Product details
Overview
SN74AUP1G17DBVT from Texas Instruments is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in ultra-low-power digital systems. It features 0.8 V to 3.6 V supply operation, 5.1 ns maximum propagation delay at 3.3 V, 0.9 µA maximum ICC, and Ioff support for partial power-down mode - enabling robust noise immunity in battery-powered portable electronics such as tablets and notebooks.
For engineers reviewing the SN74AUP1G17DBVT datasheet, SN74AUP1G17DBVT pinout, SN74AUP1G17DBVT application, or SN74AUP1G17DBVT equivalent, key selection criteria include its hysteresis (ΔVT = 0.07–1.31 V), input threshold symmetry (VT+ and VT−), 3.6-V I/O tolerance for mixed-voltage interfacing, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G17DBVT implements a noninverting Schmitt-trigger logic gate with hysteresis on the input stage, enabling reliable switching under slow-rising or noisy signals. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining low dynamic power (Cpd = 4.4 pF typical at 3.3 V) and low input capacitance (Ci = 1.5 pF).
Designed for partial-power-down operation, the device integrates Ioff circuitry that disables outputs and limits leakage to 0.6 µA max when VCC = 0 V, preventing backflow current and protecting downstream circuitry during hot-insertion or power sequencing scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Propagation Delay (tpd) | ≤5.1 ns at 3.3 V, CL = 5 pF - enables timing-critical point-to-point signal buffering in high-speed digital interfaces. |
| Static Current (ICC) | ≤0.9 µA - extends battery life in always-on sensor nodes and portable devices operating at sub-1 µA system quiescent current. |
| Hysteresis (ΔVT) | 0.07 V min to 1.31 V max across VCC range - provides noise margins of up to 43% of VCC, rejecting EMI-induced glitches on long traces or unshielded lines. |
| Ioff Leakage | ≤0.6 µA at –40°C to +85°C - ensures safe isolation during power sequencing and prevents unintended biasing of powered-down subsystems. |
| Input Capacitance (Ci) | 1.5 pF typical - minimizes loading on high-impedance sources (e.g., crystal oscillators, analog comparators) and preserves signal edge integrity. |
| ESD Rating | 2000 V HBM, 1000 V CDM - meets industrial-grade robustness requirements without external protection components. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - N.C. | No internal connection | Unbonded pad; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 - A | Input | Schmitt-trigger input with hysteresis; accepts 0–3.6 V signals regardless of VCC, enabling mixed-voltage domain interfacing. |
| 3 - GND | Ground reference | Primary return path for logic and Ioff leakage currents; requires low-inductance connection to PCB ground plane. |
| 4 - Y | Output | Noninverting buffered output with balanced drive (±4 mA), 3.6-V tolerant, capable of driving light capacitive loads ≤30 pF. |
| 5 - VCC | Positive supply | Power rail for core logic and output drivers; requires local 0.1 µF ceramic bypass capacitor placed within 2 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables clean logic transitions from slow or noisy signals (e.g., mechanical switch debouncing, RC reset generators) without external hysteresis circuitry. |
| Ioff partial-power-down | Prevents back-current flow into powered-down sections, eliminating need for external isolation switches in multi-rail systems. |
| 3.6-V I/O tolerance | Allows direct connection to 3.3-V or 5-V legacy peripherals while operating from 1.2-V or 1.8-V supplies - reduces BOM count and layout complexity. |
| NanoStar™ packaging | Die-as-package construction achieves minimal footprint (1.6 × 2.9 mm) and thermal resistance (RθJA = 267.2°C/W), ideal for ultra-thin portable designs. |
| Low dynamic power (Cpd) | 4.4 pF typical at 3.3 V - cuts switching energy by >50% vs. standard AUC/AHC families, critical for high-frequency clock distribution in low-power SoCs. |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
|
Use Scenario: Conditioning slow-rising analog comparator outputs or mechanical switch signals before feeding into MCU GPIOs. IC Role / Device Role / Timing Role: Signal conditioner with hysteresis to eliminate chatter and ensure monotonic logic-level translation.

IC Role / Device Role / Timing Role: Low-jitter, low-propagation-delay buffer ensuring precise timing alignment of display control edges. Use Value: 5.1 ns tpd at 3.3 V meets <10 ns setup/hold windows for display ICs; NanoStar package saves board area near display connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVT | Wider VCC range (1.65–5.5 V); higher ICC (max 10 µA); no Ioff; 3.3-V I/O only. | Lacks partial-power-down capability; unsuitable for hot-swap or multi-rail sequencing where back-current must be blocked. | Select when interfacing exclusively with 3.3-V or 5-V systems and lowest static power is not required. |
| NC7SZ17P5X | Smaller SC-70-5 package (1.25 × 2.00 mm); similar hysteresis; no Ioff; max ICC = 1 µA. | Higher thermal resistance (RθJA = 284.1°C/W); lacks 3.6-V I/O tolerance - requires external clamping for >3.3-V inputs. | Select when board area is more critical than I/O tolerance or power-down safety, and supply is strictly ≤3.3 V. |
Compared with SN74LVC1G17DBVT and NC7SZ17P5X, the SN74AUP1G17DBVT uniquely combines sub-µA static power, Ioff-enabled system-level power management, and 3.6-V I/O tolerance - making it the only choice for battery-powered, multi-voltage, and hot-pluggable applications requiring guaranteed isolation during power transitions.

FAQ
What is the minimum supply voltage for reliable operation of the SN74AUP1G17DBVT?
The SN74AUP1G17DBVT is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional Schmitt-trigger behavior with VT+ = 0.3 V and VT− = 0.1 V, and delivers tpd ≤22.7 ns (CL = 5 pF). This makes SN74AUP1G17DBVT suitable for ultra-low-voltage microcontroller subsystems and energy-harvesting applications where supply rails dip below 1.0 V.
Does the SN74AUP1G17DBVT support hot insertion or partial power-down?
Yes. The SN74AUP1G17DBVT integrates Ioff circuitry that places both input and output terminals in high-impedance state when VCC = 0 V, limiting leakage to ≤0.6 µA over temperature. This feature enables safe hot insertion into live backplanes and prevents back-current damage during staged power-up sequences - a capability not present in standard LVC or AHC buffers.
Can the SN74AUP1G17DBVT interface directly with 5-V logic signals?
No. While the SN74AUP1G17DBVT inputs tolerate up to 4.6 V (per Absolute Maximum Ratings), its recommended operating VI range is 0–3.6 V, and its outputs swing only to VCC levels. For 5-V signal interfacing, use a dedicated level translator or select a 5-V-tolerant buffer like SN74LVC1T45. Direct 5-V input risks exceeding recommended conditions and degrading long-term reliability.
What is the purpose of Pin 1 (N.C.) on the SN74AUP1G17DBVT DBV package?
Pin 1 on the SN74AUP1G17DBVT DBV (SOT-23-5) package is a no-connect terminal with no internal bond wire or silicon connection. It may be left floating or tied to GND for mechanical stability and improved thermal conduction - but it must never be connected to VCC or driven, as it has no electrical function and could compromise package integrity if misused.
How does the hysteresis of the SN74AUP1G17DBVT improve noise immunity compared to standard CMOS buffers?
The SN74AUP1G17DBVT provides programmable hysteresis (ΔVT = 0.07–1.31 V depending on VCC), creating distinct high- and low-thresholds (e.g., VT+ = 1.88 V, VT− = 0.88 V at 3 V). This prevents multiple toggles during slow or noisy transitions - unlike standard CMOS buffers with single threshold - making SN74AUP1G17DBVT ideal for debouncing switches, cleaning RC-generated reset pulses, or conditioning analog comparator outputs.
