Product details
Overview
SN74LVC3G17YZPR from Texas Instruments is a triple Schmitt-trigger buffer IC operating from 1.65 V to 5.5 V, performing Y = A logic with hysteresis (ΔVT = 0.56–1.11 V), 5.4 ns max tpd at 3.3 V, ±24-mA output drive, and Ioff-enabled live insertion support. It serves signal conditioning and noise-immune level translation in portable audio and SSD power sequencing.
For engineers reviewing the SN74LVC3G17YZPR datasheet, SN74LVC3G17YZPR pinout, SN74LVC3G17YZPR application, or SN74LVC3G17YZPR equivalent, this page delivers verified package mapping (DSBGA-8), confirmed Schmitt thresholds (VT+ = 1.5–3.33 V, VT– = 0.39–2.29 V), Ioff behavior at 0 V supply, and NanoFree™ die-size packaging constraints for high-density layout.
Technical Context
This device implements three independent noninverting buffers with Schmitt-trigger inputs-each exhibiting distinct VT+ and VT– thresholds to reject slow or noisy signals. Its Ioff circuitry actively disables outputs during partial power-down, blocking reverse current flow when VCC = 0 V.
The DSBGA-8 (YZP) package uses wafer-level chip-scale construction (1.91 mm × 0.91 mm), enabling direct die mounting without wire bonds or leadframes. All inputs tolerate up to 5.5 V regardless of VCC, supporting mixed-voltage interfacing between 1.8-V, 3.3-V, and 5-V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic families |
| Max Propagation Delay | 5.4 ns at VCC = 3.3 V, CL = 30/50 pF - Supports >100-MHz signal conditioning in timing-critical paths |
| Input Threshold Hysteresis | 0.56 V to 1.11 V - Rejects noise up to ~1 V peak-to-peak on slow-rising/falling signals |
| Output Drive Strength | ±24 mA at VCC = 3.3 V - Sinks/sours sufficient current to directly drive LEDs, small MOSFET gates, or multiple CMOS loads |
| Ioff Current | ±10 μA max at VI/VO = 5.5 V, VCC = 0 V - Prevents back-drive damage during hot-swap or partial-power-down sequences |
| ESD Rating | 2000-V HBM, 1000-V CDM - Meets industrial-grade ESD robustness per JESD22 without external protection |
| Operating Temperature | –40°C to +85°C - Qualified for consumer and industrial ambient environments (per YZP package spec) |
Pinout & Package
SN74LVC3G17YZPR uses an 8-pin DSBGA (Die Size Ball Grid Array) package measuring 1.91 mm × 0.91 mm with 0.5-mm ball pitch. The bottom-side ball layout follows standard NanoFree™ orientation with Pin 1 located at quadrant Q1 (top-left when viewed from component side).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input 1 | Noninverting Schmitt input for Buffer 1; accepts 0–5.5 V regardless of VCC |
| 1Y | Output 1 | Noninverting buffered output; drives ±24 mA at 3.3 V with rail-to-rail swing |
| 2A | Input 2 | Noninverting Schmitt input for Buffer 2; electrically isolated from other channels |
| 2Y | Output 2 | Noninverting buffered output; supports independent load switching |
| 3A | Input 3 | Noninverting Schmitt input for Buffer 3; requires tie-high/tie-low if unused |
| 3Y | Output 3 | Noninverting buffered output; disabled by Ioff when VCC = 0 V |
| GND | Ground | Reference node for all inputs/outputs; must be low-impedance for VOLP/VOHV control |
| VCC | Power Supply | Single supply rail (1.65–5.5 V); bypass capacitor required within 2 mm of ball |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.56–1.11 V hysteresis to eliminate chatter on slow or noisy signals such as mechanical switch debouncing or analog sensor outputs |
| Ioff partial-power-down | Disables all outputs and blocks reverse current when VCC = 0 V - enables safe live insertion into powered backplanes |
| NanoFree™ DSBGA-8 | 1.91 mm × 0.91 mm footprint with no leads or mold compound - reduces board area by >70% vs. SSOP/VSSOP alternatives |
| 5.5-V tolerant inputs | Accepts input voltages up to 5.5 V independent of VCC - simplifies level-shifting between 1.8-V microcontrollers and 5-V peripherals |
| Low ICC | 10 μA maximum quiescent current - extends battery life in always-on portable devices like wireless headsets and tablets |
Applications
| Audio Dock Signal Conditioning | SSD Power Sequencing Control |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17YZPR | Single-channel version in same DSBGA-5 package; identical VCC range, thresholds, and Ioff behavior | Lacks two additional buffers - suitable only when one Schmitt channel is needed | Select when board space allows smaller 5-ball footprint and system requires only one buffered path |
| SN74LV3G17YZPR | Same pinout but LV-family: lower VT+ (1.2–2.4 V) and VT– (0.6–1.5 V); 3.3-V max VCC; no 5.5-V input tolerance | Not compatible with 5-V interface domains; reduced noise margin at 3.3 V | Choose only for cost-sensitive 3.3-V-only systems where 5-V tolerance is unnecessary |
Compared with SN74LVC3G17YZPR, SN74LVC1G17YZPR saves 38% board area but requires three discrete units for triple functionality, while SN74LV3G17YZPR cuts cost but forfeits 5-V input compatibility and wide VCC flexibility - making SN74LVC3G17YZPR optimal for compact, mixed-voltage, noise-prone portable designs.

FAQ
What is the operating temperature range for SN74LVC3G17YZPR?
The SN74LVC3G17YZPR is specified for operation from –40°C to +85°C, matching the thermal qualification of its DSBGA (YZP) package variant. This range supports deployment in consumer portable devices and industrial edge nodes where ambient conditions exceed commercial-grade limits. The full –40°C to +125°C range applies to SSOP and VSSOP variants, but not to the YZP marking.
Does SN74LVC3G17YZPR support 5-V input signals while powered from 1.8 V?
Yes, SN74LVC3G17YZPR supports input voltages up to 5.5 V regardless of VCC level - including when VCC = 1.8 V. This 5-V tolerance enables direct interfacing with legacy 5-V peripherals or mixed-signal sensors without external level shifters, preserving signal integrity and reducing BOM count.
How does the Ioff feature function in SN74LVC3G17YZPR during power-down?
In SN74LVC3G17YZPR, the Ioff circuitry automatically disables all three outputs and presents high-impedance states when VCC = 0 V, preventing damaging current backflow from live system buses into the unpowered IC. This behavior is verified across –40°C to +85°C and supports hot-plug compliance in modular electronics.
What is the typical output ground bounce (VOLP) for SN74LVC3G17YZPR?
The typical output ground bounce (VOLP) for SN74LVC3G17YZPR is <0.8 V at VCC = 3.3 V and TA = 25°C, measured under switching conditions with CL = 30/50 pF. This low VOLP value reflects optimized output stage design and ensures stable logic-low referencing during fast transitions in dense PCB layouts.
Can unused inputs on SN74LVC3G17YZPR be left floating?
No - all unused inputs on SN74LVC3G17YZPR must be tied to either VCC or GND to prevent undefined logic states and excessive ICC. Floating CMOS inputs risk oscillation, increased power consumption, and potential latch-up. TI recommends tying unused Schmitt inputs to VCC for predictable high-output behavior or to GND for low-output behavior.
