Product details
Overview
74LVC2G17FZ4-7 from Diodes Incorporated is a dual Schmitt trigger buffer IC in X2-DFN1410-6 package, operating from 1.65V to 5.5V supply, with 5.5V-tolerant inputs and ±24mA output drive at 3.0V. It supports partial power-down via IOFF circuitry and delivers hysteresis of 0.70–1.90V across voltage rails. Used for noise-immune signal conditioning in mixed-voltage I/O interfaces.
For engineers reviewing the 74LVC2G17FZ4-7 datasheet, 74LVC2G17FZ4-7 pinout, 74LVC2G17FZ4-7 application, or 74LVC2G17FZ4-7 equivalent, key selection criteria include input hysteresis width, IOFF leakage (<±20μA), propagation delay (≤5.4ns at 5V), 1.4mm × 1.0mm DFN footprint, and 5.5V input tolerance in level-shifting designs.
Technical Context
This device implements two independent non-inverting Schmitt trigger buffers with push-pull outputs. Each channel features asymmetric input thresholds (VT+ = 1.30–3.80V, VT− = 0.60–2.50V at VCC = 3.0–5.5V) yielding programmable noise immunity. The IOFF circuit actively disables outputs during power-down to prevent back-current flow.
It operates across industrial temperature range (−40°C to +125°C) with guaranteed switching performance under 30pF/50pF loads. Input capacitance is 3.5pF typical; power dissipation capacitance is 20pF at 3.3V/10MHz. No internal pull-ups or pull-downs - unused inputs must be tied to VCC or GND per datasheet guidance.
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 safe connection to higher-voltage signals without external clamping |
| Hysteresis (ΔVT) | 0.70V to 1.90V - rejects noise up to ±0.95V on slow-rising/falling waveforms |
| Output Drive Strength | ±24mA at VCC = 3.0V - drives standard CMOS loads and short PCB traces without buffering |
| Propagation Delay (tPD) | ≤5.4ns at VCC = 5V, CL = 50pF - supports >100MHz signal edge rates in timing-critical paths |
| IOFF Leakage Current | ±20μA max at TA = +125°C - prevents damaging backflow when VCC = 0V while inputs remain active |
| ESD Robustness | 2000V HBM, 1000V CDM - withstands handling and board-level ESD events without latch-up |
Pinout & Package
X2-DFN1410-6 is a 1.4mm × 1.0mm × 0.4mm leadless, RoHS-compliant surface-mount package with 0.5mm pad pitch and NiPdAu terminal finish. Pin 1 identifier is marked by a chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input A | Schmitt-triggered input for first buffer channel; accepts 0–5.5V regardless of VCC |
| GND | Ground | Reference node for all inputs, outputs, and internal circuitry; requires low-inductance PCB connection |
| 2A | Data Input B | Schmitt-triggered input for second buffer channel; electrically isolated from 1A |
| 2Y | Data Output B | Push-pull output driven by 2A; sinks/sourcing up to ±24mA at 3.0V |
| VCC | Supply Voltage | Power rail for internal logic and output drivers; bypassing with 100nF ceramic capacitor required |
| 1Y | Data Output A | Push-pull output driven by 1A; fully specified for simultaneous switching with 2Y |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Schmitt triggers | Enables noise-immune conditioning of two asynchronous signals (e.g., reset, interrupt, clock enable) |
| IOFF partial power-down support | Prevents current backflow from live inputs to unpowered VCC/GND rails - critical for hot-swap and power-gating systems |
| 5.5V-tolerant inputs on 1.65–5.5V supply | Eliminates need for external level shifters when interfacing legacy 5V peripherals to modern low-voltage MCUs |
| Low ICC (≤40μA) | Reduces quiescent power in battery-backed or always-on monitoring circuits without sacrificing speed |
| Small-footprint X2-DFN1410-6 package | 1.4mm × 1.0mm area saves PCB space in compact consumer electronics and portable devices |
Applications
| USB Type-C Port Detection | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Detecting CC pin voltage polarity and level to determine USB host/device role and cable orientation. IC Role / Device Role / Timing Role: Dual Schmitt buffer conditions noisy analog comparator outputs before MCU GPIO sampling. Use Value: Hysteresis rejects EMI-induced glitches on long flex cables; 5.5V tolerance accommodates VBUS-sensed CC voltages up to 5.25V. |
Use Scenario: Conditioning slow-rising thermistor or potentiometer wiper signals in PLC analog input modules. IC Role / Device Role / Timing Role: Converts analog threshold crossings into clean digital edges for microcontroller edge-triggered interrupts. Use Value: Adjustable VT+/VT− ensures reliable detection despite sensor drift; IOFF prevents backfeed during module hot-swap maintenance. |
| Mobile Device Power Sequencing | Automotive Infotainment I/O Isolation |
|
Use Scenario: Synchronizing power-on reset assertion across multiple SoC voltage rails with varying ramp times. IC Role / Device Role / Timing Role: Buffers delayed enable signals from sequencer ICs to ensure monotonic, glitch-free reset deassertion. Use Value: Low tPD (≤5.4ns) preserves timing margins; 1.65V operation supports ultra-low-power auxiliary domains. |
Use Scenario: Isolating CAN transceiver standby control lines from infotainment head unit MCU during sleep mode. IC Role / Device Role / Timing Role: Schmitt buffer gates wake-up request signals while blocking noise from 12V battery line coupling. Use Value: IOFF blocks reverse current when head unit VCC is off but CAN bus remains live; 125°C rating meets automotive under-hood requirements. |
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 | SOT-23-6 package (2.9mm × 2.8mm); higher θJA (204°C/W); same electrical specs | Less suitable for space-constrained mobile designs; better thermal relief on low-layer boards | Select when manual rework or legacy footprint compatibility is required over miniaturization |
| 74LVC2G17FW4-7 | X2-DFN1010-6 package (1.0mm × 1.0mm); 0.35mm pad pitch; identical logic and IOFF behavior | Higher assembly yield risk on fine-pitch stencil printing; tighter layout constraints | Choose only if board real estate is more constrained than assembly capability allows |
Compared with SN74LVC2G17DBVR and 74LVC2G17FW4-7, the 74LVC2G17FZ4-7 offers optimal balance of miniaturization (1.4mm × 1.0mm), manufacturability (0.5mm pitch), and thermal performance (θJA = 430°C/W), making it preferred for high-density portable electronics where both size and process robustness matter.

FAQ
Can 74LVC2G17FZ4-7 be used with a 1.2V supply?
No. The absolute minimum recommended supply voltage is 1.65V per DS35164 Rev 12-2. At 1.2V, the device fails to meet VOH/VOL specifications, input thresholds become undefined, and IOFF functionality is not guaranteed. For 1.2V systems, consider the ALVC or AUP logic families instead.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies switching characteristics up to 50pF load capacitance with guaranteed tPD ≤5.4ns at 5V. Driving >50pF increases propagation delay nonlinearly and may cause output ringing; for >100pF loads, add series termination or use a dedicated buffer with higher drive strength.
Does the X2-DFN1410-6 package require special PCB layout considerations?
Yes. Use the manufacturer-recommended pad layout (C = 1.000mm, G = 0.200mm, X = 0.400mm, Y = 0.150mm) and expose thermal pad (if present) to inner ground plane via ≥4 vias. Avoid solder mask defined pads; specify NSMD for reliable reflow and void minimization.
Is 74LVC2G17FZ4-7 qualified for automotive applications?
As shipped, it is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., 74LVC2G17FZ4Q-7) with PPAP documentation, extended temperature screening (−40°C to +125°C), and IATF 16949 manufacturing - contact Diodes sales for qualification status and part numbering.
