR's ±24mA drive helps maintain rise/fall times under 15pF load, though system-level signal integrity validation remains essential.
Can SN74LVC1G17YZVR translate 5V logic to 1.8V systems?
Yes, SN74LVC1G17YZVR accepts 5.5V inputs regardless of VCC, enabling robust 5V-to-lower-voltage translation. When VCC = 1.8V, it outputs VOH ≈ 1.7V and VOL ≈ 0.1V (per DC specs), compatible with 1.8V logic thresholds. However, output drive is reduced (±4mA at 1.8V), so fanout and trace capacitance must be limited. The SN74LVC1G17YZVR's hysteresis also improves noise margin in such mixed-voltage interfaces.
What package type is SN74LVC1G17YZVR supplied in?
SN74LVC1G17YZVR is supplied in the YZV package: a 4-ball, 0.4mm-pitch DSBGA with 1.25mm × 1.25mm body size and bottom-side solder balls. It is distinct from other variants like DBV (SOT-23-5) or DCK (SC-70-5). The YZV package is optimized for ultra-thin, high-density applications including wearables and tablet SSD modules - the SN74LVC1G17YZVR leverages this for minimal PCB footprint and thermal performance.
