Product details
Overview
SN74AUP1G17DBVR from Texas Instruments is a low-power single Schmitt-trigger buffer in SOT-23 (5-pin) package, operating across 0.8 V to 3.6 V supply range. It delivers 5.1 ns max propagation delay at 3.3 V, 4.4 pF typical dynamic power capacitance, and 0.9 µA max ICC - enabling robust noise immunity and ultra-low static power in battery-powered portable systems.
For engineers reviewing the SN74AUP1G17DBVR datasheet, SN74AUP1G17DBVR pinout, SN74AUP1G17DBVR application, or SN74AUP1G17DBVR equivalent, key selection criteria include Schmitt-trigger input hysteresis (0.79 V min at 3 V), Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage interfacing, and verified performance down to 0.8 V supply.
Technical Context
This device implements a noninverting Schmitt-trigger gate with hysteresis (ΔVT = 0.79 V min at VCC = 3 V), enabling reliable signal conditioning of slow-rising or noisy inputs. Its balanced CMOS push-pull output drives ±4 mA at 3 V while maintaining rail-to-rail VOH/VOL compliance.
The AUP family uses TI's ultra-low-power process optimized for sub-1-µA ICC across full VCC range. Ioff circuitry ensures outputs enter high-impedance state during power-down, preventing backflow current and supporting hot-insertion in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC 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 |
| tpd (max) | 5.1 ns at 3.3 V, CL = 5 pF - enables timing-critical point-to-point buffering up to ~100 MHz |
| ICC (max) | 0.9 µA at TA = –40°C to +85°C - extends battery life in always-on sensor nodes and wearables |
| Cpd (typ) | 4.4 pF at 3.3 V - reduces dynamic power consumption in high-frequency toggle applications |
| ΔVT (min) | 0.79 V at VCC = 3 V - provides >26% hysteresis margin for noise rejection on slow-switching lines |
| Ioff (max) | 0.6 µA at TA = –40°C to +85°C - prevents leakage-induced logic faults during system sleep modes |
| VIH/VIL Thresholds | VT+ = 2.29 V, VT– = 1.24 V at VCC = 3 V - ensures clean switching despite ground bounce or supply ripple |
Pinout & Package
SOT-23 (5-pin) package, 1.60 mm × 2.90 mm body size, with exposed pad not present. Pin 1 = N.C., Pin 2 = A (input), Pin 3 = GND, Pin 4 = Y (output), Pin 5 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No internal connection | Must be left unconnected; no routing or soldering required |
| 2 | Input (A) | Schmitt-trigger input accepting 0–3.6 V signals; tolerant of slow edges and noise |
| 3 | GND | Primary reference for all input thresholds and output logic levels |
| 4 | Output (Y) | Noninverting CMOS output capable of sourcing/sinking ±4 mA at 3 V |
| 5 | VCC | Single supply pin; powers internal logic and output stage; requires local 0.1-µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable signal restoration of degraded or slow-rising waveforms without external RC networks |
| Ioff partial-power-down | Disables outputs and limits I/O leakage to ≤0.6 µA when VCC = 0 V - critical for multi-supply system isolation |
| 3.6-V I/O tolerance | Allows safe interfacing with higher-voltage peripherals (e.g., 3.3-V sensors) even when VCC = 1.8 V |
| NanoStar™ packaging | Die-as-package construction reduces parasitic inductance and improves thermal resistance (RθJA = 267.2°C/W) |
| Low input capacitance | Ci = 1.5 pF typical - minimizes loading on high-impedance sources such as crystal oscillators or analog comparators |
Applications
| Industrial Sensor Interface | Portable Device Power Sequencing |
|---|---|
Use Scenario: Conditioning slow-rising analog comparator outputs or mechanical switch bounce in factory automation nodes. IC Role / Device Role / Timing Role: Schmitt-trigger buffer restoring clean digital logic levels before MCU GPIO sampling.

IC Role / Device Role / Timing Role: Unidirectional voltage-tolerant buffer enabling safe 1.8-V → 3.3-V signal translation. Use Value: No external level-shifters needed; 3.6-V input tolerance allows direct connection to 3.3-V buses at 1.8-V VCC. |
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 | Higher ICC (10 µA typ), wider VCC range (1.65–5.5 V), no Ioff support | Lacks partial-power-down capability; unsuitable for hot-swap or multi-rail sleep modes | Choose when 5-V compatibility or higher drive strength is required and power-down isolation is unnecessary |
| NC7SZ17P5X | Lower hysteresis (ΔVT ≈ 0.3 V at 3.3 V), smaller SC70-5 package, no Ioff | Reduced noise immunity; cannot safely isolate during VCC ramp-up/down sequences | Prefer for space-constrained designs where ultra-low capacitance (1.2 pF) outweighs hysteresis and Ioff needs |
Compared with SN74LVC1G17DBVR and NC7SZ17P5X, SN74AUP1G17DBVR uniquely combines sub-µA static power, Ioff-enabled system-level power gating, and industry-leading Schmitt hysteresis - making it optimal for energy-sensitive, multi-voltage, and hot-pluggable applications.

FAQ
What is the maximum propagation delay of SN74AUP1G17DBVR at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP1G17DBVR is 5.1 ns at VCC = 3.3 V, CL = 5 pF, and TA = –40°C to +85°C. This value is guaranteed across temperature and voltage extremes, ensuring timing predictability in real-world embedded designs using SN74AUP1G17DBVR.
Does SN74AUP1G17DBVR support partial power-down operation?
Yes, SN74AUP1G17DBVR fully supports partial power-down via its Ioff feature. When VCC = 0 V, all inputs and outputs enter high-impedance states with leakage ≤0.6 µA, preventing back-current flow and enabling safe operation in multi-rail systems - a core design requirement validated in the SN74AUP1G17DBVR datasheet.
What is the input hysteresis (ΔVT) of SN74AUP1G17DBVR at 3 V supply?
At VCC = 3 V and TA = –40°C to +85°C, SN74AUP1G17DBVR guarantees ΔVT (VT+ – VT–) ≥0.79 V. This hysteresis provides strong noise margin for slow or noisy signals, directly enabling reliable operation in industrial environments without external filtering - a key specification confirmed in the Electrical Characteristics table of the SN74AUP1G17DBVR datasheet.
Can SN74AUP1G17DBVR interface between 1.8-V and 3.3-V logic domains?
Yes, SN74AUP1G17DBVR supports mixed-voltage operation: its inputs tolerate up to 3.6 V regardless of VCC, and its outputs swing rail-to-rail. With VCC = 1.8 V, SN74AUP1G17DBVR can safely accept 3.3-V inputs and drive 1.8-V loads - eliminating external level shifters in many portable and embedded designs using SN74AUP1G17DBVR.
What package type and dimensions does SN74AUP1G17DBVR use?
SN74AUP1G17DBVR uses the SOT-23 (DBV) package: 5-pin, 1.60 mm × 2.90 mm nominal body size, with standard lead pitch and footprint. This package is widely supported by pick-and-place equipment and PCB assembly processes, and its thermal resistance (RθJA = 267.2°C/W) is documented in the SN74AUP1G17DBVR datasheet.
