Product details
Overview
74LVC1G17SE-7 from Diodes Incorporated is a single 1-input Schmitt-trigger buffer with push-pull output, designed for voltage level shifting and noise-immune signal conditioning in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, supports partial power-down via IOFF, and delivers ±24mA drive at 3.3V - used in notebook I/O buffering and USB interface signal cleanup.
For engineers reviewing the 74LVC1G17SE-7 datasheet, 74LVC1G17SE-7 pinout, 74LVC1G17SE-7 application, or 74LVC1G17SE-7 equivalent, key selection criteria include input hysteresis (min 0.30V at 1.65V), propagation delay (max 4.6ns at 3.3V/15pF), IOFF leakage (±10μA), 5.5V-tolerant inputs, and SOT353 package thermal resistance (371°C/W).
Technical Context
This device implements a non-inverting Schmitt-trigger function (Y = A) with asymmetric input thresholds: VT+ ranges from 0.70V (1.65V VCC) to 3.33V (5.5V VCC); VT− ranges from 0.30V to 2.35V. Hysteresis ΔVT is guaranteed ≥0.30V across the full supply range, enabling reliable noise rejection on slow or noisy signals.
Its IOFF circuit actively disables output during power-down, blocking current backflow when VCC = 0V while inputs or outputs remain biased up to 5.5V. The CMOS design ensures low ICC (≤10μA) and supports operation from −40°C to +125°C ambient, with switching performance validated at CL = 15pF, 30pF, and 50pF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct interfacing between 1.8V, 2.5V, 3.3V, and 5V logic domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - allows connection to higher-voltage buses while powered from lower VCC, critical for mixed-supply isolation. |
| IOFF Leakage Current | ±10μA max - prevents damaging back-current flow during partial power-down, protecting upstream drivers and downstream loads. |
| Output Drive Strength | ±24mA at VCC = 3.3V - sufficient to drive 50pF loads with <7ns propagation delay, supporting high-speed GPIO and reset line buffering. |
| Hysteresis (ΔVT) | Min 0.30V at 1.65V VCC - provides robust noise immunity against EMI and ground bounce in industrial and portable applications. |
| Propagation Delay (tPD) | Max 4.6ns at VCC = 3.3V, CL = 15pF - ensures timing-critical signal conditioning without introducing excessive latency in clock or control paths. |
| ESD Protection | 2kV HBM, 1kV CDM - exceeds JEDEC standards for handling and board-level reliability in automated assembly and end-use environments. |
Pinout & Package
SOT353 (SC-70-5) package: 1.2mm × 2.1mm × 0.95mm body, 5-pin surface-mount, moisture sensitivity level 1, tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | 5.5V-tolerant Schmitt-trigger input; accepts slow-rising/falling signals and rejects noise within hysteresis window. |
| 2 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-impedance to maintain noise immunity and output integrity. |
| 3 (Y) | Data Output | Push-pull CMOS output capable of sourcing/sinking ±24mA; no external pull-up required for active-high logic functions. |
| 4 (NC) | No Connect | Internally unconnected pin; must remain floating or grounded per layout guidelines - not usable as spare I/O. |
| 5 (VCC) | Power Supply | Primary supply rail (1.65–5.5V); decoupling capacitor (0.1μF) required within 3mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65V–5.5V operation enables drop-in use across legacy 5V and modern ultra-low-power 1.8V systems without redesign. |
| IOFF Partial Power-Down | Active output disable at VCC = 0V prevents back-driving and latch-up in hot-swap or multi-rail power sequencing scenarios. |
| 5.5V-Tolerant Inputs | Allows direct connection to 5V buses (e.g., legacy peripherals) while operating from 1.8V/2.5V/3.3V rails - eliminates discrete level shifters. |
| Low ICC and ΔICC | 10μA max supply current + 500μA max additional draw under switching ensures minimal impact on battery life in portable devices. |
| Robust ESD/Latch-Up | 2kV HBM ESD rating and >100mA latch-up immunity meet industrial reliability requirements per JESD22-A114 and JESD78. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Same logic function and specs; TI part uses SOT-23-5 package (larger footprint, 2.9mm × 1.6mm) and has θJA = 204°C/W. | Higher thermal resistance suits lower-power or less thermally constrained layouts; pinout differs (A/VCC/Y/GND/NC vs. A/GND/Y/VCC/NC). | Select when existing PCB uses TI's SOT-23-5 land pattern or requires tighter thermal budget margin at 100mW dissipation. |
| 74AUP1G17GW,125 | NXP part offers lower ICC (≤5μA) and wider hysteresis (ΔVT ≥0.45V at 1.8V), but reduced drive (±4mA at 1.8V) and narrower VCC range (0.8–3.6V). | Optimized for sub-2V battery-powered wearables; insufficient for 5V-tolerant or 3.3V/24mA drive needs. | Prefer only in energy-critical 1.2V–1.8V systems where ultra-low static current outweighs drive and voltage flexibility requirements. |
Compared with SN74LVC1G17DBVR, the 74LVC1G17SE-7 offers superior thermal performance in compact space-constrained designs due to its smaller SOT353 footprint and lower junction-to-ambient resistance at high ambient temperatures; versus 74AUP1G17GW, it delivers broader voltage interoperability and higher output strength essential for industrial and automotive signal integrity.

FAQ
What is the minimum recommended bypass capacitor for 74LVC1G17SE-7?
A 0.1μF ceramic capacitor is required between VCC and GND, placed within 3mm of the SOT353 package. This minimizes supply impedance during fast output transitions, preventing ground bounce and ensuring specified propagation delay and noise immunity performance across temperature and voltage ranges.
Can 74LVC1G17SE-7 be used to buffer analog sensor signals?
No - it is a digital Schmitt-trigger buffer optimized for logic-level signal conditioning, not analog amplification or linear signal processing. Its hysteresis and switching thresholds are fixed digital parameters; applying analog voltages outside the defined VI range risks undefined output states or increased ICC.
Does the NC pin on SOT353 require PCB connection?
No - Pin 4 is internally unconnected and must remain floating or optionally tied to GND for mechanical stability; routing traces or vias to it is unnecessary and may compromise solder joint reliability or thermal performance in dense layouts.
How does IOFF behavior differ from high-impedance tri-state outputs?
IOFF disables the output stage when VCC = 0V, blocking both sourcing and sinking paths to prevent back-current - unlike tri-state, which requires active control and functional VCC. This enables safe power sequencing in multi-rail systems without external enable logic or supervision circuits.
