Product details
Overview
74LVC2G17DW-7 from Diodes Incorporated is a dual Schmitt trigger buffer IC in SOT363 package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.0V, with 5.5V-tolerant inputs and IOFF partial-power-down protection - used for noise-immune signal conditioning in mixed-voltage I/O interfaces of portable computing and consumer electronics.
For engineers reviewing the 74LVC2G17DW-7 datasheet, 74LVC2G17DW-7 pinout, 74LVC2G17DW-7 application, or 74LVC2G17DW-7 equivalent, key selection criteria include input hysteresis (min 0.15V at 1.8V), propagation delay (max 5.4ns at 5V over –40°C to +125°C), IOFF leakage (±20μA), Schmitt-trigger threshold symmetry, and SOT363 thermal resistance (371°C/W).
Technical Context
This device implements two independent non-inverting Schmitt trigger buffers with push-pull outputs, each featuring asymmetric input thresholds (VT+ = 1.30–3.60V, VT− = 0.25–2.30V at VCC = 1.8–5.5V) and ≥0.15V hysteresis to reject noise on slow-rising/falling signals. It supports mixed-voltage interfacing via 5.5V-tolerant inputs while powered from as low as 1.65V.
The IOFF circuit actively disables outputs during power-down, limiting backflow current to ±20μA when VCC = 0V and VI/VO = 5.5V - enabling safe hot-insertion and partial-power-down operation in multi-rail systems without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interface between 1.8V, 2.5V, 3.3V, and 5V logic domains |
| Input Voltage Tolerance | Up to 5.5V - allows inputs to remain functional even when unpowered or driven by higher-voltage sources |
| Output Drive Strength | ±24mA at VCC = 3.0V - sufficient to drive moderate capacitive loads (e.g., 30–50pF) with fast edge rates |
| Propagation Delay | Max 5.4ns at VCC = 5V, TA = –40°C to +125°C - ensures timing-critical signal buffering in high-speed digital subsystems |
| Hysteresis (ΔVT) | 0.15V to 1.90V depending on VCC - provides robust noise immunity against EMI and ground bounce in noisy environments |
| IOFF Leakage Current | ±20μA max at VI/VO = 5.5V, VCC = 0V - prevents damaging back-current during system power sequencing |
| ESD Protection | 2000V HBM, 1000V CDM - meets industrial-grade reliability requirements without external protection components |
Pinout & Package
SOT363 package: 2.0mm × 2.0mm × 1.1mm body, 0.65mm lead pitch, matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Buffer 1 | Non-inverting Schmitt-trigger input; accepts 0–5.5V regardless of VCC |
| GND | Ground Reference | Common return path for both buffers and internal circuitry; must be low-impedance |
| 2A | Input A of Buffer 2 | Independent non-inverting Schmitt-trigger input; electrically isolated from 1A |
| 2Y | Output Y of Buffer 2 | Push-pull CMOS output; sinks/sourcing up to ±24mA at 3.0V |
| VCC | Power Supply | Single supply rail for both buffers; powers internal logic and output stage |
| 1Y | Output Y of Buffer 1 | Push-pull CMOS output; identical drive capability and timing to 2Y |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Schmitt trigger buffers | Enables simultaneous noise-immune conditioning of two asynchronous signals (e.g., reset, interrupt, clock enable) |
| IOFF partial-power-down support | Prevents current backflow when VCC = 0V, allowing safe insertion into live backplanes or hot-swap modules |
| 5.5V-tolerant inputs | Eliminates need for external level shifters when interfacing 5V sensors or legacy peripherals to low-voltage MCUs |
| Low ICC supply current | Max 40μA over full temperature range - suitable for battery-powered applications requiring ultra-low quiescent power |
| Wide operating temperature range | –40°C to +125°C ambient - qualified for industrial and extended-temperature embedded control applications |

IC Role / Device Role / Timing Role: Bidirectionally tolerant buffer enabling clean, glitch-free propagation of sequencing signals while maintaining rail independence. Use Value: Guarantees deterministic power-up order and avoids latch-up or undefined states in multi-rail SoC subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G17DBVR | Same logic function and electrical specs; SOT23-6 package (3.0mm × 1.75mm) vs. SOT363 (2.0mm × 2.0mm); higher θJA (204°C/W) but larger pad area eases hand-soldering. | Better thermal performance in high-density layouts; less suitable for ultra-compact wearables due to larger footprint. | Select when board space permits and manual rework is required; avoid in <2.5mm² area-constrained designs. |
| 74AUP2G17GW,125 | Lower ICC (max 1μA vs. 40μA), wider VCC range (0.8–3.6V), but no 5.5V input tolerance; max output drive ±4mA at 3.0V. | Optimized for ultra-low-power always-on sensing nodes, not mixed-voltage level shifting. | Select only for battery-powered IoT endpoints where input voltage never exceeds 3.6V and drive strength <±4mA suffices. |
Compared with SN74LVC2G17DBVR, the 74LVC2G17DW-7 offers superior board-area efficiency and lower thermal resistance in dense portable designs; compared with 74AUP2G17GW,125, it trades ultra-low ICC for essential 5.5V input tolerance and 6× higher drive strength - making it the only choice for robust mixed-voltage signal conditioning.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LVC2G17DW-7?
The 74LVC2G17DW-7 is fully specified down to 1.65V per its Recommended Operating Conditions table; below this, propagation delay increases and output drive degrades - data retention remains functional at 1.5V, but logic functionality is not guaranteed.
Can the 74LVC2G17DW-7 be used to interface a 5V sensor output to a 1.8V microcontroller?
Yes: its 5.5V-tolerant inputs accept 5V signals while powered from 1.8V, and its Schmitt-trigger thresholds scale with VCC - at 1.8V supply, VT+ is 0.70–1.50V and VT− is 0.25–0.90V, ensuring clean logic-level translation without external resistors.
Does the 74LVC2G17DW-7 require external pull-up or pull-down resistors on unused inputs?
Yes: per Note 6 in the datasheet, unused inputs must be tied to VCC or GND to prevent floating nodes that increase ICC, cause oscillation, or induce ESD susceptibility - internal pull-ups/downs are not provided.
How does the IOFF feature behave during power-down sequences?
When VCC drops below ~0.2V, the IOFF circuit activates automatically, disabling both outputs and limiting leakage to ±20μA even if inputs or outputs are held at 5.5V - this prevents back-current flow into a powered-down domain and eliminates need for external blocking diodes.
