Product details
Overview
SN74LVC3G17YEPR from Texas Instruments is a triple Schmitt-trigger buffer IC operating from 1.65 V to 5.5 V, performing Y = A logic with independent channels, featuring ±24-mA output drive at 3.3 V, 5.4 ns max propagation delay, and Ioff support for live insertion in partial-power-down systems. It is used in audio docks, SSDs, and portable tablets for noise-immune signal conditioning.
For engineers reviewing the SN74LVC3G17YEPR datasheet, SN74LVC3G17YEPR pinout, SN74LVC3G17YEPR application, or SN74LVC3G17YEPR equivalent, key selection factors include its hysteresis (0.56–1.11 V), overvoltage-tolerant inputs (up to 5.5 V), NanoFree™ DSBGA-8 package, and guaranteed operation from –40°C to 85°C.
Technical Context
The SN74LVC3G17YEPR implements three noninverting Schmitt-trigger buffers with distinct VT+ (1.5–3.33 V) and VT– (0.39–2.29 V) thresholds, enabling robust noise rejection on slow or noisy input signals. Its Ioff circuitry actively disables outputs during power-down, blocking back-current flow and supporting hot-plug capability.
Designed in NanoFree™ DSBGA-8 packaging, the device uses the silicon die as the package body (1.91 mm × 0.91 mm), eliminating bond wires and mold compound to minimize parasitic inductance and capacitance-critical for high-speed digital integrity in space-constrained portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports single-supply operation across legacy 3.3 V and modern low-voltage 1.8 V/2.5 V systems |
| Max Propagation Delay | 5.4 ns at 3.3 V, CL = 30/50 pF - enables timing-critical signal buffering in high-speed consumer interfaces |
| Hysteresis (ΔVT) | 0.56 V (min) to 1.11 V (max) - provides noise immunity against EMI and ground bounce in noisy PCB environments |
| Output Drive | ±24 mA at 3.3 V - sufficient to directly drive multiple LVC inputs or small capacitive loads without external buffers |
| Ioff Current | ±10 μA max - ensures safe isolation during partial power-down, preventing back-drive damage in mixed-rail systems |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - allows interfacing with higher-voltage peripherals without level shifters |
| Operating Temperature | –40°C to +85°C - qualified for commercial and extended-temperature portable electronics applications |

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; lacks two additional buffers and shared VCC/GND efficiency | Suitable only when exactly one Schmitt buffer is needed; no channel-to-channel timing correlation | Select when board area is critical and multi-channel synchronization is unnecessary |
| SN74LV3G17DCUR | VSSOP-8 package (2.30 mm × 2.00 mm); higher thermal resistance (227°C/W vs. 102°C/W); identical electrical specs | Better suited for prototyping or manual assembly due to larger pitch; less optimal for ultra-thin production designs | Prefer for development boards or cost-sensitive non-portable applications where DSBGA rework is impractical |
Compared with SN74LVC3G17YEPR, SN74LVC1G17YZPR saves area but sacrifices channel count and integration density, while SN74LV3G17DCUR offers easier assembly at the expense of thermal performance and footprint size-making SN74LVC3G17YEPR optimal for volume-manufactured portable electronics requiring miniaturization and noise resilience.

FAQ
What is the maximum operating temperature range for the SN74LVC3G17YEPR?
The SN74LVC3G17YEPR is specified for operation from –40°C to +85°C. This range is validated per JEDEC JESD78 latch-up testing and supported by thermal characterization data showing RθJA = 102°C/W in its DSBGA-8 package. The device maintains full electrical performance-including hysteresis and propagation delay-across this entire range, making it suitable for consumer portable applications exposed to ambient thermal cycling.
Does the SN74LVC3G17YEPR support 5-V input signals when powered from 1.8 V?
Yes, the SN74LVC3G17YEPR supports input voltages up to 5.5 V regardless of VCC level, including when VCC = 1.8 V. This overvoltage tolerance is explicitly guaranteed in the datasheet's Recommended Operating Conditions table and enables direct interfacing with 5-V peripherals without external level shifters-reducing BOM count and signal path complexity in mixed-voltage systems.
How does the Ioff feature function in the SN74LVC3G17YEPR during power-down?
The Ioff feature in the SN74LVC3G17YEPR actively disables all three outputs when VCC = 0 V, limiting leakage current to ±10 μA maximum. This prevents damaging back-current flow from live system buses into the unpowered IC, enabling safe live insertion and partial-power-down modes. The function is intrinsic to the device's design and requires no external control signals or configuration.
What is the typical hysteresis voltage (ΔVT) of the SN74LVC3G17YEPR at 3.3 V supply?
At VCC = 3.3 V, the SN74LVC3G17YEPR exhibits a typical hysteresis voltage (ΔVT = VT+ – VT–) of 0.87 V, with a minimum of 0.56 V across temperature. This value is derived from the datasheet's Electrical Characteristics table (VT+ = 1.87 V typ, VT– = 1.14 V typ), and provides robust noise margin against ground bounce and EMI in high-density portable PCB layouts.
Can unused inputs on the SN74LVC3G17YEPR be left floating?
No, unused inputs on the SN74LVC3G17YEPR must be tied to either VCC or GND. Floating inputs can cause undefined output states, increased ICC, and potential oscillation due to the Schmitt-trigger's sensitivity to intermediate voltages. TI's application note SCBA004 explicitly mandates biasing all unused CMOS inputs-this applies to all three A-inputs (1A, 2A, 3A) on the SN74LVC3G17YEPR.
