Product details
Overview
SN74LVC2G17YZAR from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65-V to 5.5-V VCC operation, performing Y = A logic with hysteresis thresholds (VT+ = 2.2 V, VT– = 1.3 V at 3 V), 5.4 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for partial-power-down mode. It is used in noise-prone signal conditioning paths in industrial sensor interfaces and low-voltage portable logic systems.
For engineers reviewing the SN74LVC2G17YZAR datasheet, SN74LVC2G17YZAR pinout, SN74LVC2G17YZAR application, or SN74LVC2G17YZAR equivalent, key selection criteria include Schmitt-trigger hysteresis width (0.4–1.1 V), WCSP package thermal impedance (143°C/W), Pb-free NanoFree™ DSBGA footprint, and compatibility with mixed-voltage I/O up to 5.5 V.
Technical Context
This device implements two independent noninverting buffers with Schmitt-trigger inputs-each channel provides distinct positive-going (VT+) and negative-going (VT–) input thresholds to reject noise on slow or noisy signals. Hysteresis (∆VT = 0.4–1.4 V across VCC range) enables reliable level detection in environments with EMI or signal ringing.
It features Ioff circuitry that disables outputs during power-down, preventing backflow current when VCC = 0 V while inputs remain biased at 5.5 V. The NanoFree™ WCSP (YZA) package uses die-as-package construction with 0.17-mm solder bumps, requiring no wire bonds or leadframe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - supports direct interfacing with 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without level shifters |
| Max tpd | 5.4 ns at 3.3 V - enables use in sub-200-MHz digital timing paths with margin for board trace delays |
| Output Drive | ±24 mA at 3.3 V - sufficient to drive 50-Ω transmission lines or fan-out to ≥10 LVC loads |
| Hysteresis ∆VT | 0.4 V to 1.1 V - rejects noise spikes up to 1.1 V peak-to-peak on input signals without false triggering |
| Ioff Current | ±10 µA max - ensures safe isolation during hot-insertion or partial system power-down sequences |
| Input Voltage Range | –0.5 V to 5.5 V - allows 5-V-tolerant inputs even when VCC = 1.65 V, simplifying mixed-supply designs |
| ICC Max | 10 µA - enables integration into battery-powered systems with multi-year standby life |
Pinout & Package
NanoFree™ WCSP (YZA) package: 6-bump, 0.17-mm Pb-free solder bump array, 1.0 mm × 1.4 mm body, 0.5-mm pitch, bottom-side marking "YZA" with pin-1 indicator (• = Pb-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Channel 1 input | Schmitt-trigger input with VT+ = 2.2 V / VT– = 1.3 V at VCC = 3 V; accepts up to 5.5 V |
| GND | Ground reference | Common return for both channels; must be low-impedance to minimize ground bounce (VOLP < 0.8 V) |
| 2A | Channel 2 input | Independent Schmitt input; identical threshold behavior to 1A; no crosstalk between channels |
| 1Y | Channel 1 output | Noninverting buffered output with VOH ≥ 2.3 V / VOL ≤ 0.55 V at 24-mA load and 3 V VCC |
| VCC | Supply voltage | Single supply for both channels; powers internal logic and output drivers; decoupling required within 2 mm |
| 2Y | Channel 2 output | Independent noninverting output; supports simultaneous switching with 1Y without violating ICC limits |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean signal restoration of slow-rising or noisy waveforms (e.g., mechanical switch debouncing, sensor outputs) |
| Ioff partial-power-down | Prevents back-current flow when VCC = 0 V but inputs are pulled to 5.5 V - critical for hot-swap and modular subsystems |
| NanoFree™ WCSP packaging | Eliminates package parasitics (Cpd = 19 pF at 3.3 V); reduces board area by >70% vs. SOT-23; enables ultra-thin wearable designs |
| 5.5-V tolerant inputs | Allows direct connection to legacy 5-V microcontrollers or sensors without external level translators |
| Low ICC (10 µA max) | Supports always-on monitoring circuits in energy-harvesting or coin-cell-powered IoT endpoints |

FAQ
What is the pin-1 identifier for SN74LVC2G17YZAR?
The SN74LVC2G17YZAR uses a bottom-side marking convention where pin 1 is indicated by a • (dot) on the solder bump array, denoting Pb-free composition. This matches the YZA package specification per TI's ordering information table and is visible under optical inspection or X-ray.
Does SN74LVC2G17YZAR support 5-V input signals when powered at 1.8 V?
Yes, SN74LVC2G17YZAR supports input voltages up to 5.5 V regardless of VCC level (1.65 V to 5.5 V). When VCC = 1.8 V, the inputs remain 5-V tolerant, enabling direct interface with legacy 5-V peripherals without level-shifting circuitry.
What is the maximum output current capability of SN74LVC2G17YZAR at 3.3 V?
At VCC = 3.3 V, SN74LVC2G17YZAR delivers ±24 mA per output (IOL = 24 mA, IOH = –24 mA), verified in the Electrical Characteristics table. This allows driving moderate capacitive loads or multiple downstream LVC inputs without signal degradation.
How does the Ioff feature function in SN74LVC2G17YZAR during system power-down?
The Ioff circuitry in SN74LVC2G17YZAR actively disables both outputs when VCC = 0 V, limiting input/output leakage to ±10 µA even if external signals remain at 5.5 V. This prevents damaging back-current flow into a powered-down domain, supporting safe partial-power-down architectures.
Is SN74LVC2G17YZAR RoHS-compliant and what is its moisture sensitivity level?
Yes, SN74LVC2G17YZAR is RoHS-compliant with Green (RoHS & no Sb/Br) eco plan and SnAgCu (SNAGCU) lead finish. Its MSL rating is Level-1-260°C-UNLIM, meaning it has unlimited floor life and requires no baking prior to reflow soldering.
